How many days after menstruation do you need to protect yourself?


Almost all women are interested in the answer to the question "Can I get pregnant immediately after menstruation?". Why? It's simple: if pregnancy is excluded, then you can relax, have sex, without being protected and not afraid to “fly into”. Some couples practice sex during menstruation, because they are sure there is nothing to be afraid of; this month they will not see 2 stripes on the test.

How really? Need to be protected in the first few days after menstruation or not?

Menstrual cycle and pregnancy

These concepts are closely related. Monthly periods began, which means that a new cycle and the maturation of the egg cell began in the body. This period is called follicular and lasts 7-20 days. Why such a spread in numbers? Because the average value is taken, because the body of each of the women is individual.

To the note: a year in a healthy woman ovulation can be only 10 times and this is considered the norm.

Can I get pregnant immediately after menstruation in 1, 2 day

This question interests both those who are planning to become a mother and those who want to avoid the “flight”. In most cases, conception immediately after menstruation is impossible. But there are exceptions to the rule. Known precedents when it turned out to get pregnant for 2 days after menstruation.

Remember the duration of your menstrual cycle. Is he short, just 21 days? Then there is something to worry about. At 2-3 days after the cessation of menstruation, conception is possible, because the egg has time to mature.

In more than half of the female population (with a 28-day cycle), conception is possible only a week after the end of menstruation. Therefore, in 1-3 days after menstruation to conceive a child is unlikely to succeed. But on the 6th day the chances increase.

It is believed that the 13-15 day cycle is the best time for conception. If you consider that sperm live up to 7 days, and the egg after ovulation 24 hours (in some sources they write that up to 48 hours), you can get pregnant at 7-20 day after the end of menstruation.

Attention! In most cases, the week before menstruation and the week after them are considered safe periods for conception. Be sure to keep in mind that every woman has an individual body. By the way, failures in the hormonal system can lead to unwanted pregnancy.

How not to get pregnant immediately after menstruation?

If you take into account all the factors that can lead to pregnancy in the first week after menstruation, then you can not worry and quietly enjoy intimacy with your loved one without a condom or interrupted sexual intercourse. What you should pay attention to?

  1. Consider the duration of the menstrual cycle. If you have it for 21-22 days, you can get pregnant immediately after your period. So you need to be protected.
  2. If you have abundant and prolonged menstruation, lasting about 7 days, then there is a chance that the maturation of the egg can occur in the last days of menstruation. Conclusion: unprotected sex in the first days after menstruation is undesirable, you can get pregnant.
  3. With an irregular menstrual cycle (this is when the cycle duration in one month is 30 days, in another 28 or 35) it is difficult to calculate the day of ovulation, which means that it is impossible to know exactly when favorable days come for conception. If you have an irregular menstrual cycle, then in the first days after menstruation do not risk, protect yourself, if you do not want to get pregnant.

If you take into account all these factors, learn to correctly determine the day of ovulation, then have sex immediately after menstruation, you can, without fear of becoming pregnant. But still there is a tiny chance that conception will occur. Therefore, draw conclusions and decide for yourself whether you need to protect yourself in the first days after menstruation or not.

Advantages of the calendar method of contraception

The girl who monitors her cycle and observes its regularity, sooner or later thinks about how to start being protected by the calendar method. First, sex without a condom has a beneficial effect on female hormones. Couples who do not use condoms every sexual intercourse have a closer psychological connection.

Agree, this is important for a strong and long-lasting relationship. Secondly, no one can argue with the fact that the sensations of both a woman and a man change for the better during sex without a condom.

Finally, the calendar method provides relative safety for a woman’s health: she doesn’t need to spoil the vaginal microflora with spermicidal lubricants or take birth control pills.

Moreover, it is also economically advantageous: after all, the prices for condoms and other contraceptive methods do not please a young couple who like to have sex often and several times in a row. However, if you do not know exactly how many days after menstruation you can not protect yourself, then you can not guarantee 100% protection against unwanted pregnancy. Therefore, we will examine in more detail how to begin using this method of contraception.

Ovulation comes to each girl at different times, so you need to focus only on your body.

Determine the days of increased fertility

The body of each woman is individual, and therefore one cannot simply take and calculate on the calculator when there is ovulation. The calculation will be approximate, which is not suitable for planning women, or for those who do not want children yet.

Approximately ovulation occurs 11-18 days before the onset of the next menstrual period. Since the run-up days is large enough, you need to try to calculate ovulation as accurately as possible. Best of all helps determine the ovulation calendar method.

Its reliability is confirmed by years of research, and if everything is done correctly, the probability of becoming pregnant is minimal, less than 1%. So, for several months (better than a whole year), you will need to keep a menstruation calendar, in which you will record its start date and duration.

It is important to determine the fertile period - the maximum number of days in a month when your body is able to conceive. The beginning of the fertile period can be calculated as follows: take the duration in days of the shortest of the observed menstrual cycles and subtract 18 days from it. The end of the fertile period is calculated similarly, only the first indicator takes the longest cycle, from which you need to subtract 11 days.

This period will be a period of increased fertility, in which it will be necessary not to forget about protection or to abstain from sexual contact altogether. Some couples these days practice interrupted sexual intercourse, which is also not an absolute guarantee of protection from unplanned pregnancy.

Egg lifespan

Compared with the sperm in the vagina, whose life expectancy is only a few hours, their viability in the cervix is ​​much higher, up to three days.

And the viability of the egg - 24 hours after leaving the ovary. This period of time is called ovulation, after the day has passed since its beginning, the girl can no longer become pregnant. Thus, as soon as you find out that you have ovulation, you need to wait a day, and then you can have sex without being protected.

Once or twice a year, every woman has an anovulatory month in which ovulation does not occur, despite the presence of menstrual flow. Therefore, even if you did not consider how many days after your period you can not protect yourself and have sex on a “dangerous” day, this does not mean that you will become pregnant.

Who this method is not suitable for

From the calendar method should be abandoned women with irregular menstrual cycle. Until the cycle is normalized, the calculations can be considered invalid. Instead of taking the risk, it is better to use standard contraceptive methods or to purchase special tests at the pharmacy that determine ovulation.

Also, if the gap between the menstrual cycles of a woman is very small, and the man has surviving sperm cells, there is a possibility of conception even after intercourse during menstruation.

Why can I get pregnant during the first days after menstruation

Pregnancy a couple of days after menstruation occurs when a woman has:

  • the menstrual cycle is too short, that is, if it is less than twenty-one days, ovulation can occur within a few days after the bleeding, and since the physiological ability of spermatozoa to “wait” for an egg cell is great, it turns out that after unprotected sexual intercourse on the first day after menstruation you can get pregnant freely,
  • long menstrual bleeding with a short cycle,
  • unstable cycle, in this case it is almost impossible to calculate how long this or that phase lasts and when the organism enters the ovulatory period, there are cases when the egg matures immediately after the end of menstruation,
  • spontaneous ovulation, in the body two eggs mature at once, so the child can be conceived in this case during any period of the menstrual cycle.

The risk of unwanted pregnancy immediately after the end of menstruation increases and through possible diseases of the cervix. In this state of affairs, a woman may confuse uterine bleeding with menstruation, which means that during this period the body may be in the ovulatory phase, that is, the chances of pregnancy are high

And as a brief result, the female body is capable of conceiving on almost any day of the cycle, so you should not risk your health and act cruelly towards your future baby, and choose a more reliable method of contraception. Remember pregnancy should be if not planned, then desired.

How many days after menstruation can not be protected

The success of conception depends on a combination of different factors: when a woman has ovulation, how viable is her egg and partner spermatozoa. For the female reproductive cell, the maximum period of life is 24 hours, whereas for the male it is from 48 to 72.

Actually, ovulation - the period when a woman is able to conceive a child - occurs approximately in the middle of the cycle. Gynecologists believe that this moment falls on the period from 11 to 18 days before the first day of the next menstruation. That is, it is necessary to protect oneself during this period, and the rest of the days are theoretically safe.

In addition, the probability of conception is high if, during the period of viability of the male reproductive cell, it enters the vagina of a woman who must ovulate.

To determine the presence or absence of ovulation, you can use a special pharmacy test, but it will show only the result at the time of its use. And to calculate the period when unprotected sexual intercourse is acceptable and safe before menstruation or after them, the so-called calendar method helps.

Determining safe days using the calendar method

Many women, claiming that they cannot become pregnant immediately after their periods, do not take into account the time period in which they ovulate. Their statement is incorrect. Always this issue must be approached individually.

To use the calendar method and find out whether it is possible not to use the means of protection on certain days, a woman will have to carefully monitor her menstrual cycle. It is useful to take into account that it is more efficient to conduct calculations for at least 6 months, and preferably a year.

It is necessary to determine the longest and shortest cycles. For example, the cycle lasted the longest during this period for 30 days, and the least - 25. We count the possible safe days as follows: 25-18 = 7 and 30-11 = 19. It turns out that before the 7th and after the 20th day of the cycle there should be no pregnancy.

How to determine the days of increased fertility

You should always remember that the calendar method does not provide an absolute guarantee. Information about when you need to be protected most actively will not be completely true if a woman does not learn to determine the days of increased fertility, that is, a predisposition to conception.

A woman will be able to calculate the fertility days independently by setting up a basal temperature chart or examining the secretions of cervical mucus.

Measure the basal temperature should be daily for at least three cycles in a row. Indicators will be accurate if you take a measurement in the morning for at least 5 minutes without getting up, without changing the thermometer. Data must be recorded and dotted so that they can be combined into a graph.

If a woman's menstrual cycle is normal, this graph looks like a curve with an increase in temperature in the middle of the cycle by 0.2-0.6 C. When ovulation occurs, the indicator drops by several tenths of a degree. In the figure it looks like a clove pointing down.

Based on the temperature data received and plotted over a period of several months, a peak is determined. For example, this is the 13th day of the cycle. To designate the period of fertility, it is necessary to subtract 6 from it and add 4: 13-6 = 7 and 13 + 4 = 17. Stage of the cycle from the 7th to the 17th day and is suitable for conception. This way to find out if it is possible to become pregnant will not be effective if a woman is ill, takes hormonal preparations, has been subjected to stress.

The cervical method is the determination of the stage of the menstrual cycle according to the nature of the mucus that is released from the vagina.

In a woman who does not have gynecological pathologies, from the 18th day of the cycle before the menstrual period and from the 6th to the 10th day there are practically none. From 10 to 18 liquid mucus appears, like raw egg white. When ovulation ends, a thick secret stands out. After 3 - 4 days after the appearance of mucus, ovulation ends, which means that pregnancy is impossible. This method is not suitable for women with diseases of the cervix or vagina.

Why conception can occur immediately after menstruation

Women who want to know whether it is possible to protect themselves from an unwanted pregnancy using the calendar method, it is important to understand: doctors cannot give one hundred percent guarantee that there will be no conception. Moreover, even a protected woman can become pregnant.

Least of all calendar method should trust women, menstruation which is irregular. If a cycle fails, any calculations are wrong.

The hormonal system of a woman can in principle be disturbed at any time for various reasons. Often the hormone surge leads to early ovulation, and hence the possible fertile period shifts dramatically. Being engaged in unprotected sex before menstruation or immediately after menstruation, you need to remember that hormonal disruption could occur, but did not show itself, and the probability of conception increased significantly.


Every woman herself has the right to decide whether to take the risk and not protect herself. But she should be aware that the method of contraception, based on calculations of the time when the probability of getting pregnant is reduced before menstruation, can fail. This also applies to the assertion that immediately after menstruation it is impossible.

It must be remembered that ovulation is unstable, and sperm, trapped in the female genital tract, live up to 72 hours. Only a protective partner will help to become almost one hundred percent guarantee that an unwanted pregnancy does not occur.
