Why did nature create woman? It would seem a strange question. Of course, a woman is needed in order to help a man in spiritual affairs, to support him, to feed him, to raise children. But in fact, the main purpose of a woman in nature is to bear and give birth to a child. This is a feature of the reproductive system of women. Each cell of her body acts in such a way that she can reproduce her own kind in the light.
The reproductive system of women
The reproductive system of a woman acts through the ovaries and uterus. It is worthwhile to understand what happens in the ovaries, and what part the uterus takes in this process. In the ovaries, the egg matures, which then enters the abdominal cavity. In the uterus, under the influence of sex hormones, changes in the endometrium occur, so that the fetal egg can be fixed in it after conception.
It must be understood that, in contrast to the male sperm, the number of eggs is limited. Even in the womb, 400-450 eggs that mature until the end of reproductive age mature in the girl. Speaking of him. The reproductive age of a woman starts from 15-18 years old and ends around 40-50 years old, each woman has a different way. Then comes menopause, when hormones are produced to a lesser extent.
The menstrual cycle and menstruation are terms that you need to know in order to be able to calculate your period, to understand how conception occurs and so on.
Menstruation and the menstrual cycle: what is the difference?
So, the first term to deal with is the menstrual cycle. This is a rather complicated process in a woman, which is characterized by cyclical changes in the reproductive, endocrine, and nervous systems.
Menstruation is the discharge of blood from the genital tract caused by rejection of an unfertilized egg and uterine mucosa. Usually the first menstruation in a girl begins at 10-12 years.
So, now it’s clear that these two words mean different processes, and not vice versa, as many people think. In simpler terms, the menstrual cycle is the time from the beginning of one menstruation to the beginning of discharge in the next month. But I must say that the cycle includes several stages, knowing which, it is easy to understand how to correctly calculate your period.
Phase 1 is the period of time from the first day of the appearance of blood until 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.
2 phase - luteal, the stage from the release of the egg to the next menstruation. The action of the main hormone is combined with the hormone of pregnant women - progesterone.
Thus, if conception occurred during ovulation , 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, along with the egg, is rejected, and menstruation occurs.
The length of the menstrual cycle. Norm. Pathology
Now you need to understand what is the normal length of the menstrual cycle, why it is just like that, 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 menstruation reaches 35 days or 21. These figures are again explained by female physiology. The first phase of the cycle is aimed at making the egg mature and ovulation occurs, the second phase - at changing the endometrium if conception occurs. If the fertilization of the egg does not take place, the functional layer of the endometrium departs, and after a while menstruation occurs.
Why periods do not come on time?
If menstruation does not come on day 36-39, and the possibility of pregnancy is excluded, it is worth considering the health of the woman. The absence of menstruation can be caused by many diseases of the female reproductive system, hormonal changes. Oral contraceptives can cause a delay, as is now common stress or a 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 periods.
In order for the discharge to be regular and to have the opportunity to conceive a child, a woman needs to take vitamins, especially those containing lutein, eat right, and be less nervous at work. You see, health is more important, especially if there is a desire to become the mother of a beautiful and healthy baby.
How to find out when the next menstruation comes?
After reading the above, the question may arise: "How to calculate the period of menstruation?" In fact, there is nothing complicated about this. You will need attentiveness, a good memory, a piece of paper or a calendar, a red pen and a desire to know when to wait for your period next time. In order to make a schedule of menstruation, to calculate their duration, you need to know the date when the discharge began, and the day when it ended. It is best to mark them on a calendar or write in a notebook. In her notebook, the girl should note the duration of her period, her feelings while not forgetting anything, otherwise the calculation will be incorrect.
For the busiest, there are special programs on the phone that you can close with a password and use every month. At the same time, they will remind you of the next menstruation with a special signal or a pop-up window.
How to make a menstrual calendar?
It has already been said that in order to calculate your period, you will need a calendar. Better if it will be large. Then it is more convenient to note the intensity of blood secretions. According to gynecologists, this will help you determine the pain of menstruation, because if it is accompanied by severe pain, it will be advisable to check your health.
So, the girl comes the first day of menstruation, the discharge is smearing and does not cause inconvenience. She should take her calendar, which is designed specifically for this, and circle this day with a circle of red pen, and sign below, with what intensity the blood goes and whether there is pain. If you use a small calendar, you need to reduce the word to one letter, that is, if the monthly smear and painless, then you can write it like this: "B and M". So it is celebrated every day until the last and a characteristic is given to everyone. Allocations can be plentiful, insignificant, medium and, as already mentioned, smearing.
The last day of menstruation has passed. Now you can live peacefully for a month. The girl continues to celebrate menstruation next month every day, right up to the last.
When information appeared for two months, you can identify on what day ovulation will be. To do this, subtract 14 from the last day of the cycle. At about this time, the egg will exit the ovary, and it is possible that conception will occur.
Why do I need to know the date of the next menstruation?
Now that we know how to calculate the next period, the question arises - why? Why do I need to know the date of menstruation? There are several reasons, from very comical to quite serious.
So, if a female representative can calculate her period, she will not have to run to the store on the day the discharge starts and buy pads to ensure personal hygiene. She will already have several necessary things in her purse for this period. Another comical reason is that a young man or husband will know when you need to agree on everything with his lover and smile, even if he does not like something, or quietly go to the TV so as not to annoy her. The more serious reasons follow: a longer menstrual cycle may indicate ovarian dysfunction, which delays ovulation. Also, a delay or a too short interval between menstruation can indicate serious illness and the inability to become pregnant.
The calendar method as a remedy for unwanted pregnancy
It was said above about how to calculate your period in order to increase the chances of having a baby. But in life there are situations when a 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 tends to shift under the influence of various factors, so this method will not give a 100% guarantee of the result.
But if a girl prefers this particular method, her period calculator will help her. It can be used to calculate ovulation and the days when sex will be safe.
