Get pregnant during your last period. Is it possible to get pregnant on the last day of menstruation?

There is an opinion, both among guys and girls, that the likelihood of getting pregnant on the last day of menstruation, just like at the beginning of this period, is almost impossible. However, this statement does not fully correspond to reality, and if you turn to a gynecologist with this question, he will definitely answer that there is a chance of fertilization of the egg.

Moreover, almost every gynecologist can say that with good sexual health there are no moments at which it would be possible to have sex without contraception, and clearly understand that there will definitely be no pregnancy. Accordingly, if a woman does not intend to become a mother, it is better to refrain from such a contraception method as determining safe days. Let's take a closer look at whether you can get pregnant on the last day of your period.

It is worth saying that any sexual contact that occurs without the use of contraception, even if it occurred during menstrual bleeding, has a chance of resulting in pregnancy. In order to understand the cycle, it is necessary to understand the physiology of this process.

The main stages are considered to be follicular, ovulatory and luteal, with each of them playing a certain role in preparing the female body for bearing a fetus. In the first stage of the cycle, the production of follicle-stimulating hormone and estrogen is enhanced. The next stage is the process of maturation of the germ cell, after which it leaves the follicle and continues its movement into the uterine cavity through the fallopian tubes.

If at this moment the reproductive cell meets a sperm on its way, subject to unprotected sexual intercourse, fertilization will occur. The lifespan of an egg does not exceed one day; it is at this time that there is a maximum probability of conception. Therefore, answering the question, in the last days of your period, is it possible to get pregnant, it is worth saying that there is a possibility.

The ovulatory phase occurs approximately in the middle of the cycle, after the woman’s reproductive cell is fertilized or dies, the final stage begins in the body, called the corpus luteum stage. At this stage, follicle-stimulating hormone and progesterone are activated, because they are responsible for maintaining pregnancy and implantation of the fertilized egg into the uterine cavity.

If fertilization does not occur, then the dead egg is released during menstrual bleeding, and the corpus luteum itself dissolves by the beginning of the next menstruation.

Favorable periods

After the ovulatory period has begun, conception can occur within two days, which is exactly the lifespan of the egg. Accordingly, depending on the characteristics of the cycle, you can get pregnant on the last day of your period if you have unprotected sexual intercourse.

If you answer the question, on the last day of your period, what is the probability of getting pregnant, it is worth saying that doctors do not give specific numbers. The fact is that throughout the entire period while the egg is in the reproductive tract and the sperm penetrates it, conception occurs in most cases.

As for the lifespan and the ability to fertilize, experts here call the period from two to seven days, which directly depends on the somatic health of the sexual partner, his lifestyle and the presence or absence of bad habits. In situations where the most favorable conditions are created to preserve all the abilities of the sperm, it can fertilize the egg in the woman’s genital tract within 7-10 days.

On average, a woman without pathologies experiences the onset of ovulation approximately on the 14th day of the cycle, based on this, we can say that conception on the last day of menstruation is likely if they occur on days 7-16. However, the opinions of doctors regarding this method of calculating favorable days for conception differ.

The majority believe that it cannot be called correct, much less used as a method of contraception, defining periods during which it is impossible to get pregnant. The human factor cannot be discounted, because at any moment the cycle can go wrong, for example, after taking any medications or suffering from an illness, then it is definitely possible to get pregnant on the last day of your period if you do not use protection.

Predisposing factors

Many girls wonder on the last day of their period whether it is possible to get pregnant, and doctors unanimously assure that it is unacceptable to have unprotected sex life during menstrual bleeding if conception is not planned. There are also certain predisposing factors that increase the likelihood of fertilization.

First of all, you need to pay attention to the intensity of the discharge, as well as the individual duration of the cycle. For most women, standard calendar schemes for determining dangerous and safe days for conception are not suitable.

On the last day of your period, getting pregnant is extremely likely if the girl’s cycle lasts about 21 days. However, it should not be ruled out that with a standard cycle length and unprotected sexual contact with a partner on the last day of bleeding, conception will not occur.

If you do not want another early pregnancy, doctors advise women who have recently given birth to a child to approach sex with special care. The fact is that after labor, the body is greatly rebuilt, and, accordingly, the previously established cycle undergoes changes. Doctors, answering the question whether it is possible to get pregnant during menstruation in the last days, answer in the affirmative and positively.

There are situations when several eggs mature in the body during one cycle, which is called spontaneous ovulation, then the likelihood of getting pregnant at the end of menstruation also increases.

Probability of pregnancy

Gynecologists note that it is the first day of menstrual bleeding that is marked by the minimum level of probability of conception, even if sex was unprotected. It is also worth saying that fertilization most likely will not happen if ovulation was late and the egg matured immediately before the start of discharge. The fact is that sufficient bleeding will not allow the sperm to penetrate the oocyte.

The majority of women are almost completely sure that the conception of a child occurred on the first day of menstruation, but since physiologically this is almost impossible, experts assure that fertilization occurred shortly before the onset of discharge during late ovulation.

Long and short cycle

Is it possible to get pregnant during menstruation in the last days? Almost every woman is interested. First of all, it must be said that the fertilization process depends not only on the vitality of sperm and the readiness of the egg, but also on the duration of the cycle. In the case of such a time ratio as 3 days of discharge and a 28-day cycle, we can talk about a short period.

Under this set of circumstances, the likelihood that a woman becomes pregnant at the end of her period is extremely low, since on average, ovulation in such a cycle will occur no earlier than 10 days later. However, for those girls who have a discharge lasting from a week to 10 days, then we can talk about prolonged menstruation. In this case, the probability of pregnancy is high, since after the end of menstruation the ovulatory period begins almost immediately.

It is considered normal when a woman’s regular bleeding lasts from 4 to 6 days, with ovulation often occurring no later than the eighth day. In this case, if intimacy without contraception occurs on the 5-6th day, then the answer to the question: is it possible to get pregnant on the last day of your period will be definitely yes. Considering the lifespan of a sperm, even if the release of the egg is late, there is still a chance of fertilization.

As for the longer cycle, which is about 35 days, in this case the egg matures on 20-22 days, taking into account the lifespan of sperm in the female genital tract, which, under favorable conditions, is from 7 to 10 days, the most likely period of conception will be Days 10-22 of the cycle. Accordingly, when wondering whether it is possible to get pregnant on the last day of your period, you should understand that conception is unlikely.

It turns out that the probability of getting pregnant on the last day of menstruation depends on the length of the cycle, the number of days of menstrual bleeding and the viability of the sperm of a particular sexual partner.

How to avoid pregnancy

Currently, the pharmaceutical market offers a wide range of different contraceptives, which differ in composition, method of use and gender. If a woman is not going to become a mother in the near future, then she should take care to prevent conception.

So, most girls prefer oral contraceptives. Their advantage is that when used correctly, the cycle becomes clear, and menstruation comes almost to the hour. Among the disadvantages, it is worth noting the need to regularly take pills at certain hours.

In a situation where unprotected sex occurred and ejaculation was in the vagina, or there was interrupted sexual intercourse, you can take emergency contraception. The effect of medications is entirely aimed at preventing ovulation in a woman’s body. It is important to understand that such drugs are strictly unacceptable to take on an ongoing basis, since they greatly affect hormonal levels.

As for oral contraceptives, they are also hormonal, so they should be selected together with a gynecologist, and only after a thorough diagnosis of the body. When taking such medications regularly, the contraceptive effect continues during the seven-day break.

Doctor's opinion (video)

Many couples practice. At the same time, they are confident that these days are safe for conception. The most appropriate time for sex is at the end of the discharge. During this period, the bleeding itself is already decreasing, which, from an aesthetic point of view, is most comfortable. During this period, many women experience increased sexual attraction to their partner, which also encourages contact. In order to avoid unwanted pregnancy, every couple should consult with their doctor on the topic: “Is it possible to get pregnant on the last day of your period?”

“The last day of your period, is it possible to get pregnant during this period?” – a question that interests many. Before we begin to examine it in detail, it is worth talking about the physiology of the weaker sex.

Every woman's menstrual cycle consists of two phases. The first begins with the appearance of menstruation. During this period, the ovary forms a follicle where the egg will mature. The process is controlled by estrogen with its “helpers”: follicle-stimulating hormone and luteinizing hormone. Under their influence, not only the ovaries, but also the uterus change: the endometrial layer thickens significantly, blood circulation increases, and the organ prepares for the implantation of the fetus. The duration of this phase with a cycle of 28 days is two weeks. It ends with the rupture of the follicle and the release of the female reproductive cell into the fallopian tube.

After ovulation, the luteal phase begins. The corpus luteum begins to function in the ovary, producing the hormone progesterone, which is responsible for pregnancy. At this stage, the egg moves through the fallopian tube, where the fertilization process itself occurs. After the fusion of male and female cells, the zygote moves into the uterine cavity and penetrates into the endometrial layer. If the sperm does not fertilize the egg within two days, it will die and further disintegrate. This is followed by endometrial detachment, and menstruation begins. This concludes the second phase.

No one can answer for sure what the probability of getting pregnant on the last day of your period is. It is definitely possible to conceive a child during menstruation, especially at the end of it. The fact is that during this period the amount of bloody discharge is reduced to a minimum, and this allows sperm to reach their target without obstacles.

Another fact is that male reproductive cells can live in a woman’s body for up to ten days. If sexual intercourse without the use of barrier contraception was at the end of menstruation, and new ovulation occurred a week later, it is quite possible to get pregnant.

When is pregnancy possible on the last day of menstruation?

Cases of conceiving a child during menstruation are very rare, but they do happen, because the human body is unpredictable. The following factors may contribute to this:

menstrual cycle disorders;
hormonal instability;
maturation of two eggs at once.

The main reason that can contribute to fertilization on the last day of menstruation is an irregular menstrual cycle. Such disruptions are usually caused by hormonal imbalances or infrequent sexual activity. In some women, follicle maturation occurs in just 7–10 days. And if we take the average duration of menstrual flow as 5–6 days, then unprotected sexual intercourse at the end of menstruation will lead to pregnancy. The likelihood of fertilization also increases due to the fact that sperm live for more than a week.

The second factor may be the formation of two mature eggs in one month. If they ripen, come out at the same time and are not fertilized, menstruation begins, there is no need to worry. But there are times when female cells prepare for fertilization within a few days of each other. In such a situation, the egg that matures first is released and is not fertilized, and accordingly, menstruation begins.

A few days later, just at the end of the bleeding, ovulation occurs again. In this case, you can get pregnant, and nothing prevents this: the cervix is open, there is practically no discharge, this makes it possible for sperm to easily enter the fallopian tube and fertilize. True, the likelihood that the zygote will subsequently penetrate the endometrium and the pregnancy will develop well is small, since the uterus has not had time to prepare. This becomes possible only with an irregular cycle.

How to prevent pregnancy on the last day of your period

Based on the foregoing, it becomes clear that relying on the calendar method of contraception is by no means worth it, since it does not provide a 100% guarantee.

To be calm after sexual intercourse and not worry about an unwanted pregnancy, you need to use barrier methods of contraception. In this case, a condom will not only protect the woman from pregnancy, but will also protect the man. When having sex without it, blood from the vagina may enter the partner’s urinary canal, which will subsequently lead to the development of an inflammatory process. Well, of course, using the barrier method will prevent both partners from becoming infected with sexually transmitted diseases.

If unprotected contact occurs, you need to resort to emergency methods of contraception.

These include hormonal pills, which are divided into two groups: gestagens and antigestagens. As for the former, they are safer for a woman’s body and can be taken without a doctor’s prescription. The peculiarity is that the tablet must be taken no later than 72 hours after the act.

The second group of drugs is more aggressive; their use must be under the supervision of a doctor. Such drugs are used to terminate pregnancy at a later stage of up to seven weeks.

Emergency contraception should not be used frequently; this can have a detrimental effect on a woman’s health and cause serious hormonal imbalances. It's best to think about this in advance.

In fact, many couples actively have sex during menstruation, being one hundred percent sure that they have nothing to fear, and it is simply impossible to get pregnant during this time. Quite often, a girl’s sexual activity only increases during this period, and thoughts about possible conception do not enter her mind at all. But as medical practice shows, more than one hundred children are born to such parents. How is this possible? And what you need to do to avoid getting pregnant during menstruation, especially in its last days.

A little physiology

Pregnancy is the result of the meeting of a sperm and a mature egg. Conception can occur only on the day of ovulation and within a couple of days after it. This period is a rather short phase of the menstrual cycle, during which an egg that has matured and prepared for possible fertilization leaves the ovary and moves to the uterine cavity. Every young and completely healthy girl ovulates once every three to five weeks.

Most of the fair sex firmly believe that these days fall in the middle of their menstrual cycle. This term refers to the time interval between the beginning of the last menstruation and the first day of the next. So, in the standard, with a menstrual cycle lasting four weeks, ovulation occurs around the fourteenth day. The life of a mature egg is short - literally a couple of days, after which it dies and leaves the body. Menstruation begins, lasting on average four to seven days.

Simple mathematical calculations confirm that pregnancy with such a menstrual cycle cannot possibly occur during the next menstruation. It seems logical that conception can only occur with active intimate life before or after menstruation. That is, we can conclude that conception during menstruation is impossible?

Options for conceiving during menstruation

Gynecologists are absolutely sure that you should not rely on menstruation and perceive it as a means of contraception. This can end completely unexpectedly: an unplanned pregnancy.

Each representative of the fair sex has her own individual menstrual cycle. If its duration is short - about twenty days, then the most dangerous days of possible conception fall precisely on the last days of menstruation. But even if ovulation occurs in the first days of the cycle, immediately after the cessation of menstruation, keep in mind that sperm can remain viable for up to five to seven days, and under a successful set of circumstances, sex during menstruation can result in pregnancy.

In addition, a woman should take into account that the normal ovulation rhythm can change after childbirth, as well as after an artificial termination of pregnancy. The time of egg maturation can also change in the period preceding the onset of menopause - after reaching the age of forty.

Doctors also say that one of the reasons for conception during menstruation is spontaneous ovulation. In this case, a pair of eggs matures per cycle. This situation can be provoked by various factors, for example, a strong orgasm, an unexpected hormonal surge. Sometimes the likelihood of a pair of eggs maturing is passed on through genes.

At what period of menstruation is conception most likely?

In the first days after the start of menstruation, the conditions for conception are not favorable enough. At this time, heavy bleeding develops, so sperm often do not reach the uterine cavity. And few couples have sex at this time, for the same reasons.

Some women can be sure that their pregnancy occurred on the first or second day after the start of menstruation. However, in most cases, conception occurred earlier, and minor bleeding, which is quite common in the initial stages of pregnancy, was mistaken for menstruation.

So, we can conclude that the last days of your period are often quite a good time to conceive. At this time, the discharge is not so intense and does not interfere with partners. If menstruation is prolonged, or if it is already irregular, then the likelihood of pregnancy increases several times.

This is why experts insist on using contraceptives during menstruation. A couple can choose condoms, pills or a coil.

Is it possible to get pregnant while taking the pill?

Remember that no contraceptive can protect you one hundred percent from unwanted pregnancy. However, correct use of the pills almost completely eliminates the possibility of conception, including in the last days of menstruation. However, if you skip a dose, use additional medications (antibiotics, sorbents, etc.), diarrhea or vomiting, you should use additional contraception. In addition, it should be taken into account that the effectiveness of oral contraceptives may be reduced by alcohol consumption. Correct use of such drugs can reduce the likelihood of conception to almost zero.

Menstruation does not guarantee you protection from unwanted pregnancy, so do not forget to use additional contraception even on these days.

Women's websites and forums are full of questions like: “is it possible to get pregnant at the very end, that is, on the last day of your period?” Many people believe that this is impossible, but modern medicine has a different opinion, namely: there are no safe days for a woman to conceive, so the likelihood of conception in the presence of spotting exists.

Is it possible to get pregnant on the last day of your period: gynecologists answer

What do gynecologists say about the likelihood of getting pregnant on the last day of your period?

There are days when the likelihood of conceiving is minimal, but it does not disappear completely. Therefore, if unprotected sexual intercourse occurs, fertilization of the egg is possible even when menstruation ends.

If you think that there is no chance of getting pregnant at the very end (last day) of your period, then you are mistaken. To protect yourself from unwanted pregnancy, you need to use additional contraception (condoms).

If your menstrual cycle is unstable, the antenatal clinic advises using oral contraceptives. They stabilize the cycle, and the woman gets an idea of its duration.

Often women use the calendar method as protection against fertilization, believing that it is impossible to get pregnant in the last days of the cycle and during menstruation. In this situation, everything depends on the individual characteristics of the body and the menstrual cycle.

It is best to avoid intimacy during menstruation

Most couples abstain from sex until their periods have ended. But regular partners practice contact already on the 3rd day of the cycle, without waiting for the end of discharge, the abundance of which is already minimal. And here the fair sex has a question: is it possible to get pregnant if sexual intercourse occurs at the end of your period?

To dispel all questions and misconceptions, you need to look at the statistics. There is a concept called the Pearl Index. It shows the effectiveness of various methods of contraception, as well as the number of unplanned conceptions on so-called “safe days”. It clearly shows that when using the calendar method, there is a chance of getting pregnant at the end of the critical days.

Fertilization process

At the moment of ejaculation, millions of sperm are released, and only one is the lucky one to fertilize the egg. Sperm remain viable for 5-7 days, so the chances of getting pregnant increase if sexual intercourse occurs at the moment when ovulation occurs.

In short, the fertilization process goes like this:

a mature egg must meet sperm;
sperm begin to fight for the right to fertilization, actively making their way through the protective layers of the egg;
Having penetrated inside, the winner tightly merges with the egg;
a cortical reaction occurs;
the losing sperm die.

There are often cases when several embryos develop as a result of fertilization. This is possible from either one or a pair of eggs. Identical twins develop from a multinucleated cell that is fertilized by several sperm at once. Fraternals appear as a result of fertilization of two eggs at once.

Fertilization is possible only if ovulation occurs. It occurs approximately in the middle of the cycle. This is a complex physiological process in which a mature egg is released from the ovary and “travels” through the fallopian tube waiting for a meeting. Its fusion with the sperm occurs within the first day after the start of the “walk”.

Each woman is created individually

To know for sure whether you can get pregnant with the last drops of your period, you need to know the time of ovulation. It is individual for each woman and largely depends on the duration of the menstrual cycle.

Normal cycle length

The female reproductive system operates in cycles. Cycle length varies from 20 to 35 days, and bleeding lasts from 3 to 10 days. The action of the cycle consists of the hormone estrogen, as well as gonadotropin, FSH (follicle-stimulating hormone), LH (luteinizing hormone), progesterone.

The normal cycle length is considered to be 28-30 days. The release of the egg in this case occurs approximately on the 14-15th day. If conception does not occur within 1-2 days, she dies.

If there was no sex during ovulation, but it happened a few days earlier, and there are viable sperm in the woman’s body, there is a possibility of conception.

Do not write off hormonal imbalances, in which the ovulatory period may occur earlier or later than usual. That is, there are no safe days, and it is quite possible to get pregnant during your period in the last days, although the chances are low.

Short menstruation and chance of fertilization

The probability of fertilization during critical days depends on their duration. With short menstruation, blood flow lasts 3 days.

The girl’s suffering is familiar to many women

Is it possible to get pregnant not during menstruation, but on the 10th day of the cycle? If unprotected sex occurs on the third menstrual day, and ovulation occurs 7-10 days after that, then this is quite possible.

Long periods and the likelihood of conception

If the discharge lasts 7-10 days, we are talking about long periods. In such a situation, even with a scanty smear, you can get pregnant at the end of your period.

This happens when sexual intercourse occurs on days 7-10 of the cycle, just when menstruation ends. After just a couple of days, the ovulatory period begins, and there will be enough sperm to fertilize the egg.

The most favorable days

To calculate safe days during menstruation, when the risk of fertilization is minimal, it is necessary to keep a menstrual calendar throughout the year.

the duration of the cycles is added up;
the resulting number is divided by 12;
the average cycle duration is obtained;
takes into account the fact that sperm can live in the vagina for up to 10 days;
It is taken into account that the most successful days for conception are 8 days before ovulation and 48 hours after its onset.

It turns out that the most favorable days for conception are the week before ovulation and 2 days after it (10 days in total). The remaining days are considered “safe”.
It is worth considering that this method more or less works only if there is no irregular cycle.

Safe days for PAP

Coitus interruptus (COI) is a popular method of pregnancy protection when the partner stops intercourse immediately before ejaculation. Despite its prevalence, PAP is not a good method of contraception. All gynecologists agree on this. There are no safe days for PAP. Why?

Becoming a mother is a woman’s main destiny

Even during interrupted intercourse, sperm penetrate into the woman’s vagina and are released along with the pre-seminal fluid in the man.

If you decide to use this method of preventing unwanted pregnancy, practice it only on those days when the likelihood of conceiving is minimal: a few days before menstruation.

During menstruation, the PPA method is not recommended. And not even the ability to get pregnant is the main reason. There is simply a high probability of infection entering the uterus, so it is better to use barrier methods of contraception.

How to avoid fertilization at the end of menstruation?

Doctors do not advise women to have intimacy during menstruation based on personal hygiene rules. But since at the end of menstruation the discharge is light, many women practice sexual intercourse. At the same time, they are sure that it is impossible to get pregnant, and there is no need to use protection. It is these women who are more likely to experience unplanned pregnancy.
If a couple is not yet ready to have a child, they need to know the phases of the menstrual cycle, the safest periods, and also take care of contraceptive methods so as not to suffer later, whether pregnancy is possible if unprotected intercourse occurs.

Most people use condoms or oral contraceptives during menstruation. Hormonal drugs are good because, together with protection against fertilization, they normalize a woman’s cycle.

You can also use emergency contraception, which includes the following drugs:

Mifegin;
Postinor;
Mifepristone;
Gynepristone;
Agest;
Escapelle.

These drugs are taken within 3 days after unprotected sex, their action is aimed at preventing ovulation and preventing the implantation of a fertilized egg. It is impossible to use emergency methods too often, as they negatively affect a woman’s health.

Is it possible to get pregnant during a short or long cycle?

An unstable, short or long cycle can cause you to become pregnant on the last day of your period. Causes of pregnancy in these cases:

short monthly cycle. Ovulation can occur on the 3rd day of bleeding, when the cycle duration is less than 20 days;
heavy menstruation lasting longer than 1 week. The release of the egg occurs immediately after the end of menstruation;
unstable cycle. It is impossible to calculate the day of ovulation or it occurs on the last day of the cycle, then the probability of conception even on the first day of menstruation is quite high;
double ovulation. In many women, not 1, but 2 eggs mature at once. It is difficult to determine at which phase of the cycle each of them will mature and which will be fertilized;
intrauterine pathologies. They provoke bleeding, which a woman mistakes for menstruation and gets confused in her calculations;
cycle failures. The same woman can have different cycles. Most often, disorders occur due to stress, weather changes, and hormonal imbalances. Ovulation occurs earlier or later than usual. Sometimes the fertilized egg attaches so tightly to the walls of the uterus that menstruation occurs during pregnancy. This, by the way, is the answer to the question of whether it is possible for menstruation to appear in the early stages of pregnancy.

Prevents the possibility of getting pregnant

Pregnancy symptoms

The first signs of pregnancy are different for each woman. At the initial stage, they are often ignored or confused with PMS symptoms. The initial symptoms are:

fatigue;
feeling of heaviness in the lower abdomen;
aching pain in the lumbar region;
decreased or increased appetite;
nausea;
increased sense of smell;
breast enlargement and tenderness;
bloating;
sudden mood changes.

If a woman is at least a week late and notices symptoms, she needs to take a pregnancy test.

If you decide that the time has come and it’s time to have a child, you shouldn’t rely on luck. Start preparing early. For this:

get your blood and urine tested to make sure your health is good;
undergo an examination: therapist, gynecologist, endocrinologist, dentist;
eat right, this is the key to the health of the mother and the unborn child;
take a course of vitamins, folic acid and vitamin E are important;
get rid of bad habits;
heal your body: walk in the fresh air, exercise, avoid stress.

With mood swings

Every representative of the fairer sex is concerned about the issue of conception. Women of reproductive age worry about whether they can get pregnant in the last days of their period. The answer to this question can be obtained in the gynecologist's office. This article will also tell you about the likelihood of getting pregnant on the last day of your period. Several individual situations will be considered. Absolutely all representatives of the fairer sex need to have an understanding of menstruation, ovulation and the process of conception. This will help you better understand your body and avoid many problems and unexpected situations.

Is it possible to get pregnant in the last days of your period: expert opinion

Experienced doctors, obstetricians and gynecologists say that conception can occur any day. If a woman is of reproductive age, then only the probability of getting pregnant changes during the cycle. The timing and probability of conception will be as follows. In the first half of the cycle, the possibility of fertilization is quite high. The probability increases as the cycle approaches its midpoint.

Is it possible to get pregnant in the last days of your period? Absolutely yes. Doctors say that there are no absolutely safe days. The probability of conception decreases on some days, while on others it increases. It is always worth remembering the viability of male cells - sperm. Under favorable conditions, they can remain in a woman’s body for up to ten days. Also, to get an answer to the question posed above, it is worth considering the duration of the menstrual cycle of the fairer sex.

Normal average cycle

Is it possible to get pregnant in the last days of your period when the female period lasts four weeks? It is 28 days that are considered the average statistical norm for the duration of the cycle. What is the probability of such a woman getting pregnant? It all depends on the duration of menstruation. Let's consider several situations.

Short menstruation and conception

If the duration of bleeding in a 28-day cycle is approximately 3 days, then we are talking about short menstruation. If sexual intercourse occurs on this day, and ovulation occurs 10 days later, then the probability of conception will be very low, but the possibility of this outcome cannot be completely excluded.

Long menstruation and the likelihood of fertilization

If bleeding lasts 7-10 days in a 4 week cycle, what is the chance of getting pregnant on the last day of your period? Sexual contact that occurs on the tenth day can lead to conception occurring on the day of ovulation - after 3-4 days. At this time, sperm will wait in the uterus and fallopian tubes of the woman.

Short cycle: three weeks

The days when you are most likely to get pregnant are during ovulation. Also, a few days before this are considered fertile. If a woman has a short cycle, the duration of which does not exceed three weeks, then what is the probability of conception on the last day of menstruation?

Normal bleeding lasts no more than six days. Ovulation in a short cycle lasting 21 days occurs approximately on the 7th-8th day. If sexual intercourse takes place on the 5-6th day of menstruation, then the probability of fertilization will be very high. Even if the follicle ruptures a little later than the expected date, the sperm can successfully wait their time in the cavity of the reproductive organ.

Long cycle and likelihood of conception

You already know the days when you can get pregnant. What can we say to those representatives of the fairer sex whose menstrual period is more than four weeks? It is worth noting that normally the cycle can last up to 35 days. In this case, the release of the egg from the follicle occurs approximately 20-21 days. If we take into account the fact that male gametes live in a woman’s body for about a week or even 10 days, the conclusion will be as follows.

Fertilization and subsequent pregnancy can result from sexual intercourse, which occurs between the 10th day of the cycle and until ovulation. This means that contact that takes place on the last day of menstruation has virtually no chance of conception occurring. However, this method of calculation and such a long cycle does not provide you with a guarantee that you will avoid pregnancy. Gynecologists always tell their patients about this.
