How to calculate when you can get pregnant. When can you get pregnant after menstruation

There is a possibility, use the calendar of your menstrual cycle. If you mark the date of the first day of menstruation every month, then it will not be difficult for you to lengthen the cycle. Count the number of days from one mark to another during the year. When your body is working properly without hormonal disruptions, then you get the same number in each period. Divide this number in half and find out the day of ovulation. For example, calculating the ideally correct cycle, which is 28 days, the date of ovulation - get 14 days.

After ovulation, the life expectancy of the egg is about a day - at this time, pregnancy occurs. However, there are times when one menstrual cycle two eggs are released from different ovaries or after withdrawal hormonal contraceptives several of them are released, so days probable pregnancy increase.

You can determine the days favorable for pregnancy with special ovulation test strips. They determine the increase in the level of luteinizing hormone in the urine. Start using the strips every day right after your period, preferably at the same time. Positive two strips, and you will know exactly the day of ovulation - the period when there is maximum probability get pregnant.

Scientists have calculated how many days a year a woman can go from normal to pregnant. It turns out, in fact, there are not so many days when a woman has a chance to conceive a child. Experts estimate that there are from 10 to 15 of them.

So what days can you get pregnant? The answer to this question is both simple and complex. Simple, because you can answer with confidence: on those days when a woman has, that is, when an egg ready for fertilization comes out of a mature and enlarged follicle on the ovary. Complicated, because it is not so easy to calculate this ovulation. Especially if the woman's menstrual cycle is not stable or the representative of the beautiful half of humanity is undergoing treatment for any diseases. However, there can be many reasons that affect ovulation.

Can you get pregnant during ovulation?

You can calculate it using a graph. IN high school, suffering over the construction of graphs of functions, many lament about the impracticality and remoteness from real life this kind of information. And at that time, it cannot even occur to anyone that in the future you can try to get pregnant using a schedule that will record information about body temperature in order to “hunt” for ovulation.

You can build it if for at least six months every morning (do not hack - this is required condition!) to measure body temperature in the rectum. The results should be recorded in a table or graph. During the approach of ovulation, body temperature rises by 0.5 degrees, and on the day of ovulation, as a rule, by 1 degree. As soon as the temperature has risen, you need to get down to business, because the chances of getting pregnant increase many times over. But here it is necessary to make a reservation that this method “works” for women who have an established constant menstrual cycle. Considering that during the period of ovulation in some months not one, but several eggs mature in the follicles, and this does not happen at the same time, but over 3-4 days, a woman can become pregnant not with the first, but with the second, or even third attempt. This means that as soon as the basal temperature begins to rise, you need to increase the number of sexual intercourses and continue them for another 2-3 days after the temperature drops.

In addition, you can get pregnant by calculating ovulation using special tests. These tests are similar to those used to determine pregnancy. Similarly, if the test is positive, two lines will appear on the test. You need to do tests to determine ovulation every day. And at the same time.

As a rule, ovulation occurs in the middle of the cycle. But it happens that it happens both at the beginning and at the end of the cycle. This is due to various failures. First of all, hormonal. However, these failures may be caused by stressful situations, any diseases, climate change and so on. This leads to the fact that surprises happen when you do not count on them at all.

You can get pregnant a few days before your period or a few days after it ends.

Yes, it's not a typo. And on such days you can get pregnant. The chances of successful conception in such cases are due to the individual characteristics of the woman's body. Also, this can happen if the menstrual cycle is severely disturbed. In the case of a very long menstrual cycle, ovulation may occur several times. The last of them, as a rule, just falls on the period before menstruation. This is especially true for those women who menstrual bleeding lasts about 7-10 days. Another category of women who more likely can become pregnant during this period, those who very rarely have sex. This happens because the human body, like the animal, is set up for procreation. If sexual intercourse is rare - the body "worries" that the performance main function becomes impossible and, in case of any sexual intercourse, reacts with unscheduled ovulation. The same applies to cases where a woman's sexual intercourse is regular, but always protected - using condoms or by preventing sperm from entering the genital tract through an interrupted act.

Can you get pregnant during your period

This is possible in cases spontaneous ovulation. The percentage of such conceptions is very low, since the secreted menstrual blood in most cases prevents the retention of a spermatozoon or an already fertilized egg in the uterine cavity. Moreover, the process of implantation of a fertilized egg into the endometrium is quite problematic, because during menstruation it exfoliates and comes out along with menstrual blood. But still, medicine is familiar with cases when conception occurred precisely during menstruation. This can happen if a woman's menstruation is long, and 2-5 days remain until ovulation itself. Under such conditions, a sperm cell that has entered the genital tract is likely to wait for an egg. Also, conception during menstruation is possible if a woman's menstrual cycle has gone astray due to illness, stress, and strong physical exertion.

Not always the presence of ovulation absolutely guarantees conception. This process is influenced different factors: the quality of the endometrium (the inner layer of the uterus into which the fertilized egg is implanted), the quality male sperm, general state women's health, periodic alcohol intake, wrong image life and more. Therefore, in order for those who wish to have a child to be lucky, you need to create the maximum favorable conditions.

Especially for Olga Rizak

The conception of a baby is possible only during the period when the mature egg leaves the ovary and is waiting for its fusion with the sperm. Women who want to get pregnant look forward to "that very day", while others, on the contrary, refrain from sexual intercourse at this time. But, if the day of the intended conception is incorrectly determined or missed, is pregnancy possible, and how long does the maximum fertility of the woman remain.

Fertilization - the process of fusion of a mature egg with a spermatozoon, as a result of which a zygote is formed, carrying the genetic information of both parents.

Accordingly, conception occurs when there is a mature woman in the body, which develops in the ovarian follicle from 10 to 18 days.

After this period, it leaves the cavity of the ruptured follicle, ready for fertilization. The process by which a mature egg is released is called ovulation.

For reference: the timing of the maturation of the follicle is individual and depends on the duration of the menstrual cycle. In 80% of women from 28 daily cycle the release of the egg occurs on the 14th day.

Main features

How many days after ovulation can you get pregnant?

Probability successful conception It is determined by two factors: the presence of fertile, viable sperm in a man and a mature egg in a woman.

Because spermatozoa retain their vital activity for up to a week, conception is possible with sexual intercourse that occurred 7 days before the release of the finished egg, and within 2 days after it.

most successful period for fertilization are the day of ovulation, the day before and after it. At this time, changes occur in the woman's body that are favorable for the passage of spermatozoa into: the consistency of the cervical mucus decreases, and the elasticity of the vaginal walls increases.

What cycle days are possible?

Life span of a mature egg lasts up to 24 hours, respectively, the process of fertilization takes place during the day. However, this does not mean that it should take place on this particular day.

sperm fertility can last up to 5 days, and, according to some researchers, up to a week. Therefore, sexual intercourse even a week before the expected ovulation may well end in conception.

Based on these data, a calendar method of contraception has been developed, through which it is possible to determine.

Important: the definition of fertile days is individual for each woman and depends on the duration of her menstrual cycle.

Rules for calculating fertile days:

Track the duration of three menstrual cycles.
From the number of days in the long cycle subtract the number 11.
From the number of days in the short cycle subtract the number 20.
The numbers that are in the range of the obtained values are the days on which conception is possible.

For example: the duration of the maximum menstrual cycle is 31 days, and the short one is 29. Thus, 29 - 20 \u003d 9; 31 - 11 \u003d 20. This means that from the 9th to the 20th day from the onset of menstruation, unprotected sexual intercourse may well end in pregnancy.

The probability of fertilization in a day

If terms probable conception before ovulation stretch for a week and are explained by the viability of spermatozoa, then after it, fertilization is possible up to 2 days, which is how long a mature egg can live in a successful scenario.

In addition, on the first day after ovulation, maximum fertility is determined.

IN female body at this time, favorable conditions are created for the penetration of spermatozoa into the egg, thanks to which the male germ cells reach their goal within 2 hours after entering the vagina.

A week later

Pregnancy a week after ovulation is impossible due to a number of physiological factors:

A mature egg cell lives no more than 2 days.
The maturation and release of the egg in the menstrual cycle occurs only once.
The process of fertilization is impossible without an egg.

Conception in a week after the alleged woman ovulation can only be explained by the failure of the menstrual cycle. That is, the release of the egg from the ovarian follicle occurred somewhat later.

Possible reasons for the violation of the timing of egg maturation:

Irregularity of the menstrual cycle.
Hormonal disbalance.
Medical therapy.
stress factors.

Doesn't always give accurate results. Allowed error up to three days, which also suggests that possible conception one week after the maturation of the egg.

How long is the chance?

Theoretically, fertilization can only occur with a viable female gamete , which persists for a day after leaving the follicle. But in fact, conception is quite likely even a few days after the supposed release of the egg.

This factor due to inaccuracy. All home methods, even in cumulative use, can give some error, on average, up to 3 days. The exact date egg release can be determined only by ultrasound.

How to conceive a child with maximum chances?

Exact determination of the date of maximum fertility important for women planning a pregnancy.

Sexual intercourse on an "auspicious day" significantly increases the chances of conception.

Fertilization is possible if intercourse occurs within 48 hours after the release of the egg.

Peculiarity: optimal frequency of sexual intercourse in fertile days should be every 2 days. With more frequent contacts, the viability of spermatozoa decreases.

Shouldn't despair I am in the absence of coitus on the day of ovulation. Conception is possible within 2 days. However, on day 3, the probability of fertilization is almost zero.

When to do the test?

The test determines the presence of pregnancy according to the concentration in the urine of a woman. The level of hCG begins to increase from the moment gestational sac into the uterus, which occurs on the 5th day after fertilization.

Around day 10 after conception, highly sensitive pregnancy tests begin to respond to increased hCG level in the body of a pregnant woman by the appearance of a second test strip.

Attention: it should be borne in mind that the probability of determining pregnancy by tests is 90%. The possibility of error cannot be ruled out.

On the 14th day after fertilization, even tests with medium sensitivity determine pregnancy.

How not to get pregnant?

If sexual intercourse is within 5 days, and the birth of a baby was not part of the woman’s plans at all, it is recommended to resort to measures emergency contraception. For this purpose, you should take medicines:

Levonorgestrel.
Postinor.
Escapelle.

Data drugs suppress fertilization and prevent zygote implantation. They should be taken no later than 3 days after unwanted sexual intercourse.

To prevent the onset unwanted pregnancy partner needs abstain from unprotected sexual intercourse c, using contraceptive methods, within 4 to 5 days after the expected ovulation.

Pregnancy with unprotected intercourse after ovulation is likely if coitus occurred within 2 days after the release of the egg. In order to avoid unwanted pregnancy on fertile days, it is recommended to use contraceptive methods.

For couples, who want to conceive a baby, "planning" should begin 5 days before the final maturation of the egg, maintaining a gap of 48 hours between sexual contacts, to preserve sperm fertility.

When can I get pregnant, more precisely - on what days of the cycle? This question worries both girls who want to quickly become mothers, and those who are not planning motherhood in the near future. When is conception most likely to occur?

Take, for example, a couple whose partners are not infertile. As you know, a woman can conceive a child only in the middle of the menstrual cycle, during a period called " ovulation", When an egg ready for fertilization is waiting for sperm. All women ovulate at different days, it depends on individual characteristics organism, the length of the menstrual cycle. And there are also "sterile" cycles, when the egg does not mature at all, the ovaries rest. And this does not mean that the woman is not healthy. Also, ovulation is absent during pregnancy, may not be during the entire period of breastfeeding, in those girls who do not yet have menstruation, when taking hormonal contraceptives, some medicines etc. And so, healthy woman with a menstrual cycle of about 28-30 days ( average duration) ovulation occurs on the 12th-16th day. With a shorter cycle - earlier, with a long cycle - later.

And how exactly to calculate the days when you can get pregnant? This can be done in several ways:

using an ovulation test;
measurement method basal body temperature;
according to subjective feelings;
according to the results of ultrasound examination.

Not all women have such sensitivity to be able to determine the days when it is impossible to get pregnant and when it is possible, not everyone has the time and money to go to ultrasound and buy special tests, therefore the most popular method is to measure basal temperature. By regularly measuring the temperature in the rectum and building graphs, you can quite high precision predict "dangerous" and "safe" days.

But are there cases when conception occurs outside of ovulation and how soon, more precisely, when can you get pregnant after menstruation? In fact, even sexual intercourse that took place at the beginning of menstruation can give new life. For this, only 2 conditions must be met: the period from one period to another must be short, and the spermatozoa must be viable. Thus, ovulation can occur, for example, on the 10th day, on this day conception will occur, although intimate relationship were 3-4 days before. After ovulation, the egg remains viable for no more than 2 days. So, if ovulation has definitely passed, then the period after it until the next menstruation (approximately 2 weeks) is the safest for those who are not yet eager to have children. This is such a peculiar method of contraception called "calendar". However, it does not differ in accuracy. And the question "when you can get pregnant before menstruation or after" is not correct.

What days you can not get pregnant - a lot depends on the answer to this question. Therefore, we would not recommend too much trust in the methods of calculating these days, which we will give below. But, of course, it's up to you to decide.

Surely you know that you can not conceive a child on any day, since you have already asked yourself the question of calculating “dangerous” days. Yes it is. During one menstrual cycle (which lasts an average of 28 days), the chance of getting pregnant is high for about 7 days in the middle of the cycle. And the rest are the days when you can not get pregnant. How to calculate "when it is possible, and when it is impossible?"

The most popular method is to measure the temperature in the rectum. All you need is a regular mercury or electronic thermometer(The first one will be more precise, therefore it is preferable). Next, you need to measure rectal temperature every day, at least the first half of the cycle, in the morning and do not forget to write down all the measurement results.

On days when you can not get pregnant, the temperature will be below 37 degrees. But this is not an axiom, there are exceptions. Until ovulation occurs rectal temperature is at the specified level. However, spermatozoa are very tenacious, and even being in the female genital tract, they can remain viable for several days. Therefore, sexual intercourse that occurred 5 days before ovulation may also turn out to be “effective”. Further, ovulation - it is expressed by raising the temperature values \u200b\u200bto 37 degrees and above. The egg remains viable for no more than 2 days, which means that the days when you cannot get pregnant come just after ovulation. That is why they say that the most safe days- these are the ones before the most monthly. However, there is a nuance here - elevated temperature may be not only due to the maturation of the egg, but also due to illness, taking certain medications, after intercourse, if the woman took less than 6 hours vertical position(for example, getting up at night to go to the toilet). Accordingly, ovulation did not occur on that fixed day, and the couple "relaxed" on the day when ovulation actually occurred. The result is pregnancy. It is quite difficult to use the basal temperature chart for those women who have an irregular menstrual cycle.

Another way to determine ovulation and without dangerous days, respectively, are tests. Very reliable, but it turns out to be too unprofitable, since you will have to test for several days in a row, and this is money. In general, for those who want to save on contraception using calendar method protection from unwanted pregnancy, this option is not at all suitable. Accordingly, ultrasound is an even more expensive method that also requires time.

Therefore, the only option left is to follow your feelings. In many expectant mothers, during the period of egg maturation, the lower abdomen is pulled, the pain can be stabbing or cramping, but not regular. Abundant mucous discharge from the vagina appears. Accordingly, having learned which days it is impossible to get pregnant, the calendar can make up and different colors display "dangerous" and "safe" days there. By the way, there are good handy programs that allow you to create a calendar. If your cycle is regular, then it makes sense to use them.

We draw conclusions.

1. The safest days are the beginning of menstruation, as well as the days before the very beginning of the next period.

2. It is impossible to get pregnant in the anovulatory cycle, when ovulation does not occur.

3. You can’t get pregnant in the first 2 weeks after giving birth (really, who would think of having sex these days?)

In this way, you can calculate on which days you can not get pregnant, and on which you can. As we wrote at the beginning of this article, none of the described methods is 100% correct. It is better to choose an effective contraceptive More than enough variety. Do you have rare sexual relations? Then oral contraceptives are unlikely to suit you. It would be wiser to use condoms or even spermicides - "chemical" contraception. With regular sexual intercourse and one healthy sexual partner, gynecologists recommend using intrauterine device, Vaginal Ring Ring or birth control pills. By the way, birth control pills, although not combined (containing only 1 hormone), can also be drunk by nursing mothers. In general, there is always a choice. Do not risk your health, better go for a consultation with a gynecologist.
