One of the most frequently asked questions - how to calculate the menstrual cycle. There are several important reasons for which once a month you need to produce elementary calculations. So why do you need it?
- For insurance. Each girl with annoyance will noted that critical days have a property to take off surprise and, accordingly, put in an awkward situation. Having thoroughly examining the cycle of its menstruation, you can keep the situation under control.
- To raise the chances of pregnancy. By simple arithmetic calculations determine the term ovulation. Then, in the most suitable days for conception, the days are made more intense, so that the pregnancy test is probably shown a positive result!
- To avoid pregnancy. In potentially dangerous for conception days of sex, it is better to avoid or use barrier contraceptives - this is quite accurate natural Contraception method. But 100% trust this method is still not worth it, because the complex processes of physiology are not subject to the calculation completely, and the ovulation of many women happens more often once a month.
- For female health. If you determine the period of the monthly cycle for several months in a row, you can monitor its stability and by how long it continues. With any suspicious changes, you need to contact the gynecologist for timely detection of the problem.
Menstrual cycle and critical days
Distinguish 4 phases:
- Follicular phase.
- Phase ovulation.
- Lutein phase.
- Deskvamation phase (critical days).
The front pituitary proportion in the brain produces a follicle-stimulating hormone, under the influence of which progesterone and estrogens are produced in the ovaries (their number prevails). The latter stimulate the formation and ripening of follicles, among which the dominant follicle will be determined later. Closer to the completion of the follicular phase (approximately in the middle of the monthly cycle) an ovulation occurs.
The duration of this period is 3 days. The pituitary glands produces a luteinizing hormone, which, falling into the blood, stimulates the production of progesterone. Under the influence of estrogen and progesterone, the dominant follicle bursts, releasing the ripe eggs through the uterine tubes in a small pelvis. This is ovulation.
During Lutein phase The female organism produces a lot of progesterone: the substance appears as a result of a luteinizing hormone hormone, and is also produced by a yellow body, which is formed on the site of a burst follicle. In the lutein phase, the mucous membrane of the uterus thickens, becomes more loose and viscous. Such changes are necessary for fixing the fertilized egg. If fertilization has not happened, after 12 to 16 days menstruation will begin.
Menstruation - nothing but other than rejection of the neop-procreated egg and finished to its implantation of the endometrium layer. This process indicates a failed pregnancy. Some time before menstruation in the body, women are not quite pleasant to her changes. So, on the eve of critical days, frequent mood swings, irritability, body temperature and blood pressure, painful breast swelling. These symptoms gradually decrease and disappear on the first day of menstruation.
It's important to know
Our site focuses on its readers on the following important information:
- every woman is unique, and all calculations should not be done «On the eye», strictly in accordance with your own data;
- Successfully use calculations to determine the days favorable or dangerous for conception, you can only only if the menstrual cycle you have stable! Permissible deviation from the norm consider difference in 1 to 3 days;
- We remind you that the menstrual cycle is a period of the first day of monthly to the first day of the following monthly. The first day of menstruation occurs when the selection becomes saturated red. Dynamot uncertain color of allocation for the beginning of menstruation do not accept.
How to count the cycle of menstruation to conceive
So, bearing in mind that in the first day of the cycle we accept the first day of menstruation, and for the last - the last day before the next menu, we make simple calculations.
The most fruitful in terms of conception period is considered to be the ovulation phase, which comes into force on the 14th - 16th day after the start of menstruation. Outside the ovary, the ripe egg is active and is capable of fertilization one day. However, it is possible to conceive a child, even a few days before the arrival of ovulation, because the viability of spermatozoa outside the sperm is saved from 2 to 5 days.
To correctly calculate the cycle of menstruation, carefully examine your cycle over the past year (or at least half a year). Determine the longest and shortest cycles. From the value of the shortest one you need to take away 18, from the value of the longest - 11. For example, your longest monthly cycle amounted to 33 days, and short - 26. We believe: 33 - 11 = 22; 26 - 18 = 8. The gap between 8 and 22 during the day of the cycle is the most appropriate time for the likely conception.
How to count the cycle of menstruation to not get pregnant
It is also necessary to study the features of the menstrual cycle, if you are interested in the question of how to prevent conception. Safe count the time that comes a day after ovulation: the egg has already died, and fertilization will not happen. But it is worth remembering that the exact date for the start of ovulation by ordinary calculation is very difficult to determine, and you can even become pregnant, even a week before ovulation. It is better to choose other contraceptive methods with a higher degree of efficiency.
You need to count the menstrual cycle not only when you want to get pregnant or prevent conception. In stability and regularity of the monthly cycle can be judged on the state of the health of the woman. For example, significant menstruation delays and very painful monthly signal signals Endometriosis, inflammatory processes in the uterus or in the ovaries. This means that to have a clear idea of the peculiarities of your body would not hurt every woman.
