Bad on the day of ovulation. How does an ovulation test work? Is it possible to get pregnant before ovulation?

Collapse

U healthy women Ovulation occurs regularly. How to find out if conception occurred after ovulation? Neither a pregnancy test nor an ultrasound will give any result immediately after ovulation because hCG is not produced during the pre-implantation period. Once the fertilized egg attaches to the uterine wall and hormone secretion begins, a test can be done. Until this moment, a woman can record the initial signs of pregnancy, which are not always objective.

Favorable period for conception

Is it possible to get pregnant before or after ovulation? The maximum chance of conception exists on the day of ovulation. The favorable time after it is calculated in hours and averages less than a day. This is explained by the fact that the oocyte lives only 12-24 hours. The potentially dangerous period is about 8 days (7 days before the oocyte is released and 1 day after it), since sperm live from 2 to 7 days. That is, they can penetrate the tubes even before ovulation and wait for the egg there. In this case, conception occurs on the day the oocyte is released.

Ovulation

To calculate ovulation, you need to divide the average cycle length by two; the error is three days in both directions. This method is not very accurate because ovulation may occur earlier or later than the middle of the cycle. A test for LH (luteinizing hormone) in the urine can accurately determine the yield of the oocyte. An increase in LH levels indicates approaching ovulation. The test allows you to find out about ovulation a day before its onset with an accuracy of 99%.

Signs of pregnancy

Specific signs signaling a change in hormonal levels will help you understand that conception has occurred. Preimplantation symptoms of conception and fertilization are not reliable, but sometimes accurately indicate the presence of pregnancy.

Bloody issues

Minor bloody issues, appearing after ovulation, may indicate conception; this is implantation bleeding that accompanies the implantation of the embryo into the uterine wall. This discharge is often mistaken for the beginning of menstruation. But we cannot ignore the bleeding that appears repeatedly throughout the day or more. This could mean an impending miscarriage, a condition that requires medical attention.

Bloating

Long before toxicosis occurs, a woman may complain of increased gas formation and bloating. These symptoms can be considered a sign of pregnancy if they occur towards the end of the cycle.

Some note intolerance to certain foods and smells, unusual food preferences. These phenomena disappear over time, but having become pregnant for the second time, the woman already clearly knows what the occurrence of these symptoms indicates.

Abdominal cramps

Also, many women indicate such signs of pregnancy as heaviness in the lower abdomen and cramps, sometimes tingling and nagging pain. These symptoms may also indicate increased tone uterus, so if they continue for a week, then you need to consult a specialist.

Changes in the mammary glands

Soreness, enlargement and engorgement of the breast, enlargement and darkening of the areolas are the main signs that conception has occurred. These phenomena occur before menstruation, but at the beginning of pregnancy they are more pronounced and can last longer. A woman may also notice light discharge from the nipples, the mammary glands begin to produce colostrum.

High basal temperature

If fertilization has occurred, then the elevated basal temperature should remain throughout the second half of the cycle. Sometimes the sensations when an egg is released are mistaken for the onset of fertilization, since the symptoms that occur during ovulation are similar to signs of conception. It is safer not to rely on subjective feelings, but to wait until the 10th day of the expected pregnancy and conduct a test.

After fertilization, basal temperature rises. If the thermometer shows 37 degrees, this allows us to conclude that pregnancy is possible even before the delay. After ovulation and fertilization occur, increased production of progesterone begins. It is he who gives the increase to 37 degrees.

Normal temperature after fertilization is an unfavorable prognostic sign and indicates a lack of progesterone. This condition poses a risk of miscarriage and requires treatment.

Fatigue

TO initial signs pregnancy includes increased fatigue, sleepy state And constant feeling ailments caused by hormonal changes. After ovulation and conception, the body adapts to its new state and provides protection to the embryo. If pregnancy occurs after ovulation, immunity is automatically reduced so that the mother’s body does not reject the embryo, which it perceives as a foreign body.

Irritability
An informative sign of pregnancy is severe irritability and emotional lability, which is also a reaction to hormonal changes occurring in the body. If a woman is nervous and irritated for any reason, then this may indicate that conception has occurred.

Increased PMS symptoms

Unpleasant sensations after ovulation and conception may resemble discomfort before the onset of menstruation. They are evidence of the onset of pregnancy. Pronounced and long-term pain may indicate abnormal attachment of the egg, so if they last more than 14 days, then you should visit a doctor.

Stomach ache

In the first days after conception, mild pain in the sacrum and discomfort in the lower abdomen sometimes occur. More severe pain occurs with a threatened miscarriage or ectopic implantation, in addition to bleeding.

Gastrointestinal dysfunction

Sometimes the first signs of conception after ovulation are associated with dysfunction of the gastrointestinal tract. If more than a week has passed since the estimated moment of conception, the woman may experience the following symptoms:

nausea, urge to vomit;
heartburn;
increased gas formation;
heaviness in the stomach;
perversion of taste.

These symptoms occur when conception occurs after ovulation and the egg is implanted into the uterus. Before this happens, the hormonal levels remain at the same level and any changes in the functions of the gastrointestinal tract are not informative.

Cystitis

The early stages of fetal development in many women are accompanied by inflammation Bladder. The reason for this phenomenon is not so much that the growing uterus puts pressure on the bladder (it is still no larger than chicken egg), how much in hormonal changes in the body. weakens immune defense As a result, the infection penetrates the urinary organs and cystitis develops. Problems of this nature can haunt a woman throughout her pregnancy. Treatment is carried out antibacterial drugs who don't have negative influence for the fruit.

Signs of conception by day

For the fusion of gametes, a full-fledged egg must be released from the follicle. A mature cell is capable of fertilization and subsequent division. On what day after ovulation does conception and fertilization occur? Most often, on the same day, the life of the egg is short - about 12-24 hours.

First day

Sperm must travel a certain distance to enter the fallopian tube, where the egg awaits them. This process takes about 2-6 hours. After the struggle, the sperm penetrates inside and fertilization occurs. In most cases, there are no signs of conception after ovulation before implantation. A woman does not feel anything on the 1st day of pregnancy.
Second day
The immune system perceives the fertilized egg as a foreign body, therefore, on the 2nd day of pregnancy, the production of antibodies begins, the so-called immune attack. From this future mom feels tired and overwhelmed. In addition, a change may occur on the second day taste preferences, bloating and nausea, as well as signs of egg fertilization such as engorgement and tenderness of the mammary glands.

The third day

The first few days, including the 3rd day of embryo development, occur in the fallopian tube. A woman may lose her appetite, experience nausea and dizziness. Starting from the third day, the woman’s body begins to rebuild and prepare for implantation.

Fourth day

On the 4th day after the fusion of gametes, thanks to the peristalsis of the tubes, the embryo enters the uterus. Signs of pregnancy on this day: increased gas formation, bloating. Feeling foreign body in a stomach.

Fifth day

Implantation means the process of attachment of the embryo to the uterine mucosa, which occurs from 5 to 9 days from the moment of fertilization and lasts about 40 hours. If the embryo does not move into the uterine cavity, but continues to develop in the tube, then ectopic pregnancy. On the 5th day after the fusion of gametes, the temperature may rise, dizziness and chills may occur. A woman feels like she has a cold.

Sixth day

On day 6, there is an increase in basal temperature, which must be measured without getting out of bed in the morning. A nagging pain is felt in the lower abdomen, as before the onset of menstruation.

Seventh day

Signs of pregnancy on day 7 are: slight light brown or pink discharge. They can occur between the fifth and seventh day after gamete fusion, corresponding to embryo implantation.

Eighth day

The beginning of the second week of embryonic development corresponds to the first critical period formation. During this period of time, teratogenic factors lead to the death of the embryo. But if he survives, then he does not have any developmental defects. On the 8th day there is a feeling constant fatigue, headaches and dizziness. The expectant mother looks pale.

Ninth day

The embryo, which is at the stage of crushing, reaches the uterus and begins to sink into the mucous membrane. This sometimes causes minor implantation bleeding. Until day 9, signs of pregnancy are very scant and similar. Due to the fact that hormonal levels begin to change, the expectant mother feels very tired, so on the 9th day after the fusion of the gametes, the woman feels drowsy.

Tenth day

On the 10th day, the embryo is finally implanted into the uterine mucosa. Now you can determine the presence of gonadotropic hormone in the blood. Biochemical analysis blood test, which can be done from this day on, objectively confirms the onset of pregnancy. After day 10, you can use a highly sensitive test.

Eleventh day

For most women, the approach of menstruation is accompanied by some characteristic sensations: mood lability, nagging pain in the back or lower back, migraine, engorgement and breast enlargement. And if on the 11th day these signs are absent, then it is possible that you should no longer wait for your period.

Twelfth day

On the 12th day of embryonic development, the appearance of dyspeptic phenomena: changes in taste, nausea, vomiting, aversion to certain odors. These symptoms of fertilization occur in the vast majority of expectant mothers. At this time, the body itself can tell you what it needs for correct formation fetus, so women note a change in taste preferences. They may be attracted to those foods that seemed tasteless to them before pregnancy, and their previously favorite dishes may cause disgust.

Thirteenth day

Changes in mammary glands begin to occur immediately after conception, parallel to the processes occurring in the uterus. On the 13th day of pregnancy a common symptom After fertilization, there is discomfort in the mammary glands, and in some cases even slight discharge from them. The body is preparing for breastfeeding, the result of the changes may be darkening and swelling of the areola around the nipples.

Sixteenth day

From the 16th day of pregnancy, a neural plate is formed in the embryo, the ends of which connect and form a tube. This is how it begins nervous system. After this it is laid skeletal system embryo.

Carrying out the test

How to find out whether conception has occurred and whether pregnancy has occurred after ovulation? The accuracy of the test results depends on the timing of the test. In order for it to detect pregnancy before the onset of menstruation, you need to purchase a test with high sensitivity. Some products are able to show hCG concentrations starting from 10 mU/ml and record fertilization already on the 10th day. The second type of test is less sensitive and notes the presence of hCG only from 15-25 mU/ml, that is, after the first day of a missed period.

It often happens that conception occurs, but the test is negative. One of the reasons for this phenomenon may be non-compliance correct sequence carrying out the test specified in the instructions. The objectivity of the study can also be affected by drinking excessive amounts of liquid and conducting the test in evening time, which affects the concentration of the hormone in the urine.

If the second strip is poorly visualized, it is recommended to conduct secondary testing after a few days. Sometimes hCG increases slowly, and the test will record a false negative result up to 3 weeks after the fusion of gametes. In this case, a woman can focus on subjective signs of pregnancy.

Ovulation (from Latin ovum - egg) - the release of a mature egg capable of fertilization from the ovarian follicle into the abdominal cavity; stage of the menstrual cycle (ovarian cycle). Ovulation in women of childbearing age occurs periodically (every 21-35 days). The frequency of ovulation is regulated by neurohumoral mechanisms, mainly by gonadotropic hormones of the anterior pituitary gland and ovarian follicular hormone. Ovulation is promoted by the accumulation of follicular fluid and the thinning of the ovarian tissue located above the protruding pole of the follicle. The rhythm of ovulation, which is constant for every woman, undergoes changes within 3 months after an abortion, within a year after childbirth, and also after 40 years, when the body prepares for the premenopausal period. Ovulation stops with the onset of pregnancy and after extinction menstrual function. Establishing the date of ovulation is important when choosing the most effective time for fertilization, artificial insemination and in vitro fertilization.

Signs of ovulation

Subjective signs of ovulation may include short-term pain in the lower abdomen. Objective signs of ovulation are an increase in mucous discharge from the vagina and a decrease in rectal (basal) temperature on the day of ovulation with an increase in it the next day, an increase in the content of progesterone in the blood plasma, etc. Ovulation disorders are caused by dysfunction of the hypothalamic-pituitary-ovarian system and can be caused by inflammation genitalia, adrenal cortex dysfunction or thyroid gland, systemic diseases, tumors of the pituitary gland and hypothalamus, stressful situations. Lack of ovulation childbearing age(anovulation) is manifested by a disturbance in the rhythm of menstruation such as oligomenorrhea (menstruation lasting 1-2 days), amenorrhea, dysfunctional uterine bleeding. Lack of ovulation (anovulation) is always the cause of a woman's infertility. Methods for restoring ovulation are determined by the cause that caused anovulation and require a visit to a gynecologist and special treatment.

Ovulation and contraception

Some women experience peak sexual arousal around the days of ovulation. However, the use of a physiological method of contraception from pregnancy, based on sexual abstinence during ovulation, is especially difficult for young spouses, whose frequency of sexual intercourse reaches quite high level. In addition, with strong love emotions and nervous stress Additional ovulation may occur (especially with episodic, irregular intercourse) and then not one, but two eggs mature in one menstrual cycle. This should be kept in mind when choosing one or another method of contraception.

Physiology of the ovulation cycle

As soon as every healthy girl aged 11-15 years begins to menstruate, which is an indicator of her body’s readiness for childbearing, problems arise associated with counting the days of the menstrual cycle and the legitimate question of why menstruation does not occur, or vice versa, why it does not occur long-awaited pregnancy. This forces a woman to think and wait all the time, to be in the dark about what is happening to her every month. And so every month for decades.

Duration of menstruation and cycle

Ideal menstruation lasts 3-5 days and repeats every 28 days. However, for some women this cycle takes 19 days or even less, while for others it lasts from 35 to 45 days, which is a feature of their body, and not a violation of menstrual function. The duration of menstruation can also vary within a week depending on the body. All this should not cause alarm in a woman, but a delay of more than two months, called opsometry, or more than six months - amenorrhea, should alert the woman and force her to find out the reason with a gynecologist.

Duration of the menstrual cycle

- it's complicated physiological process, lasting in women up to 45–55 years. It is regulated by the so-called genital centers located in the middle part diencephalon– hypothalamus. Changes that occur during menstrual cycle, are most pronounced in the uterus and ovaries. In the ovary, under the influence of hormones produced by the ovarian follicles, partly by the adrenal cortex and testes, the growth and maturation of the main follicle, which contains the egg, occurs. A mature follicle ruptures and the egg, along with follicular fluid, enters the abdominal cavity and then into the uterine (fallopian) tube. The process of rupture of the follicle and the release of a mature (suitable for fertilization) egg from its cavity is called ovulation, which at 28 daily cycle occurs most often between the 13th and 15th days.

Corpus luteum, estrogen, progesterone

At the site of the ruptured follicle, a corpus luteum forms. These morphological changes in the ovary are accompanied by the release of reproductive organs steroid hormones– estrogens and progesterone. Estrogens are secreted by the maturing follicle, and progesterone is secreted by the corpus luteum.

The release of estrogen has two maximums - during ovulation and during the period of maximum activity. corpus luteum. So, for example, if normal content estrogen is about 10 mcg/l, then during ovulation it is about 50 mcg/l, and during pregnancy, especially towards the end, the estrogen content in the blood increases to 70-80 mcg/l due to a sharp increase in the biosynthesis of estrogen in the placenta .

Together with progesterone, estrogens promote implantation (introduction) of a fertilized egg, maintain pregnancy and promote childbirth. Estrogens play an important role in the regulation of many biochemical processes and are involved in carbohydrate metabolism, in the distribution of lipids, stimulate the synthesis of amino acids, nucleic acids and proteins. Estrogens promote calcium deposition in bone tissue, delay the release of sodium, potassium, phosphorus and water from the body, that is, they increase their concentration both in the blood and in electrolytes (urine, saliva, nasal secretions, tears) of the body.

The release of estrogen is controlled by the anterior pituitary gland and its genadotropic hormones: follicle-stimulating hormone (FSH) and luteinizing hormone (LH).

Under the influence of estrogens, in the first phase of the menstrual cycle, called follicular, regeneration occurs in the uterus, that is, the restoration and growth of its mucous membrane - the endometrium, the growth of glands that elongate and become convoluted. The mucous membrane of the uterus thickens 4-5 times. In the glands of the cervix, the secretion of mucous secretion increases, the cervical canal expands, and becomes easily passable for sperm. In the mammary glands, epithelium grows inside the milk ducts.

In the second phase, called the luteal phase (from the Latin word luteus - yellow), under the influence of progesterone, the intensity metabolic processes decreases in the body. The growth of the mucous membrane of the uterine body stops, it becomes loose, swollen, a secretion appears in the glands, which creates favorable conditions for the attachment of a fertilized egg to the mucosa and the development of the embryo. The glands stop secreting mucus, and the cervical canal closes. In the mammary glands, alveoli arise from the overgrown epithelium of the end sections of the mammary ducts, capable of producing and secreting milk.

If pregnancy does not occur, the corpus luteum dies, the functional layer of the endometrium is rejected, and menstruation occurs. Monthly bleeding varies from three to seven days, the amount of blood lost ranges from 40 to 150 g.

Timing of ovulation

It should be noted that different women there is a noticeable difference in the timing of ovulation. And even for the same woman, the exact timing of the onset varies from month to month. Some women have extremely irregular cycles. In other cases, cycles may be longer or shorter than the average of 14 days. IN in rare cases It happens that in women with a very short cycle, ovulation occurs around the end of the period menstrual bleeding, but still in most cases ovulation occurs quite regularly.

If for one reason or another ovulation does not occur, the endometrial layer in the uterus is thrown out during menstruation. If the fusion of the egg and sperm has occurred, then the cytoplasm of the egg begins to vibrate very strongly, as if the egg is experiencing an orgasm. Sperm penetration is the final stages of egg maturation. All that remains of the sperm is its nucleus, where 23 chromosomes are tightly packed (half the set of a normal cell). The sperm nucleus now quickly approaches the egg nucleus, which also contains 23 chromosomes. The two nuclei slowly touch. Their shells dissolve and their fusion occurs, as a result of which they are divided into pairs and form 46 chromosomes. Of the 23 chromosomes of the sperm, 22 are completely similar to the chromosomes of the egg. They determine all physical characteristics of a person except gender. The remaining pair from the egg always contains an X chromosome, and from the sperm there may be an X or Y chromosome. Thus, if there are 2 XX chromosomes in this set, then a girl will be born, if XY, then a boy.

Research carried out in “ National Institute medical problems environment” (North Carolina) showed that not only the actual conception of a child, but also its gender depends on the time of conception in relation to the time of ovulation.

The chance of conception is highest on the day of ovulation and is estimated at approximately 33%. High probability also observed on the day before ovulation - 31%, two days before it - 27%. Five days before ovulation the chance of conception is estimated to be 10%, four days before ovulation is 14% and three days before ovulation is 16%. Six days before ovulation and the day after ovulation, the likelihood of conception during sexual intercourse is very low.

Considering that the average “life expectancy” of sperm is 2-3 days (in rare cases it reaches 5-7 days), and female egg remains viable for about 12-24 hours, then maximum duration The “dangerous” period is 6-9 days and the “dangerous” period corresponds to the phase of slow increase (6-7 days) and rapid decline (1-2 days) before and after the day of ovulation, respectively. Ovulation, as noted above, divides the menstrual cycle into two phases: the phase of follicle maturation, which, when average duration cycle is 10-16 days and the luteal phase (phase of the corpus luteum), which is stable, independent of the duration of the menstrual cycle and is 12-16 days. The corpus luteum phase refers to the period of absolute infertility; it begins 1-2 days after ovulation and ends with the onset of a new menstruation.

Ovulation – important stage menstrual cycle, during which the follicle ruptures and an egg enters the fallopian tube. This process makes fertilization and pregnancy possible. But how do you understand that ovulation has occurred?

The onset of ovulation occurs in the middle of the menstrual cycle, and the entry of the egg into the fallopian tube is considered a kind of peak. With a cycle duration of 27 – 30 days of egg release can be expected at 13 – 16th day from the start of menstrual flow.

You need to understand that every woman’s body has its own individual characteristics. In some cases the impact external factors can cause disruption of the menstrual cycle, so ovulation will occur later or earlier than expected.

Fertilization does not only occur on the day of ovulation. The egg remains viable for 24 hours, and healthy sperm remain active for more than 72 hours. Therefore, conception can occur within 4 days: 3 days before and 1 day after the rupture of the follicle.

Why is ovulation determined?

Rupture of the follicle, the entry of the egg into the fallopian tube means the onset of favorable period to conceive a child. Therefore, determining ovulation is necessary married couples those who carefully plan the future, and girls who have been unable to get pregnant for a long time.

Ovulation, along with other stages of the menstrual cycle, is an indicator of a woman’s health. If a couple fails to conceive a child within 2–3 months, this may indicate the development of a pathology. It will help to determine the cause of the problem comprehensive examination both partners.

It is important to know when ovulation occurs and if a man’s spermogram is abnormal. If there is a violation of the motility, viability and number of sperm, then conception can occur only with sexual intercourse 1 day before or during the release of the egg. In such cases, it is recommended to refrain from intimacy for 2 – 3 days to increase sperm count and increase chances of fertilization.

There is an opinion that determining the release of an egg helps to plan the sex of the unborn child. Sperm with a Y chromosome (“male”) are highly motile, but do not live long. However, cells with the X chromosome (“female”) are active for 72 hours. Therefore, during intimacy on the day of ovulation, a boy may be born within 2 – 3 days before the release of the egg - girl. However, experts do not confirm this theory, because the effectiveness of the method does not exceed 50%.

Main signs (symptoms) of ovulation

How to determine whether ovulation has occurred on your own? Every woman can notice the development of some changes in the body during the release of the egg. It is worth considering each of the symptoms in more detail.

Increased libido

During ovulation, a woman's libido increases, she becomes easily excitable, and sensuality increases. This is due to an increase in the amount of androgens in the bloodstream. Also noted are memory sharpening, stress resistance, and increased endurance. Scientists have proven that during this period a woman acquires a special aroma that attracts men.

The appearance of mucous discharge

During ovulation, a woman may notice an increase in the volume of discharge, which is associated with an increase in the production of estrogen and progesterone. During this period, cervical mucus is quite liquid, sticky and viscous. Sometimes dense clots may appear in the discharge. Similar consistency cervical mucus Helps sperm reach the egg.

During the completion of the egg release process, a woman may notice yellowish discharge, which may have pink streaks.

Mild nagging pain in the lower abdomen

Not every woman notices the appearance of unpleasant sensations during follicle rupture. This sign develops only in 1/5 of women. Nagging pain in some cases is accompanied by discharge small quantity blood.

Doctors explain the development of pain syndrome by the formation of a Graafian vesicle, which stretches the ovary. In some cases, pain appears when follicular fluid enters the uterine cavity, which has a contractile effect. It should be noted that pain syndrome usually localized on one side: left or right. This is due to the alternate work of the ovaries.

Important! If the pain in the middle of the menstrual cycle is cutting in nature and continues for 2 – 3 days and getting in the way full life, then consultation with a specialist is necessary. The doctor will be able to determine the cause of the development unpleasant symptom and prescribe the necessary therapy.

How doctors determine the onset of ovulation

A gynecologist will help you accurately determine whether ovulation occurred. Doctor during gynecological examination will be able to determine a woman’s readiness to conceive based on her condition internal organs. The gynecologist may note a sharp increase in the amount of cervical fluid, softening of the cervix, and the appearance of a “pupil symptom” when mucous discharge can be seen through the cervix. Such symptoms can begin 2 days before ovulation and last 3-4 days.

An ultrasound will allow you to determine with 100% certainty the time of release of the egg. The study allows you to monitor the development of the follicle, its rupture and the release of the egg. Ultrasound monitoring is one of the most precise methods determining the onset of ovulation.

Biochemical screening will help accurately determine ovulation. This technique is rarely used to predict the day when an egg will be released from the follicle due to its high cost. However, it helps to accurately determine the presence of the process of release of the egg from the follicle. Therefore, a blood test is prescribed in cases where a woman cannot become pregnant for a long time.

Testing methods

How do you know when ovulation has occurred? For this purpose, it is recommended to use the following methods:

Test to determine ovulation. The method is based on determining the concentration of luteinizing hormone in urine. The test will allow you to accurately determine the day of ovulation, but taking certain medications may reduce the accuracy of the results. medicines
This indicator a woman can measure herself. It is enough in the morning, without leaving your bed, to measure your body temperature rectally. It is important to carry out manipulations strictly at the same time. If the indicator rises to 37.2 within a few days, this indicates the maturation of the egg and imminent ovulation. 1 day before the release of the egg, the temperature drops sharply. The technique is simple, but has low accuracy
Calendar method. First you need to determine the total duration of the menstrual cycle. The resulting number must be divided in half; ovulation can occur in 1 – 2 days before and after the received value. For example, if the cycle is 32 days, then ovulation should occur on 15 – Day 17 However, any errors in nutrition, infectious diseases, stress can affect the duration of the menstrual cycle, which significantly reduces the effectiveness of this technique

Ovulation is an important stage of the menstrual cycle, without which conceiving a child becomes impossible. Determining the time of release of the egg allows us to identify disorders of the female reproductive organs, plan your pregnancy wisely. Remember, when figuring out the timing of ovulation, you should not focus on problems with conception. You just need to enjoy life, and pregnancy will definitely come.

Ovulation is a state in which the female body is ready to conceive. Signs of ovulation are signals indicating readiness for fertilization. Some of them warn about readiness, others - about the end of ovarian maturation, and others - about problems of the female body.

Relevant selections. Before the ovary matures, the composition of the mucus secreted by the cervix changes. Usually the discharge becomes profuse, watery, and resembles a raw egg. In the absence of ovarian maturation, the mucus resembles a thick cream and becomes sticky. Sometimes it is completely absent.
High sexual desire. The female body is most excited and ready for sexual intercourse. The body is ready for conception, this explains the attraction.
Increase in basal temperature. This is the main sign of ovarian maturation. The temperature changes by about a couple of degrees. An increase in temperature promotes the release of the hormone progesterone.
Changes in the cervix. The uterus rises a little, opens and softens. This process leads to a change in the composition of the mucus.
Changes in the mammary glands, pain. Most women experience breast pain. Increased sensitivity is due to increased hormone levels, which promotes conception.
Characteristic pain. Occurs on the right or left side. The pain lasts from several minutes to days. The cause of discomfort is the release of the egg from the ovary.
Increase in luteinizing hormone. The hormone is responsible for stimulating the body, producing healthy and mature cells. When the ovary matures, the hormone is contained in small quantities, but as it grows, the body begins to prepare for conception.

These are the main signs that a woman is ready to conceive. They are of a purely individual nature. They can appear and subside. It all depends on the characteristics of the body.

Feels a great sex drive

Sensations during cell maturation

When the cell matures, women often experience cutting, stabbing, cramping or pulling pain in the lower abdomen, as well as nausea. The pain lasts for about an hour. May bother you for several days. The cause of discomfort is the exit mature ovary from the follicle. In the presence of severe pain on the right or left, you need to contact a gynecologist.

What to do if the pain is severe? With strong unpleasant sensations The doctor prescribes painkillers. Advanced cases require hormonal contraceptives, suppressive signs of ovulation, symptoms in a woman’s body. A calm, relaxing environment with drinking plenty of fluids and proper diet.

Pain is often associated with contractions of the uterus and fallopian tubes. After the ovary is released, pain rarely occurs. Severe discomfort indicates gynecological disease. Such pains are intense and periodic. Formed during inflammation of the ovaries and other reproductive organs.

Increased libido, as one of the signs of ovulation, indicates a favorable time for conception. After the end of the period, sexual desire suddenly disappears.

Women experience sudden mood swings. Irritability often comes in attacks, followed by tearfulness. Activity and physical strength appear. However, after a short period of time, apathy and fatigue sets in.

What do you need to know?

Today there are three types of ovulation:

premature;
timely;
late.

Premature is characterized by the early release of the egg. The reason for this phenomenon is intense sexual intercourse, stress, exercise, diet, hormonal disbalance. Most often occurs due to sudden weight loss, nervous breakdown or overvoltage. Late is observed with hormonal imbalances. To determine this, the doctor prescribes an ultrasound.

If not stable cycle It is difficult for a woman to draw a conclusion about the timing and possibilities of conception, since hormonal system works unstable.

A mature egg has a lifespan of 24 hours. During this period, pregnancy occurs. The process of attachment of a fertilized cell itself lasts for a week.

Ovulation period, signs and symptoms are associated with the release of only one egg. It is not necessary that the process will occur every menstrual cycle. The whole process is extremely sensitive to:

stress;
climate change;
lifestyle;
infectious diseases.

Signs of conceiving a child

It only takes a few days for a woman to become pregnant. There are signs of conception after ovulation. Among them stand out.

High basal temperature.
Increased appetite, increased taste buds.
Reaction to smells, sounds.
Enlargement of the mammary glands.
Apathy, fatigue, increased irritability.
Changes in vaginal discharge.

High basal temperature can be a sign of conception

There are characteristic signs of pregnancy after ovulation. These include.

The first and main sign of pregnancy after ovulation is the absence of menstruation. However, this only applies to cases where menstruation is regular.
Breast enlargement and increased sensitivity. This is due to changes in hormonal levels. Almost from the first days, a woman’s breasts prepare for the upcoming feeding.
Change in taste preferences. Occurs due to a lack of vitamins, useful substances. Therefore, there is a craving for a certain product. At the same time, a woman may want inedible things: chalk.
Urges to frequent urination. It is explained by strong compression of the bladder, which leads to urge.
Fatigue quickly. Almost from the first days, a woman experiences drowsiness, fast fatiguability. There is a decrease in memory and attention. The reason for this is hormonal changes that occur in female body.

How to determine ovulation?

You can determine your readiness to conceive without conducting tests or analyses. To do this, just listen to how you feel. The article above lists the main signs and symptoms of ovulation by day. These changes can not only be felt, but also seen.

In difficult cases, you should consult a doctor. During the examination, changes in the cervix are observed. It becomes loose, soft, and changes position.

The main signs of ovulation, which are easy to determine at home, include:

Determination of basal temperature. Every day before getting up, it is necessary to measure the temperature in the rectum. Measurements take five minutes mercury thermometer. The readings are recorded in a separate notebook. If observed sharp jump temperature, this indicates the release of the egg. The method provides guarantees in 70% of cases.
Maintaining a calendar. Menstruation occurs two weeks after ovulation. With a stable cycle of 28-30 days, the release of the egg occurs on days 14-15. You can make accurate calculations using online calculators.
Using tests. Accurate and most easy way determining readiness to conceive at home. Tests are sold at any pharmacy. The method of application is identical to that of pregnancy tests. The only difference is that the presence of luteinizing hormone is now determined.

If there are no signs of pregnancy after ovulation, you need to take into account the fact that there is always a factor of failure in the female body. Reasons for this:

stress;
overwork;
illness;
trips.

As a result, the deadlines are significantly shifted. Accordingly, pregnancy can occur on days that were considered “empty”.

No signs of ovulation

There are times when ovulation, its signs, characteristic symptoms and there are no sensations. In such cases, the doctor diagnoses “anovulation”. This phenomenon causes infertility. Don't be afraid of the situation that has arisen. The problem lies in hormonal disorders. The gynecologist usually prescribes hormonal therapy.

When nothing happens, that's a problem.

Characteristic symptoms:

lack of menstruation, cycle disruption;
irregular basal temperature;
reduction of PMS symptoms;
uterine bleeding.

Often the inability to conceive is associated with regular stress. A strong desire to get pregnant, fears on this basis lead to the opposite effect. A course of psychotherapy and complete and long rest are prescribed.

As a treatment, it is important to properly build a lifestyle and diet. If you have low body weight, you need to gain weight. In case of regular strong physical activity- everything is reduced to a minimum.

One of the reasons for the absence of signs of ovulation in a woman is obesity. The doctor prescribes a diet to lose 10% of body weight.

The gynecologist can prescribe medications that promote cell maturation and release. Drugs are prescribed to stimulate luteinizing hormone. Studies have shown that after taking the drugs, approximately 40-50% of women have signs of ovulation and corresponding sensations.

Treatment is prescribed only by a gynecologist after testing. Self-medication can be dangerous and signs of pregnancy will not appear after ovulation.

What is it, ovulation?

Not every day of the menstrual cycle is suitable for conceiving a child. Only within one day will a woman be able to become pregnant, and if this does not happen, then after 10-14 days menstruation will occur. In order for fertilization to take place, the fusion of a sperm and a mature egg is necessary.

However, a woman’s body is not adapted to the release of female reproductive cells short term. It must mature in the follicle of one of the ovaries, and then come out.

The process of rupture of the follicle capsule and subsequent release of the egg is called ovulation. Speaking in simple words, ovulation is the only day in the menstrual cycle when a woman is able to become pregnant.

Hormones needed for ovulation

One of the main reasons female infertility is a hormonal failure in which the egg in the ovary either does not mature, or the capsule of the dominant follicle does not break through, and it continues to increase, forming follicular cyst. Favorable conditions For ovulation to occur, the presence of normal concentrations of the following hormones in a woman’s body is assumed:

Estradiol – is responsible for the growth of the dominant follicle and endometrium. If this hormone is not enough, then the dominant one will not be released from the mass of antral follicles.
Luteinizing hormone (LH) tends to increase as the follicle matures. As a result, the LH surge ruptures its capsule and the egg has the opportunity to come out and enter the fallopian tube.
Follicle-stimulating hormone (FSH) is responsible for the process of follicle maturation, like estradiol. The hormones FSH and LH are complementary, so determining their concentrations in isolation from each other will not be informative.
Testosterone - an excess of this hormone prevents both the maturation of the egg and the rupture of the capsule of the dominant follicle.

Sometimes a woman is diagnosed with such dysfunctions endocrine system, which constantly prevent the onset of ovulation and which cannot be cured completely. In such cases, doctors try to at least temporarily bring the state of hormones back to normal so that conception can occur.

When is the day of ovulation?

Despite the fact that a woman is ready to conceive a child in just a day, the main question remains: on what day after menstruation does ovulation occur? If we look medical literature, then the answer to this is very clear: ideally, the release of the egg from the ovary should occur in the middle of the cycle.

But every woman’s body is individual, so both early and late ovulation can be observed. The cause of these deviations from the norm is hormonal imbalance:

For early ovulation characteristic increased concentration estradiol and FSH, as well as testosterone levels close to the lower limit of normal.
For late ovulation characterized by low concentrations of estradiol and high performance testosterone.

It is impossible to accurately calculate the day of ovulation in advance. However, there are special examinations, which allow the most reliable prediction of the timing of the release of the egg from the dominant follicle.

If a woman knows what period of time in her cycle is most favorable for conception, then she can use this both for pregnancy planning and for contraception purposes.

BT schedule– the moment of ovulation is displayed on it by a sharp one-day drop in temperature by 0.3 -0.4 degrees. The next day, the temperature rises by 0.2 degrees and stays at approximately this value for two days, after which it rises to 37 degrees and above.

As a result, a step is formed on the graph between the lowest temperature value and the subsequent increase. This step marks the day of ovulation.

The problem with tracking the release of an egg using graphs is that a woman can only find out about impending ovulation a day before it (at the moment the temperature drops).

Ovulation tests– the approaching day favorable for conception is displayed on the test with two bright stripes. This means that over the next 36 hours the follicle capsule will break through, the egg will enter the fallopian tube and will be suitable for fertilization within 24 hours.

One package contains several test systems - this allows you to observe how the color of the test strip becomes brighter.

Question: There is a weak second line in the ovulation test, what does it mean?

If the second line of the ovulation test is weak, this either means that the LH concentration has not yet increased and dominant follicle not ripe, or indicates that ovulation has already passed. However, this method of determining ovulation has one significant drawback.

The fact is that the reagent in the test system becomes active only if the concentration of LH in the body increases. But it may happen that the dominant follicle in a woman is not mature and does not exceed 9 mm in diameter, and the LH peak still occurs.

Thus, the test will give a false positive result.

Ultrasound folliculometry– is the most in an exact way predicting the day of ovulation. In the first phase of the cycle, the doctor can observe the growth of the dominant follicle and draw a conclusion about when its capsule will break through.

After the day of expected ovulation, you need to visit the ultrasound room again to make sure that it has taken place: characteristic features in the first 2-3 days there will be the presence of a corpus luteum and fluid in the retrouterine space.

How does the ovulation process occur?

When the dominant follicle reaches 18–22 mm in diameter, this means that the egg in it is fully mature and ready to be released. The entire process of ovulation can be considered sequentially:

A signal is sent to the anterior pituitary gland, causing this part of the brain to intensively produce luteinizing hormone. After a few hours, LH reaches a peak of 17 – 77 mU/ml.
The maturing follicle forms a tubercle on the surface of the ovary. Along with the increase in LH, there is a rapid increase in estradiol, as a result of which the size of the dominant follicle reaches 22 mm.
After the onset of increased LH secretion, a signal is sent from the brain to the fallopian tube that is closest to the ovary about to ovulate. The oviduct funnel is located above the ovary so that fallopian tube there was an opportunity to capture the egg.
Under the influence of the LH peak, the wall of the dominant follicle closest to abdominal cavity, becomes thin, and its integrity is violated.
The egg leaves the follicle along with follicular fluid, which will nourish the female sex cell until the moment she is fertilized.
The fallopian tube, with the help of cilia, captures the egg and carries it inside its cavity, where it meets the sperm.

All these processes occur within 24 to 36 hours and for most women are completely invisible. As a rule, only signs of a subsequent increase in progesterone are noticeable: increased appetite, breast tenderness, etc.

A small part of the fair sex feels when a period favorable for conception has arrived, let’s describe possible signs, symptoms and sensations on the day of ovulation. First of all this:

Tingling in the lower abdomen on the left or right may be a symptom of a maximally enlarged dominant follicle, the shell of which will burst in the near future.
A sudden increase in appetite may indicate not only an increase in progesterone, but also a hormonal change that occurs during ovulation.
Bloody discharge - a few drops of light brown color indicate that the egg was released from the follicle 3-4 hours ago. However similar symptom Happens only to a small number of women. And if intermenstrual bleeding is present, then it is necessary to make sure that it is ovulation that provokes it.
Increased sexual desire is associated with changes in hormones and changes in the phases of the menstrual cycle.
The appearance of stretching clear discharge. Their consistency is similar to raw egg white. During the period of ovulation, the “thread” of such secretions can be stretched to 5-7 cm in length.

If you plan sexual intercourse as ovulation symptoms appear, these attempts may not lead to pregnancy. The fact is that most signs appear when ovulation is either about to begin or has already occurred.

During this period of time, sperm may not have time to reach fallopian tube(it takes them several hours to do this, but the egg lives only from 12 to 24 hours).

On what day after ovulation can you take a pregnancy test?

There are different reasons, which determine a woman’s desire to find out about her pregnancy as early as possible: from banal impatience to the need to take special drugs to maintain the vital activity of the embryo.

When the question arises on what day after ovulation you can take a pregnancy test, you need to take into account that everything depends on the time when the fertilized egg was implanted into the uterus.

Early implantation, 3–5 days after ovulation. The test will show a weak second line already on day 9.
The most common implantation dates are 6–8 days. In this case, the test will show a weak second line on the 11th day after ovulation.
Late implantation, on days 9–12. The test will begin to show a weak second line starting 13–14 days after ovulation.

However, it is almost impossible to determine the day of implantation. The only exceptions are cases when this process is displayed on the BT chart as a one-day drop in temperature by 0.3 - 0.4 degrees (implantation retraction).

But not all women have a basal temperature that responds to the implantation of the fertilized egg.

Normally, a woman can have 1-2 anovulatory cycle. If there is no ovulation for several months, this signals that it is necessary to take hormone tests and show the results to the doctor.

As additional examination You can do an ultrasound of the uterus and appendages, as well as a picture of the sella turcica. Among the reasons why there is no ovulation are the following:

Disruption endocrine glands – the dominant follicle either does not mature or does not rupture in time, developing into a cyst. Inability to conceive due to malfunction endocrine system is quite common and difficult to correct.

As a rule, the production of not one hormone, but several at once, is disrupted - this complicates the treatment process.

Overweight or dystrophy– any serious deviations in body weight from the norm provoke the body to work for wear and tear. The body instinctively senses that conditions for conception are unfavorable, so the brain, month after month, may not send impulses to the pituitary gland and hypothalamus to sufficiently produce the necessary hormones.

Increased stress tension– suspension of reproductive functions occurs for the same reason as serious deviations in body weight from the norm. The body begins to actively fight stress and regards the environment as unfavorable for bearing a child.

Excessive loads – physical stress may be accompanied not only by the absence of ovulation, but also by the absence of menstruation. Reproductive functions come back when a woman refuses excessive loads and for several months changes his lifestyle to a more relaxed one.

Most causes of inability to conceive are due to improper hormone production. Therefore, in addition to a gynecologist, you can also visit an endocrinologist, who will examine hormonal levels and the functioning of the endocrine system in more detail.

If there is no ovulation for several months, this is a reason to go to the hospital and not self-medicate. Firstly, it can further aggravate hormonal imbalance, and secondly, it will take away precious time, which would be better spent on an adequate course of treatment.
