Pregnancy is a long-awaited and happy time for most women. Having come to a common decision to have a child, many couples expect that conception will occur very soon. However, sometimes you have to wait several months, and often much longer. If both potential parents are he althy, then pregnancy most often does not occur due to improper planning of the time of conception. It is possible strictly at a certain moment. Is it possible to get pregnant after menstruation? Or conception occurs before their onset? To answer these questions, you need to figure out how a new life begins to appear in a woman's body.

Ovum Development

When can I get pregnant after my period? On the first day, if by this time the egg has already matured. Even during their intrauterine life, each female fetus begins to form ovaries, containing several thousand eggs. They are located in small formations- follicles. The eggs during this period are immature. The girl is born, grows and reaches puberty. From this moment, the regular maturation of eggs begins, which, after fertilization by spermatozoa, will give rise to a new life. This process is regulated by the pituitary gland by increasing the concentration of certain hormones in the woman's blood at the time of egg maturation.

The follicle, located on the surface of the ovary, begins to grow, acquires signs of a cystic formation up to 20 mm in size. Inside it, the ovum matures under the action of hormones. At the same time, the growth of the follicle causes an increase in the concentration of the hormone estrogen in the blood of the expectant mother. Under its action, the growth of other ovarian follicles stops. The maturation of the egg is accompanied by a change in the endometrium - the inner layer of the uterus. During the previous menstruation, it almost completely disappeared, and a favorable environment is needed for the development of the fetus from a fertilized egg. Therefore, the endometrium is renewed.

Ovulation

How many days can I get pregnant after my period? It depends on when you ovulate. This is the process of disintegration of the follicle and the release of the egg that has matured in it. Ovulation is the defining moment in the process of pregnancy. The egg travels through the fallopian tube towards the uterus. If during this period she meets with a viable sperm, then her fertilization occurs. At the same time, at the site of the follicle that burst during the exiteggs, a corpus luteum appears. If conception occurs, it will produce the hormone progesterone, which ensures the normal course of pregnancy. Ovulation occurs most often 14 days before the onset of menstruation. If a woman's cycle is stable and has 28 days, the egg matures in its middle. This allows you to determine exactly the period when the conception of a child is most likely. If the menstrual cycle is less than or exceeds 28 days, then the duration of its first phase changes. The next phase (the time after the release of the egg and before the onset of menstruation) is also about 14 days (12-16).

Ovulation symptoms

Some women at the time of ovulation feel pulling or cutting pains on the side where the ovary is located, on the surface of which the egg has matured. It is believed that this is due to damage to the mucous membrane of its surface. Such pains are usually short-term, only in a small number of women they last more than a day and cause significant inconvenience. If this situation persists during the next cycle, it is better to consult a doctor. He will determine the cause of the ailment and prescribe appropriate treatment if necessary.

Methods for determining the moment of ovulation

What is the probability of getting pregnant after menstruation? Finding out this will help determine the time of ovulation. Since this procedure is the first step towards a long-awaited conception, several special methods can be used. They make it possible to accurately determinewhen the egg will be released. There are two most popular ways.

1. Basal body temperature

Determination of basal temperature - its measurement in the rectal area. It is better to produce it with a conventional mercury thermometer, since an electronic device can give significant errors. The measurement is taken in the morning, at the same time every day. It is best to do it immediately after sleep, while in bed.

In the first half of the menstrual cycle, the same temperature is observed every day - about 37 degrees. Then, a day before the onset of ovulation, it decreases slightly, then there is a jump of 0.5 degrees. This means that the egg has been released. If the thermometer readings do not change throughout the cycle, most likely, ovulation did not occur.

It is worth remembering that such a method cannot be completely reliable. The basal temperature can be affected by the woman's drinking, smoking immediately before the measurement, or sexual intercourse shortly before the procedure. Stress or an infectious disease also distorts performance.

To most accurately predict the onset of ovulation and find out how to quickly get pregnant after menstruation, it is worth measuring the temperature in the rectum for 3 months. In doing so, you need to make a schedule. If there are any factors affecting the measurement result, such as a cold, these should also be noted. Based on the results of all measurements, it will be possible to predict on which day of the next cycle ovulation will occur.

2. Determining the day of ovulation usingspecially designed tests

Using this method, it is easy to find out how many days you can get pregnant after your period. These tests can be easily purchased not only at the pharmacy, but also in many stores selling a variety of goods. The action of these tests is based on determining the concentration in the urine of a hormone that synthesizes the corpus luteum. If, after the measurement, the test showed one band, then there is still a lot of time left before ovulation occurs. If there are two stripes, then ovulation is already close. The moment of its onset is determined by the color intensity of the second band that appears. As soon as its color matches the shade of the control, the moment of release of the egg has come. This method is quite accurate, however, you need to purchase more than one test. Measurements are recommended to start taking 6 days before the expected date of ovulation. So the girl is able to find out when you can get pregnant after menstruation.

The structure of spermatozoa

Spermatozoa, unlike eggs, are constantly updated in the body of a man. They are formed in the testicles constantly, not cyclically. As a result of the process of ejaculation, millions of sperm enter the external environment.

Sperm is a single-celled organism that carries a certain set of genes. Three components are distinguished in its structure.

1. Head. It contains genetic material - 23 chromosomes. The head also contains a special component that can dissolve the wall of the egg in order to penetrate insidecells.
2. Neck. This is the link between the head of the spermatozoon and its tail.
3. Ponytail. This part of the sperm plays an important role - it ensures its mobility. The tail contains mitochondria, which release energy and allow the sperm to move.

Sperm Viability

The viability of spermatozoa and, accordingly, their ability to fertilize an egg are determined by the coordinated functioning of the male reproductive organs of the secretory function. Sperm must have a certain composition of organic substances that are dissolved in it, the necessary acidity and viscosity. If all indicators are normal, then the spermatozoa are able to move quickly, remain in the fallopian tube for the required amount of time, and after fertilization lead to the appearance of a he althy fetus.

Fertilization process

Spermatozoa, once in the vagina, begin their upward trajectory into the fallopian tubes. It is there that they can meet with the egg moving towards them. There is an opinion that the sperm that first approaches it fertilizes it. Most often this is not the case. Spermatozoa are viable for 24-72 hours after the fact of ejaculation. To fertilize an egg, you need not only to get to it (it takes a long time), but also to penetrate into its inner layer. This happens by splitting the wall of the egg with a special substance located in the head. So more likely to fertilizethe egg has those spermatozoa that get to it at the moment of splitting the last layer of the wall.

After a sperm enters an egg, their genetic material combines, then its cells begin to rapidly divide. A zygote is formed. Cell division occurs when a fertilized egg travels through the fallopian tube to the uterine cavity. There, the zygote is introduced into the endometrium, which, in the process of egg maturation, acquires a structure favorable for the development of the embryo. The hormonal changes that accompany this whole process prevent the next period from occurring.

Factors affecting the occurrence of conception

Various factors can influence the possible fertilization of an egg. Under their influence, conception can occur at the most unpredictable moment, when, according to all calculations, it should not occur. And, on the contrary, even the most accurate calculation of the time of ovulation may not give a positive result and not lead to the onset of a long-awaited pregnancy. When planning the conception of a child, it is necessary to take into account the following features.

1. The normal lifespan of a spermatozoon is one to three days. However, sometimes it happens that they can last for a week. In medical practice, even cases of egg fertilization have been recorded a couple of weeks after the fact of sexual contact. You can also get pregnant right after your period. Of course, this is a rarity, but when planning a pregnancy, it is worth remembering the characteristics of the human body.
2. In the same menstrual cycle, in rare cases, two eggs can mature. They exit the ovary at different times. A woman can calculate the ovulation of one egg by calculation, but not assume that the second is already maturing. So there is a high probability of getting pregnant after menstruation.
3. The menstrual cycle, even in he althy young women, in whom it has been established for a long time and every month is clearly on schedule, can in some cases shift. The reason for this can be stress, significant physical exertion, past illnesses. In older women, disruptions in the ovulation schedule can occur due to hormonal changes in the body. For example, after the end of menstruation, you can get pregnant quite often, although at this time the woman does not expect ovulation.

Pregnancy and periods

It is believed that pregnancy cannot occur before, during or immediately after menstruation. Most often this is true. However, the characteristics of the female body, external factors, as well as the viability of sperm can make conception possible even during this period. So how many days can you get pregnant after your period?

Pregnancy is less likely to occur in the first days after the onset of menstruation. At this time, a particularly unfavorable environment for the life of spermatozoa is created. Even if, due to a shift in the cycle, an untimely ovulation occurred, they are unlikely to be able to fertilize the egg and die quickly.

The time before the onset of menses, at their completion, and immediately afterendings cannot be considered completely impossible for conception. A failure in the ovulation schedule, the release of two eggs at once during the cycle, as well as spermatozoa that persist for a long time, can lead to fertilization. As you can see, you can get pregnant right after your period. You have to be ready for anything.

Planning pregnancy by calculating the timing of ovulation

How many days can I get pregnant after my period? Calculating the time of ovulation can be very helpful for those women who want to get pregnant as soon as possible. Determining the moment of release of the egg not only makes fertilization possible, but also allows the expectant mother to assume the onset of pregnancy. A woman is more attentive to her he alth, trying not to allow any actions that could harm the he alth of the unborn baby.

Can a girl get pregnant after her period? Let's try to figure it out. If a woman is he althy, has regular periods and is not under stress, it can be assumed that she will ovulate on the 14th day for a 28-day cycle, and on the 16th for a 30-day cycle. Since sperm can last for about three days and an egg for up to 48 hours, sexual contact is most likely to lead to conception about three days before and after ovulation. This time starts from the 11th day of the cycle and reaches the 16th day. So, you can get pregnant a week after your period.

When choosing a method of contraception, you should not rely entirely on the calendar method based ondetermining the time of ovulation. After all, it is possible to become pregnant after menstruation, before they begin, and even at the end of menstruation. It is better to consult a gynecologist who will select more reliable contraceptives.
