Pregnancy during menstruation


Many girls want to know if you can actually get pregnant during your period. This is an extremely important question. After all, someone uses the calendar method of protection to avoid the "interesting situation", but someone wants to quickly become a mother. When planning a baby, the menstrual cycle plays an important role. It depends on what days the girl can fertilize. What can be said about this issue? Further attention will be presented to the experts on pregnancy planning.

The menstrual cycle and its phases

Is it possible to get pregnant during your period or not? To correctly answer this question, you need to understand the features of baby planning.

A woman's menstrual cycle is the time between two menstruations. It consists of several phases. Namely:

Can I get pregnant during menstruation? The answer depends on complete randomness in relation to a particular woman, namely the phase of menstruation during which critical days come.

Follicular stage

To begin, consider each stage of the cycle in more detail. The follicular stage is the period when an egg cell matures and develops in the follicle. She is not yet ready for fertilization and is hidden in a special "shell".

At the moment, conception is impossible. Therefore, the risk of becoming pregnant during menstruation is minimal. The follicular stage of menstruation is its initial phase.

Is there a chance of getting pregnant during menstruation or not? Ideally, conception should occur during ovulation with a 100% chance. This stage occurs approximately in the middle of the cycle.

The egg cell is ready for fertilization and leaves the follicle, and then begins its journey through the body. The female cell goes through the fallopian tubes to the uterus. During this time, conception may occur.

The ovulation period is very small - it is only 48 hours. After this stage, the chance of becoming pregnant decreases. And by 3-4 days, going after ovulation, the risk of becoming a mother is not planned, is zero. In any case, a perfectly healthy girl.

Luteal phase

Can I get pregnant during menstruation? The third phase is called luteal. It occurs immediately after ovulation and lasts until the beginning of a new menstrual cycle.

At this time, the unfertilized egg cell dies. The body is preparing for a new menstrual cycle. The stage ends with critical days.

During this phase of the cycle, pregnancy is excluded. After all, the egg, ready to fully fertilize, in the body anymore. So, to become a mother at this time will not work.

Critical days and conception

Can you get pregnant on the first day of your period? Not. This is possible mainly during ovulation. The remaining days of the cycle are considered safe. And during them to become a mother will not work.

However, experts say that the likelihood of getting pregnant during your period is still there. It is minimal, but present. Although ideally fertilization of the egg is carried out in the ovulatory period.

Unsafe days

The risk of becoming pregnant during menstruation, as has been said, is the place to be. But this statement should not be understood directly. It is treated a little differently.

Unprotected sex during menstruation can lead to an unplanned pregnancy. This is quite common. Doctors confirm that any unprotected sex can lead to successful fertilization of the egg.

The thing is that the menstrual cycle can be divided into two types of days relative to conception - dangerous and not. As a rule, the absence of risks of successful fertilization of the egg falls on the luteal phase, 3 or more days after ovulation.

In this case, before the movement of the egg from the follicle, it is necessary to carefully treat unprotected sexual acts. After all, no doctor can say with confidence that critical days are a good method of contraception.

Short cycle

Is it possible to get pregnant immediately after menstruation? Yes, but the probability of such an event in healthy girls is extremely small.

The risk of an unplanned "interesting position" during menstruation and immediately after it exists in women with a short monthly cycle. Then ovulation can occur on 6-10 days after the start of critical days. Sometimes menstrual bleeding is not over, and ovulation is on the way.

Under similar circumstances, becoming a mother in the near future is really possible. Therefore, girls with a short menstrual cycle should be very responsible approach to issues of protection.


Can I get pregnant immediately after menstruation? Ideally, no. But nature decided otherwise. Under certain circumstances, girls are faced with ovulation immediately after menstruation. And therefore the risks of becoming a mother are maximal.

As we have said, there are safe days in relation to conception during the cycle, but risky time also occurs. They are calculated taking into account the longevity of sperm.

Ideally, male cells ready for fertilization will live in the girl's body for about 6-7 days. This means that unprotected sexual intercourse a week before ovulation can lead to a successful conception of a baby.

The inconstancy of ovulation

We found out why you can not get pregnant during menstruation. This is simply impossible, because the egg cell is not yet ready for fertilization. Conception of the baby immediately after menstrual bleeding occurs with a short interval between critical days.

Another problem when planning a baby is the inconstancy of ovulation. Ideally, it occurs in the middle of the loop. But external factors and diseases can accelerate or delay the "Day X".

Accordingly, doctors say that any unprotected sex can lead to pregnancy. And this is a valid statement.


You can not get pregnant during menstruation on day 3. But unprotected sex at this time can lead to a successful conception. Especially if the girl has a short menstrual cycle. If it is long, it is impossible to hope for successful fertilization during this period.

Sometimes a girl has anovulation. This is the absence of "Day X". Is it possible to become a mother under similar circumstances?

While there is anovulation, no. If a girl gets rid of this phenomenon, she can again become a mother.

Lack of ovulation can occur even under the condition of the established menstrual cycle. This is not the most common phenomenon, but it still occurs in real life.

What affects ovulation?

Getting pregnant during menstruation in real life is not possible. But unprotected intercourse can lead to unplanned fertilization.

As already mentioned, a variety of factors can affect ovulation. Namely:

  • stress,
  • overwork,
  • physical and mental stress,
  • alcohol / tobacco use,
  • acclimatization,
  • long journeys or flights,
  • hormonal medication.

In addition, a number of hormone-free drugs affect ovulation. Sometimes the girl thinks that everything is proceeding in the usual way, but in fact the “Day X” has already passed. Or it is still far away. Therefore, it is important to correctly determine ovulation. Only then can the girl deal with the planning of the child.

Childbirth, monthly and pregnancy

Special attention should be paid to newly born women. After childbirth, the women's cycle is lost. The body is facing strong changes and, therefore, planning the next baby can cause a lot of trouble.

The risk of getting pregnant with recently born girls is quite high. This is due to the fact that the cycle after birth gets off and begins to form again. Ovulation occurs unexpectedly. And no one can say for sure when to wait for the next menstruation.

A non-constant critical cycle lasts about 12–18 months after delivery. But longer periods of uncertainty are not excluded. Thus, everything will depend solely on the individual "settings" of an individual female body.

Oral contraceptive use

In some cases, women take oral contraceptives. For example, in the treatment of infertility or as protection from unwanted pregnancy. Is it worth worrying about conceiving under similar circumstances?

Yes. The thing is that you can get pregnant during your period when taking oral contraceptives. Rarely, but it happens. Immediately after the end of the reception of OC, egg maturation and ovulation are provoked. In some cases, similar processes are observed with menstrual bleeding.

It follows that reception of OK does not give any guarantees for the impossibility of conception during menstrual bleeding. So, protection should be taken very seriously. Especially if the girl does not want to become a mother in the near future.


Ideally, menstruation leads to the formation of an unfavorable environment for the life of spermatozoa. And so the male cells die quickly, not having time to wait for the right day for fertilization.

However, sometimes even during menstruation, you can encounter successful fertilization of the egg. Doctors claim that the calendar method of protection is not reliable. And sexual intercourse during menstrual bleeding does not give any guarantees for the lack of a successful conception of the baby.

It follows that for safer sex it is better to use condoms. Interrupted sexual acts, as well as making love during menstruation, have the risk of an unplanned "interesting position". Oral contraceptives can also fail in some situations.

From the above, it follows that on the first day of the “red calendar days” you can become pregnant only in exceptional cases. And ideally, the successful conception of a child falls on ovulation.

Sex during menstruation

For many, the frank fact that some young couples do not end their intimate life even during their monthly partners is shocking and causes some confusion. Many do not even understand the reason that prompts people to have sex during this period.

However, from a physiological point of view, the answer is simple: menstrual bleeding provokes a pretty strong sexual desire in a woman. Often, the partner is simply unable to contain him. By the way, men also have increased libido. However, the cause of this phenomenon is still not clear to medicine, perhaps it is a question of a surge in hormones.

Doctors insist that sex during menstruation is possible only in two cases:

  1. intimate relationship with a regular partner,
  2. confidence in the health of the partner and his lack of diseases that can be contracted during intimate intimacy.

The unpredictability of sex in the process of menstrual bleeding lies in the fact that the uterus of a woman these days is an open wound surface, the cervical canal opens slightly, which can lead to infection with dangerous diseases.

A bit of physiology: ovulation and the menstrual cycle

During each menstrual cycle, the ovaries in the woman's body secrete an egg. In medicine, this process is called ovulation. On average, according to statistics, ovulation occurs in the middle of the menstrual cycle, that is, on the fourteenth day after the first day of menstruation or two weeks before the start of the next menstruation.

However, to meet a woman with a perfect menstrual cycle, the duration of which does not change, is almost impossible. There are cases when ovulation is absent, but menstrual bleeding occurs.

After ovulation has passed, the egg moves through the fallopian tubes towards the uterus. Provided that during this period active, viable sperm got into the female organism, then the fertilization of the egg will take place right here in the fallopian tubes.

For the successful conception of the baby, fertilization should take place in the next day, otherwise the egg cell is removed from the woman’s body.

The ideal menstrual cycle, as a rule, consists of 28 days and is conditionally divided into three phases:

  1. The maturation of the follicle. The duration of this phase is 14-15 days. The first day of the phase is considered the first day of the onset of menstruation.
    From the medical point of view, the follicle is a component of the ovary containing the egg cell. Under the influence of certain hormones in the ovary, the follicle, that is, the egg cell, is maturing.
  2. Ovulation. When the maturation phase of the egg ends, it leaves the ovary into the abdominal cavity. After the egg gets into the fallopian tubes.
    The ovulation phase occurs at approximately 14-16 day of the menstrual cycle. The process of ovulation may be accompanied by minor pain in the lower abdomen from the side of the ovary in which the egg cell has matured.
  3. Luteal phase. The period that lasts after ovulation and until the end of the menstrual cycle. After the egg has left the ovary, the corpus luteum appears, which synthesizes the hormone progesterone.
    It is this hormone that blocks the maturation of other eggs during the luteal phase. If fertilization was not, by the end of the menstrual cycle, the corpus luteum decreases, and its functional ability fades away.
    As a result, the amount of progesterone and estrogen decreases, rejection of the outer layers of the endometrium occurs and bleeding begins.

Very often, a woman thinks about how to cause premature periods. What could be the reason for this? Meeting with a lover, a trip to rest and much more.

Not only medication can affect the menstrual cycle, but also with the help of bay leaf or onion peel. How to cause monthly folk remedies, read here.

The probability of meeting sperm and egg

Sufficiently long-term viability of sperm can cause conception to occur during menstruation.

The average lifespan of sperm is three days, but it should be borne in mind that in a favorable environment in a woman’s body this the period is extended to five days but there are exceptional cases where sperm are active for a week.

Thus, the spermatozoa trapped in the female body during menstruation, can wait for a favorable moment, that is, ovulation, and then the fertilization of the egg is quite possible. Especially if unprotected intimacy preceded ovulation or occurred immediately after.

It is important to remember that there is a chance to confuse real menstrual bleeding with vaginal bleeding. It occurs in the case of an unbalanced, unhealthy diet or injury to the cervix.

It is possible that ovulation occurs until the end of menstruation or its duration is several days after the end of menstrual bleeding.

To confirm or deny the fact of pregnancy after unprotected sex during menstruation or other kind of bleeding, it is best to use pregnancy test. However, there is a possibility that the test will be negative, although all signs indicate pregnancy. In this case, you must pass blood for level of hormone hCG, because its amount increases much faster in the blood than in the urine.

How high is the probability? Let's try to figure it out

The probability of pregnancy during menstruation is minimal if the woman has an ideal menstrual cycle, in which she is confident, and ovulation occurs every month in the same period.

Especially in the first days of bleeding, pregnancy is excluded, since during active bleeding, spermatozoa do not have the opportunity to penetrate into the female body. However, there are several factors that increase the likelihood of pregnancy during menstruation.

  1. Long period of menstruation in combination with a short menstrual cycle. In this case, doctors call a short menstrual cycle a cycle that lasts less than 25 days, and long periods of more than a week.
    As a rule, these women have a slight discharge, called "daub." It is these days there is a high probability of conceiving a child.
  2. Irregular menstrual cycle. In this case, we are talking about a cycle, the duration of which is crucially monthly. varies from 21 to 35 days.
    For women with such a cycle, the calendar method of pregnancy planning is absolutely not suitable. In this situation, the days of ovulation are also irregular and pregnancy may occur even in the last days of menstrual bleeding.
  3. Spontaneous ovulation. In medicine, cases have been described where, during a single menstrual cycle, a woman had two ovulations, therefore, the body produced two eggs with a short break of no more than three days.
    In this case, the first egg cell, as a rule, does not fertilize and leaves the body along with bleeding, while the second egg is quite viable and can be fertilized. Doctors call the reason for spontaneous ovulation a very strong orgasm during intimate intimacy.

  4. Other factors. Также следует учитывать, что на менструальный цикл и дни овуляции влияют и другие факторы: прием гормональных препаратов, стрессовые ситуации, заболевания организма, командировки, резкая смена веса тела.

Необходима ли контрацепция во время критических дней?

Undoubtedly, doctors advise the use of contraceptive methods even during menstruation. This is due to the fact that hormonal failure, provoking pregnancy, can occur at any time. Not a single woman is insured against such a turn of events, even perfectly healthy and with a regular menstrual cycle.

Doctors recommend using a condom as a method of contraception, which will help not only prevent pregnancy, but also create a reliable barrier against infections.
