How to calculate the day of ovulation with a regular cycle. How to calculate the day of ovulation. We increase the likelihood of getting pregnant

An ovulation calculator is one of the ways to determine the most favorable days for conceiving a child. After all, conceiving a child is absolutely healthy couple It’s not always easy, if you don’t “get” on a favorable day, then pregnancy won’t occur. Some people are luckier and pregnancy occurs quickly, while others have to wait several months. Our ovulation and conception calculator will help you calculate that exact time.

But keep in mind that the results obtained may not be entirely reliable. The female body is very mysterious, and sometimes phenomena that are not entirely clear to medicine occur in it. For example, ovulation can occur towards the end of the menstrual cycle or vice versa in the first third (whereas it should be exactly in the middle). There are often stories on the Internet from women who claim that they became pregnant on days that were absolutely safe in terms of the likelihood of conception. So, an online ovulation calculator should not be considered as an independent means of contraception. It will be useful as additional means for some categories of women.

As is known, today the most effective effective means contraception are combined hormonal pills and the Mirena spiral. But, unfortunately, hormonal contraceptives have many contraindications and side effects. And not all healthy women are recommended to take them... For example, if a woman has only one healthy sexual partner, but sex life not regular - 1-2 times a month, or even less often, then you can use more safe methods- spermicides, and on dangerous days, as a supplement, also condoms. Dangerous days can be determined by doing some calculations. You need to know the length of your menstrual cycle. Moreover, if it is irregular, then you must first calculate the average value, taking the last 6-12 months as a basis. Next, we calculate exactly the middle of the cycle. This way we get the approximate day of ovulation. We add a week before and a week after - the so-called dangerous time. Thus, half of the month is “dangerous” for a woman, and half is relatively “safe”. If you don’t want to count on paper and trust software calculations more, our ovulation calculator is at your service - calculate favorable and unfavorable favorable days To conceive, you can right now by entering some data.

Now about something more pleasant - about planning a pregnancy using an online calendar. Here mistakes are no longer so scary, even if they happen. Using the program presented on this page, you can calculate the days most likely for pregnancy. It turns out there are already 9 of these days, or even more! But with frequent sexual intercourse, the number of viable sperm becomes smaller, which means the chances of conception are lower. Better to save your energy. Therefore, we not only use an online ovulation calculator, but also practice the good old way - measuring basal temperature. If financial possibilities allow, we buy tests to determine ovulation. The onset of ovulation is indicated by an increased (above 37 degrees) basal temperature (taking into account possible factors, in addition to pregnancy, which could give such a reaction) and positive test for ovulation. You can also confirm the release of an egg from the ovary using an ultrasound examination. There are also subjective signs, such as increased sexual desire, pain in the lower abdomen or from the ovary and fallopian tube, the appearance of clear, rather profuse vaginal discharge.

If you only had part of the evidence of ovulation, but conception did not occur, do not worry. According to statistics, very few people can get pregnant in the first 1-3 months of trying. small quantity steam. But doctors generally say that you need to start worrying if pregnancy does not occur for more than 10-12 months of sexual activity without contraception. The fact is that that most favorable day does not happen every menstrual cycle - so, calculating an ovulation calculator is only half the battle. Psychologists recommend to achieve quick results just relax and stop counting and calculating things, making love in certain positions and according to the clock, etc. Stress has too negative an effect on our body. So if you're in a rush to become parents, just go on vacation and enjoy each other's company! And the printed ovulation and conception calculator will then become for you one of the pleasant reminders associated with the period of planning a baby.

Perhaps all this may be quite difficult to believe, but doctors say that it is a fact. Namely, they say that in the whole month there is only one single day on which a full-fledged, absolutely healthy woman reproductive age can successfully become pregnant. And in some exceptional cases a similar day can occur twice directly during one single menstrual cycle. However, in the overwhelming majority of all existing cases, this very “hour X”, favorable for a full-fledged conception, lasts only one day, and these same days are called, as you probably already guessed, ovulation.

Directly on the day of full ovulation, which we will now teach you how to correctly calculate, a planned release of an already fully mature egg occurs directly from its house or follicle, which at the same time ruptures. And within 24 hours, this most mature egg that has emerged from the follicle will await its fertilization, and, unfortunately, if it turns out to be simply unclaimed, it will subsequently die, as Mother Nature intended this process to be. Horror, really, only 24 hours in a whole month, and even then all this in the most favorable best case scenario. Sometimes it happens that full ovulation does not occur at all. It should be noted that with a completely regular menstrual cycle and with the absolute health of the woman herself, on average, young women who never experience any gynecological or reproductive problems, only ten such ovulations occur per year, we can say that this does not happen monthly at all.

We will immediately try to warn those young and not entirely experienced girls who immediately decided to calculate their day of full ovulation for the sole purpose of protection, not everything is so simple. Remember, pregnancy will be very likely and quite possible if literally a few days before the onset of full ovulation you had poorly protected or even unprotected sexual intercourse. This can happen precisely because male sperm, unlike female egg, are always more tenacious, and they can retain their ability to fully fertilize even for several days, or rather up to one week.

In the same case, if you are trying to calculate exactly the opposite, then you, of course, should definitely know how to correctly calculate the day of your full ovulation.

How to correctly calculate your own ovulation?

Today there is a fairly simple, but quite effective formula that allows you to correctly calculate the day of full ovulation. Moreover, it is quite possible to do this even at home and without any additional equipment. Although, by the way, today there are already ready-made specially created calculators for calculating the onset of full-fledged ovulation online, which, of course, really simplify this task, but strictly speaking, there is absolutely nothing complicated or inaccessible in such manual calculations.

So, scientists have long established that the onset of full ovulation in any woman of reproductive age with almost any length of her menstrual cycle should occur exactly fourteen days before the first day of her next period. It should be noted that the duration of the very first phase of the menstrual cycle may well change somewhat, but the period after the onset of full ovulation is a completely constant value. And if, for example, your menstruation occurs quite regularly, as they say “number to number,” then, of course, calculating your day of full ovulation will be simply as easy as shelling pears.

Namely:

Your day of full ovulation will be equal to the date of your next period, from which you will need to subtract exactly fourteen days.

Let us give you a completely classic example: let’s say that with a woman’s regular and even accepted 28-day menstrual cycle, the onset of full ovulation usually occurs exactly on the fourteenth day of such a cycle. And if, for example, this month your period began on the third day, then in the same full 28-day menstrual cycle you will need to wait for the onset of full ovulation exactly on the seventeenth day, namely exactly fourteen days before the start of your next period. In the event that your specific cycle is slightly longer or shorter than accepted norm, then directly to the first day of your last menstruation you will need to add the duration of your specific cycle (for example, 26 or 30 days). In this simple way you will get your expected date of the next menstruation, from which you will again need to subtract exactly fourteen days, and as a result of this you will get the exact date the onset of full ovulation in this particular menstrual cycle.

And in fact, it is on this principle and the so-called calendar method of female contraception was once built.

Such a calculation of the onset of full-fledged ovulation is truly quite simple, but it still has one rather significant BUT. This method may be applicable only for those women who have a strictly regular menstrual cycle. Moreover, of course, one should take into account the full schedule, well, at least for all the last four or even six menstrual cycles, and therefore for the same number of months.

If, on the contrary, you are carefully trying to get pregnant and for this simple purpose you are looking for how to correctly calculate the day of full ovulation, then our next advice will be incredibly useful for you. Namely: if you have an insufficiently regular menstrual cycle, say, lasting from twenty-six to thirty days, your chances of a full one increase significantly if you have sexual intercourse regularly and every other day directly from the tenth to the eighteenth days of the menstrual cycle. After all, this is the very time of expected ovulation

The ovulation calculator may be wrong

As you understand, for couples who are actively planning their pregnancy, calculating the time of full ovulation is truly extremely important and necessary. However, it is this method, unfortunately, cannot be considered too highly accurate. The thing is that ovulation itself is a very labile process. And, of course, under the influence of a number of extraneous external or internal factors and even with a fairly regular menstrual cycle, the onset of full ovulation can radically shift in one direction or another. And this, in particular, may well lead to frequent stress, severe overwork, and even frequent colds, as well as some hormonal imbalances. And even moreover, in extremely rare cases, but still, the onset of full ovulation can occur even twice in one monthly cycle, which women should especially remember if they want to protect themselves from unwanted pregnancy.

And, of course, it is not at all possible that in any particular menstrual cycle the onset of full ovulation will not occur at all. In fact, this is precisely why modern experts strongly recommend using possible methods for exactly in the complex. And first of all, in such a complex it will be important to focus on your own feelings, and also be sure to keep a schedule for measuring basal body temperatures, and, of course, use a special one. And the most correct and accurate will, of course, be to carry out timely ultrasound examination, which will definitely be able to determine the time of full ovulation as reliably as possible.

It is known that the most favorable moment for conceiving a fetus is ovulation, which in most cases determines the first steps in planning offspring. However, doing it correctly and with a high degree of accuracy is not at all easy, and this process will require considerable patience and a period of three or more months.

The most accessible task is to calculate the day of ovulation in women who do not have serious pathologies and disruptions of the menstrual cycle. Making a calendar for them ovulation will pass according to the classical scheme, which involves daily measurement of basal body temperature.

This procedure takes a minimum of time, but still requires thoroughness and methodology. To chart your basal temperature, you need to put a thermometer into the rectum or deep into the vagina every morning, immediately after waking up for the first time, take the readings and write them down according to the current date in the notebook marked out for the chart. In the simplest way, by constructing a dependence curve, you can clearly determine the rapid drop in basal temperature, and then its sharp jump. It is this date that will be considered the most successful for fertilization. The only conditions this study is regularity. In addition, measurements should be taken at the same time in the morning whenever possible. It is prohibited to get out of bed, move, eat, drink or perform other actions that reduce the accuracy of the thermometer readings.

It is noteworthy that using a graph of changes in basal temperature, you can not only identify possible problems in the female body. If no obvious temperature changes are observed at all, we can talk about ovulation failure, which should be immediately reported to the doctor to further solve the problem. Too sharp and frequent ups and downs in readings or, on the contrary, a monotonous graph line may indicate the presence of certain problems that interfere with the desired pregnancy. Thus, the resulting graph of changes in basal temperatures can serve additional method diagnostics possible reasons infertility, if any.

In addition, the construction of such a graph is highly recommended for the procedure intrauterine inseminations. In combination with ultrasound data, such a schedule will become a good “assistant” to the doctor in determining the date of release of the egg, so that insemination is carried out at the most suitable moment for the female body.

As a rule, for initial research, three months of observation is enough for a woman to calculate her own ovulation calendar correctly and with due accuracy. In some cases of uncertainty, doctors recommend continuing their research to get a clearer picture. However, based on graphs constructed over three or four monthly cycles, it is already possible to draw initial conclusions about how high the probability of conception is on the days indicated in the observations made.

However, it is possible to calculate the day of ovulation in another way, which, in combination with the above, can provide much more accurate and reliable information. Women planning to have a baby in the near future are recommended to use online calculator ovulation, which allows you to calculate the most favorable calendar days for pregnancy with extreme ease and in a matter of seconds. Such a program in its simplest version makes it possible to calculate ovulation online, using data such as the first day of the last menstruation and average duration menstrual cycle. As a result, indicative dates of three upcoming ovulations. However, one should still remember that there is a significant error in its results.

Of course, these are simple arithmetic operations any woman can do it on her own, and at the same time receive her own ovulation calendar. A well-known trick is to subtract the number 14 from the average duration monthly cycle. As a rule, in a healthy woman, the duration of the cycle can vary from 22 to 34 days. The number 14 means the average duration of the luteal phase. However, the result obtained in this way will only be an approximate value, and it is advisable to always make allowances for these calculations.

More advanced types of programs, which are ovulation calculator, also ask for the start date of the penultimate menstruation and, possibly, the duration of the luteal phase. Data from not only the last, but also the penultimate menstrual cycle significantly increases the reliability of the calculations. It is known that what longer period time will participate in the research and analysis, the more accurate the results will be, based on which it is already possible to draw realistic and adequate conclusions about the day of ovulation and the most successful period for planning future offspring.

In addition, the luteal, or otherwise secretory, phase is not always the same for absolutely all women, which is not taken into account in simpler calculator programs. Since the duration of the luteal phase is healthy women can vary from 12 to 16 days, the use of this data greatly increases the accuracy of calculations, making it possible to calculate ovulation with the highest degree of probability. Since a period of the luteal phase that is too short or too long is considered a clear deviation from the norm, this fact is subject to detailed discussion with a specialist.

Of course, it should be remembered that any ovulation calculator can only give an approximate result, the reliability of which is accepted only for women who have good health. For women suffering from any chronic or inflammatory diseases affecting their reproductive health, the ovulation calendar is not at all easy to calculate. On the contrary, this question often results in a significant and, alas, not always easy removable cause. Most likely, similar problem may require lengthy and effective therapy, which aims to restore the health of the entire body. After all, such powerful factors as heredity, failures hormonal levels, the presence of problems with the endocrine and genitourinary systems can negatively affect women's health, depriving them, by and large, of the opportunity to determine the day of ovulation and, accordingly, to conceive a child in a timely manner. In this case, the woman urgently needs the advice and help of a competent specialist, who, most likely, can put the issue of improving the patient’s health in the first place, leaving it for later and more successful times.

That is why the ovulation calendar can be considered a kind of indicator women's health, instantly responding to all sorts of changes in the body and, alas, its possible problems, so its benefits are quite obvious both for serious women who are responsible for the issues of reproduction, and for qualified health workers who set as their goal active assistance in the birth of a new life.

The vast majority of women know about such a thing as ovulation. But not everyone knows how to calculate the timing of its onset. There are several ways to help you find out the cherished date in each new menstrual cycle. However, the easiest way to do this is to use an ovulation calculator: calculate the most suitable days better with his help.

To get the result, you must enter the date of the first day of your last menstruation, the duration of the menstrual cycle and bleeding. You also need to indicate how long the calculation is required. As soon as the data is provided, you will be able to see a graph indicating the expected dates of menstruation and days favorable for conception.

Decoding the result:

Days of menstruation

- Ovulation

Favorable days for conception

Hello dear blog readers. If one of you is not fully aware, why do it at all? I'll explain. The fact is that for fertilization this process plays an almost dominant role. You need to know the date of egg maturation in order to effectively protect yourself from an unwanted pregnancy, or to obtain this pregnancy. However, often “mere results” are not enough. That is why we will analyze in detail why and when the egg leaves the ovary, how to accurately calculate ovulation using different methods.

Physiological aspects

Ovulation is the process of the release of a mature egg from the ovary. This happens under the influence of neuroendocrine mechanisms different levels. This term means that a role is played in this nerve impulses and hormones. Without going into details, let's look at what happens in the body.

The menstrual cycle is counted from the first day of the previous one until the beginning of the next menstruation. As soon as the bleeding ends, the next follicle begins to mature in the ovary, containing a germ cell - the follicular phase of the ovarian cycle begins. Gradually, with the development of the egg, the level of sex hormones increases.

By the time of final maturation of the follicular formation in female body there is a peak level of estradiol (the most active subtype of estrogen). When this value is reached, the walls of the follicle begin to collapse - the ovulatory process begins, triggering the luteal phase. As soon as sex cell found herself “free”, she heads into the fallopian tube, where she is able to live for 24 hours, waiting for her sperm.

In place of the torn "receptacle" of the germ cell matures corpus luteum- this is, relatively speaking, the “yolk” that will nourish the fetus until the placenta forms. If conception does not take place, then the egg dies, and the corpus luteum regresses as unnecessary. Throughout the entire period of its “life,” it produced the hormone progesterone, which is designed to help the fertilized egg implant (introduce) into the wall of the uterus. It softens the endometrium (the inner lining of the uterus), makes it loose, and improves blood supply. But with the regression of the corpus luteum, this hormone becomes less and less. And the loosened epithelium can no longer become “tight” again. Therefore, as soon as the level of progesterone decreases critically and the level of estrogen increases, another menstrual bleeding begins - rejection of the uterine epithelium.

So, ovulation is the release of an egg from its “shelter”. This “action” occurs approximately in the middle of the cycle (for example, if the latter lasts 28 days, on the 14th day). The release of the germ cell from the follicle can take place on the 13th and 15th day, this is considered normal. But the fact is that that same corpus luteum always lives only 14 days (rarely ±48 hours), regardless of the duration of the cycle. This means that if it lasts 35 days, then ovulation will take place on the 21st day, and if it is 22, then on the 8th. An ovulation calculator can calculate the optimal date for conception based on these data.

But what to do if you don’t regular cycle? When one time there are five weeks between bleedings, and the other time it is three weeks? In addition, there are such concepts as early and late menstruation, which are deviations from the norm, but occur frequently. How to understand what is starting favorable time to start pregnancy?

Calculation of ovulatory date

There are many methods to help find out exactly when the reproductive cell will mature and be released. Among them:

• online ovulation calculator (calculate for conception suitable date easiest and fastest), essentially repeats the calendar method;
• temperature method;
• cervical method;
• symptothermal method;
• by ultrasound.

Test Methods:

• test strips;
• inkjet tests;
• using a microscope;
• "fern" method.

It should be noted that to achieve reliability of any of the listed methods, it is necessary to carry out measurements for at least 5-6 cycles. You can compare what data the calculator provides and how the body actually behaves.

Calendar method

In principle, it has already been described in the previous section. It can only be used by those women who can boast of having periods “just on schedule.”

Observation must be carried out for 6 “circles”. Need to lead menstrual calendar, clearly marking the start and end dates of bleeding. For analysis you need:

1. Reveal the most long cycle. You need to subtract 12 from its length in a day. Why this particular number? As already mentioned, the corpus luteum lives only 14 days. For the reliability of calculations and taking into account possible physiological variations, it is worth slightly “expanding” the possible period of its appearance. This will be the last day in this cycle when conception can take place.
2. Find the shortest cycle. Subtract 19-20 from the number. The calculation is as follows: for example, the cycle duration is 26. Of these, 14-15 are the luteal phase. This means that ovulation occurred on day 11. However, sperm can live in the vagina for 2-3 days. Thus, starting from 8-9 days and ending with 12 are days favorable for conception.

Basal temperature measurement

Basal temperature is “heating” internal organs in a calm state.
It is necessary to measure the temperature:

• in the rectum (acceptable - in the vagina and mouth);
• at least 5-7 minutes;
• daily (including during menstrual bleeding);
• at the same time;
• immediately after sleep, which lasted at least 3-5 hours;
• with the same thermometer.

In the follicular phase of the menstrual cycle, the temperature does not exceed 36.4-36.8°C. However, 12-24 hours before the separation of the egg from the follicle, it rises, sometimes by almost a degree! This occurs to stimulate the rupture of the follicular formation. And throughout the postovulatory period until the first day next bleeding stays at 37.1-37.5°C. The period of time from the beginning of the cycle until the third day after the temperature jump is considered fertile.

This technique is used mostly for contraception rather than for pregnancy planning. After all, ovulation is often “visible” after the fact, when it has occurred. And after the third day of rising temperature, pregnancy is not possible until the next cycle.

However, it is best to combine the method of measuring basal temperature and an ovulation calculator - you can calculate the days for conception more accurately.

Cervical method

The vagina and cervix are very “slimy” organs. The possibility of pregnancy depends on the presence of this natural secretion, local immunity, condition of the mucous membrane. The condition of cervical mucus greatly depends on the level of hormones in the body. The more estrogen, the more liquid secretion. Immediately after menstruation, it is almost gone, which is unfavorable for sperm. Then it appears, but thick, viscous, like glue. It is inconvenient for male reproductive cells to move through it; they feel like they are in a swamp. Gradually it becomes more liquid, and by the time of ovulation it is watery, slippery, reminiscent egg white. Here they swim straight to the uterus.

Symptothermal method

The most reliable of the above is... a combination of these methods. If you calculate the release date of the egg according to the calendar, monitor the temperature and the state of mucus for several months, you can learn to determine ovulation almost accurately. Thus, in order to achieve conception, you need to carefully monitor your body.

Ultrasound diagnostics

Ultrasound is one of the key methods research in gynecology. With its help, you can track the process of follicle maturation from the very beginning until the release of the egg. This is done by a doctor functional diagnostics, which records the size of all follicular formations in the ovaries. As the moment of release of the egg approaches, one of them should increase in size, so that it will soon rupture and turn into the corpus luteum.

If the doctor sees that none of the follicles are growing, then he is forced to state an anovulatory, “single” cycle. It is possible to diagnose:

• hormonal deficiency (the formation has already developed, but the cell does not come out of it);
• premature hormonal effects(corpus luteum begins to form even before ovulation);
• cyst formation (postovulatory follicle growth);
• and etc.

It is worth noting that the calculator is not able to provide anovulatory cycles and crashes. Therefore, if there are any abnormalities or suspicions of them, it is necessary to be examined using ultrasound.

Test Methods

Similar to tests for determining the level of hCG (pregnancy test), there are test strips for recording luteinizing hormone, which is responsible for ovulation. There are inkjet tests, as well as strips that need to be dipped into urine. They can show one stripe (ovulation is “far away”), “one and a half”, in the sense of one fuzzy (usually 2 days before and 2 days after the release of the reproductive cell) and two - “we are here”.

To use such strips, it is necessary to use the calendar method. You must first calculate the average cycle length, find the approximate date of the ovulatory process, count 3 days from it and start conducting tests.

As already mentioned, at the ovulatory moment the body contains the most a large number of estrogen for the entire cycle. To find out what the content of this hormone is, they use the “fern method”. It is necessary to apply saliva to the glass. On days when the hormone content is low, when drying, salt from the liquid is deposited in the form of randomly located points. But when high level estrogen (2-3 days before ovulation and 2-3 after), these points are systematized and resemble a fern leaf.

Today glass has been replaced by mini microscopes the size of a lipstick tube. It has an area for applying biological fluid, as well as an eyepiece in which the result is visible. The principle of operation is similar to the “fern” one. Interpretation is carried out using control drawings from the instructions.

Thus, you can use anything: ultrasound, test strips, ovulation calculator - calculating suitable days for conception is not a problem. It is useless to argue about which of the listed methods is more accurate: ultrasonic, of course. However, it is less accessible and requires regular and frequent visits hospitals. The test method is only slightly inferior to it. However, it is best to use a combination of several techniques. What to do if the cycle “jumps”?

Irregular cycle

How to calculate ovulation when irregular cycle? The optimal test method is a mini microscope. The costs will be minimal (one such device costs about 300-400 rubles), the “equipment” will last a long time, and it will accurately show ovulation. And if you conduct research every day, then it is impossible to miss it.

You can also use cervical method. Cervical mucus is one of the clear indicators of approaching ovulation, and it begins to change a few days before it.

But the temperature and calendar methods will be of little help, including a calculator, because even if you monitor your menstruation for a year, the calendar calculation of the date of ovulation will be purely approximate.

Conclusion

Thus, with a regular cycle - calculate the ovulation calculator for conception best time, can do it “at once”! To be sure that the calculation is correct, you can repeat it yourself, as well as use other methods. However, if you experience any problems with your cycle or suspect recurring anovulatory periods, be sure to consult your doctor.

Ovulation and conception calendar is a universal and fairly easy-to-use service designed to calculate the menstrual cycle and the most favorable period conceiving a child. Its main task is to help a woman determine the days of increased fertility ( ovulation), during which conceiving a child most likely. At the same time, thanks to the calculation of the so-called “ safe days», ovulation calendar allows her to avoid unwanted pregnancy without the use of any medications or mechanical contraception. In order to take advantage ovulation calendar and calculate your own menstrual cycle (favorable period conceiving a child), fill in all the fields of the form below one by one. Registered and authorized users of our Internet portal can save their personal ovulation and conception calendar in the "favorites" section personal account and return to it later.

Ovulation calendar and the most favorable days for conceiving a child

Ovulation- this is the process during which an egg that is mature and completely ready for upcoming fertilization leaves the ovary and enters the abdominal cavity and then goes into the lumen of the fallopian tube. It was during this period that the probability conceiving a child maximum and is estimated at approximately 33%, which, of course, should be taken into account when calculating ovulation calendar and a woman’s planning for an upcoming pregnancy. After ovulation the egg is capable of fertilization ( conception) for 12-24 hours, while sperm after ejaculation remain active for 2-3 (and much less often 5-7) days. Considering this fact, the possibility of a woman becoming pregnant the day before ovulation is approximately 31%, two days before - 27%, and three and four days before ovulation- 16 and 14% respectively. In the same time conceiving a child six days before ovulation or the day after it is unlikely and even practically impossible. Usually ovulation occurs between the 14th and 16th days of the menstrual cycle under the influence of estrogens and pituitary hormones.

Ovulation calendar and sign of conception

One of the most reliable and important signs of the onset ovulation and favorable period for conceiving a child are changes in cervical mucus women. First of all, under the influence of estrogens, the amount of secretions increases and their viscosity decreases. The next, no less important, sign of egg maturation should be considered a decrease in rectal (basal) temperature during ovulation and raising it the next day. At the same time, in order to more accurately calculate ovulation and conception calendar, it is recommended to take your temperature every morning at the same time for several months. Sometimes at the moment ovulation a woman feels pain in the lower abdomen, the nature of which can vary quite widely from weak and short-term to strong and very long-lasting. It should also be noted that on days ovulation Some women experience a peak in sexual arousal.

Ovulation and conception calendar is a diagram of the menstrual cycle, which marks the time of its beginning, end, as well as the ovulation. Full management calendar involves mandatory recording of periods of active sexual activity. Compilation ovulation and conception calendar it is necessary to start long before planning pregnancy in order to learn how to determine the moment as accurately as possible ovulation and become familiar with all the features of your own body.

Ovulation calendar and conceiving a child

Depending on the probability conceiving a child and time ovulation menstrual cycle ( conception calendar) can be conditionally divided into three phases: relative sterility, fertility and absolute sterility. The period of relative sterility begins from the moment of appearance bloody discharge and ends ovulation. During this phase, some difficulties with contraception may arise, since its duration sometimes varies within several days, even with a stable duration of the cycle as a whole. This happens due to the fact that periodically, depending on certain factors (external and internal), ovulation comes a little earlier or vice versa later.

The fertile phase begins from the moment ovulation and ends after 48 hours. At this time the probability conceiving a child as high as possible. As noted above, after leaving the ovary, the egg is capable of fertilization within 12-24 hours, the remaining half of the time is allocated to inaccuracy in timing ovulation. Following the period of increased fertility, the woman enters a phase of absolute sterility, during which conceive a child almost impossible. This period lasts until the end of the menstrual cycle and is about 10-16 days.

Ovulation calendar and calculation of the period of conception of a child

Majority modern women count on ovulation and conception calendar in order to bring the long-awaited motherhood closer. Others are building calendar to protect yourself from unplanned pregnancy. However, no matter what goals they pursue, when calculating the menstrual cycle (and ovulation calendar in particular) in any way there is always a possibility of error.

According to calendar method calculation ovulation a woman should record the start and end days of her menstrual cycles for at least six months. In order to determine your individual fertile period based on these data ( ovulation and conception calendar), it is necessary to subtract 11 from the number of days of the longest cycle (the last fertile day of the cycle), and 18 from the number of days of the shortest cycle (the first fertile day). So, for example, the most long cycle for a woman it is 32 days: 32-11=21 (the 21st day of the cycle is the last in the fertile phase). Her shortest cycle is 26 days: 26-18=8 (the 8th day is the first in the fertile phase). IN in this case the most favorable period for conceiving a child is the interval from the 8th to the 21st day of the cycle (13 days in total).

One of the best and more exact ways calculation ovulation and conception calendar child is a combination of the above methods, which is called the symptothermal method. It includes measuring basal body temperature, daily monitoring of cervical mucus and accurate calculation ovulation calendar and favorable period for conceiving a child calendar method.

Action of tests for calculation ovulation calendar based on the same principle as for diagnosing pregnancy. When interacting with a woman’s urine, two transverse lines appear on it, one of which indicates the normal performance of the test, and the second indicates an increase in the level of luteinizing hormone (LH) and the woman’s full readiness for conceiving a child. However, if the second line remains paler than the control line for several cycles in a row, this may indicate the absence of ovulation due to any disease (disease thyroid gland and hyperprolactinemia, obesity and wasting, polycystic ovary syndrome and infantilism, increased level FSH and reduced level estradiol, chronic stress etc.) and is the basis for contacting a doctor.
