Useful information: how to count the menstrual cycle

So arranged by nature that a woman, except her beauty, charm, charm and other virtues, has a huge advantage over the strong half of humanity. It is the woman who was created to give life, that is, to continue the human race. This gift requires a kind of payment from the female body (monthly, pregnancy, childbirth, etc.). Since in a dispute with the creator we still do not win, the women "adapted" and mastered the rules of their existence.

There are a lot of important things about women's health, which must know the representative of the beautiful half of humanity. One such question is how to count the menstrual cycle.

Why is it so important? As already mentioned, the main function of a woman is to conceive, bear and give birth to a child. It is to these processes that her organism is prepared, the knowledge of the features of these processes greatly facilitates life.

What is the menstrual cycle? These are the physiological changes that occur in the female body (not only in the reproductive system) in the process of preparing for pregnancy. The main role in this process is played by hormones that are produced in the brain and ovaries. Menstruation is an external manifestation of the cycle.

Knowing what the length of the menstrual cycle is, you can calculate at what period the probability of conception is highest, and in what - is unlikely. This information is useful not only in planning pregnancy, but also in the opposite case. However, knowledge of the menstrual cycle and sex in "safe" days is by no means the most successful method of contraception.

How to count the menstrual cycle

The organism of each woman is unique, therefore all calculations must be carried out individually. The course of the cycle depends on the woman's health, hormonal background, physical activity and stress.

The following measurement is generally accepted: the first day of menstruation is the first day of the cycle, the last day before the next menstruation is the last day of the cycle. Normally, it is 28 ± 7 days. It is important that the cycle is stable, variations of 1-2 days are allowed.

Conditionally the whole cycle can be divided into two phases: follicular and luteal. They differ in controlling the process of hormone. There is another phase of menstruation and the phase of ovulation, although this division is not entirely correct from the position of the hormonal background, but they most accurately reflect the processes that occur in the ovaries and uterus.

The first phase begins on the first day of the month. The controlling factor is follicle - stimulating hormone (FSH). During this period, active estrogens promote maturation in the ovary of the egg.

In the middle of the menstrual cycle, the mature follicle leaves the follicle, moving to the fallopian tube (ovulation).

The second phase begins during the period of ovulation. The controlling factor is luteinizing hormone (LH). At the site of the bursted follicle, a yellow body forms, which produces progesterone. Under its influence, proliferation of the endometrium occurs; If fertilization has occurred, then the egg is attached to the uterus, otherwise after 12-16 days menstruation begins.

How to calculate a menstrual cycle in order to become pregnant

The most suitable period for conception is the phase of ovulation, which occurs 14-16 days after the onset of menstruation. After leaving the ovary, the egg "lives" and retains the ability to fertilize 24 hours (plus or minus 24 hours). But you can get pregnant a few days before the onset of ovulation, since the sperm is viable outside the seminal fluid for 2 to 6 days.

We apply in practice. How to count the cycle of monthly

The first case is the analysis of the cycle time for the year (minimum for six months). It is necessary to find the longest and shortest cycle. From the shortest we subtract 18, from the longest 11. For example, the longest cycle is 32 days, the shortest is 27. We calculate: 32-11 = 23; 27-18 = 9. The period between the 9th day of the cycle and 23 is the time of probable conception.

If your priority is the issue of protection from pregnancy, then the question of how to count the menstrual cycle is no less important. Safe days of the cycle start one day after ovulation. By this period, the ovum has died, so the process of fertilization is impossible. The only nuance: to calculate the date of ovulation with 100% confidence is quite difficult, in addition, you can get pregnant even 7 days before ovulation. Therefore, it is more effective to use other means of protection.

The question of how to count the menstrual cycle is important not only in relation to girls who want to become pregnant (or their opponents). By regularity, intensity and stability of the cycle, one can judge the health of the sexual sphere of a woman. So, severe pain with menstruation can signal about endometriosis, inflammation of the uterus, appendages, etc.

Proceeding from the foregoing, the study of the menstrual cycle is not a whim, but important knowledge about one's health, which every woman, girl, girl should own .
