How correctly to calculate monthly? Monthly calendar, monthly cycle - comprehensive information for women

Why did nature create a woman? It would seem a strange question. Of course, a woman is needed in order to help a man in matters of the soul, support him, feed him, educate his children. But in fact the main purpose of a woman in nature is to bear and give birth to a child. This is the peculiarity of the woman's reproductive system. Each cell of her body acts so that she can reproduce the like.

Reproductive system of a woman

The reproductive system of a woman acts at the expense of the ovaries and the uterus. It is worthwhile to figure out what is happening in the ovaries, and how the uterus takes part in this process. The ovary ripens in the ovaries, which then leaves the abdominal cavity. In the uterus, under the influence of sex hormones, changes in the endometrium take place, so that a fetal egg can be fixed in it after conception.

It should be understood that oocytes, in contrast to male spermatozoa, are limited in number. Even in the womb of the girl, 400-450 ova mature, which will exist until the end of the reproductive age. By the way, about him. The woman's reproductive age starts from 15-18 years and ends about 40-50 years, each woman has different ways. Then comes menopause, when hormones are produced to a lesser extent.

Menstrual cycle and menstruation - these are terms that you need to know in order to be able to calculate the monthly, understand how the conception takes place, and so on.

Menstruation and menstrual cycle: what's the difference?

So, the first term with which you need to understand is the menstrual cycle. This is a rather complex process in a woman who is characterized by cyclic changes in the sexual, endocrine, nervous system.

Menstruation - is the allocation of blood from the genital tract, caused by the rejection of the unfertilized ovum and the mucous membrane of the uterus. Usually the first menses for a girl starts at 10-12 years.

So, now it is clear that these two words mean different processes, and not vice versa, as many think. In more simple terms, the menstrual cycle is the time from the onset of one menstruation to the beginning of the discharge in the next month. But I must say that the cycle includes several stages, knowing which, it is easy to understand how to calculate monthly.

1 phase is the time interval from the first day of the appearance of blood to the moment of ovulation, that is, the release of the egg into the body cavity. This action occurs under the influence of the female hormone estrogen. The phase is called follicular.

The second phase is luteal, the stage from the exit of the egg to the next menstruation. To the action of the main hormone joins the hormone of pregnant women - progesterone.

Thus, if conception occurred during the period of ovulation , then the action of the main hormone slows down and is replaced by the second. And if there was no conception, then the upper layer of the endometrium, together with the ovum, is rejected, and the menstrual period begins.

Length of the menstrual cycle. Norm. Pathology

Now it is necessary to understand what the normal length of the menstrual cycle is, why it is just such, and what are the deviations from the norm.

So, the normal menstrual cycle lasts about 28 days for most women and girls, but it also happens that the interval between menstruations reaches 35 days or 21. These figures are again explained by female physiology. The first phase of the cycle is aimed at ensuring that the egg is ripe, and ovulation has occurred, the second phase is to change the endometrium, if conception has occurred. If the fertilization of the egg does not take place, the functional layer of the endometrium disappears, and after a while the menstrual period begins.

Why do not the monthly come on time?

If the monthly does not come on day 36-39, and the possibility of pregnancy is excluded, it is worthwhile to think about the health of a woman. The absence of menstruation can be caused by many diseases of the female reproductive system, hormonal changes. Delay can cause oral contraceptives, also common in our time, stress or cold, polycystic ovary. If after 7-8 days your cycle does not return to normal, you need to visit a doctor to find out the reasons why there are no menstruation.

In order for the discharge to be regular and to be able to conceive a child, a woman needs to take vitamins, especially those containing lutein, eat right, less nervous at work. After all, you will agree, health is more important, especially if there is a desire to become the mother of a beautiful and healthy baby.

How do I know when the next month will come?

After reading the above, the question may arise: "And how to calculate the period of menstruation?" In fact, nothing complicated in this. You will need attention, a good memory, a sheet of paper or a calendar, a red pen and a desire to know when to wait next time for menstruation. In order to make a monthly schedule, calculate their duration, you need to know the date when the allocation began, and the day when they ended. It is best to mark them in the calendar or to write in a notebook. In her notebook, the girl should note the duration of her periods, her feelings at the same time, forgetting nothing, otherwise the calculation will be incorrect.

For the busiest there are special programs on the phone that can be closed with a password and used every month. In this case, they will remind of the next menstruation with a special signal or a pop-up window.

How to make a monthly calendar?

It has already been said that in order to calculate the monthly, you will need a calendar. It is better if it is large. Then it is more convenient to note the intensity of blood secretions. According to gynecologists, this will help you determine the painfulness of menstruation, because if it is accompanied by severe pain, it is advisable to check your health.

So, the girl comes the first day of the month, highlighting and not causing inconveniences. She must take her calendar, which is designed specifically for this, and circle this day with a red handle, and sign from below with the intensity of the blood and whether there is pain. If you use a small calendar, you need to shorten the word to one letter, that is, if the monthly smearing and painless, then you can write: "B and M". This is noted every day until the last and a characteristic is given to everyone. Allocations can be abundant, minor, medium and, as already mentioned, smearing.

The last day of menstruation passed. Now it is possible to live a month quietly. Menstruation next month, the girl continues to celebrate every day, until the last.

When there was information for two months, you can find out which day will be ovulation. To do this, you need to subtract 14 from the last day of the cycle. Approximately at this time, the egg will come out of the ovary, and it is possible that conception will occur.

Why do I need to know the date of the next menstruation?

Now, when it is known how to calculate the next monthly, the question arises - why? What is the date of menstruation? There are several reasons for this, from very comical to serious ones.

So, if a female representative can calculate monthly, she will not have to run to the store on the day of the beginning of the discharge and buy gaskets to ensure personal hygiene. She will have several things in her purse for this period. Another comical reason is that a young man or husband will know when to agree with his beloved in everything and smile, even if he does not like something, or quietly go to the TV, so as not to irritate her. Then there are more serious reasons: a longer menstrual cycle can talk about dysfunction of the ovaries, which delays ovulation. Also, the delay or too short a period between menstruation may indicate serious illness and the inability to become pregnant.

The calendar method as a means of unwanted pregnancy

Above we talked about how to calculate monthly in order to increase the chances of having a child. But in life there are situations when the girl is still too young to have children, so she uses the calendar method to protect her from pregnancy. This method is quite simple. During ovulation and 3 days after it, sexual intercourse is excluded. But, as already mentioned, the menstrual cycle has the ability to shift under the influence of various factors, so this method will not give a 100% guarantee of the result.

But if the girl prefers this method, the monthly calculator will help her. Calculate with it, you can and ovulation, and the days when sex will be safe.
