The term "menstrual cycle" in medicine indicates successively and cyclically occurring changes in the organs of the sexual system of a woman. In each cycle there is a period when there is a rejection of the endometrium of the uterus, which is accompanied by a manifestation of bloody discharge, this is menstruation.
The first day in the menstrual cycle is considered the day of the onset of bloody discharge. The total cycle time is approximately 28 days, but it can vary. In different women, the menstrual cycle can be either shorter or longer. Therefore, there is often a question how to calculate your menstrual cycle?
Conditionally the menstrual cycle is divided into "safe" and "dangerous" days. Dangerous are those days when a woman can become pregnant, and safe - when pregnancy can not come. The probability of pregnancy is especially high during the period of ovulation. This process is associated with the release of the ovule from the follicle, when it is fully ripe and ready for fertilization. Therefore it is important to be able to calculate your menstrual cycle. Thanks to this, you can protect yourself from unwanted pregnancy and have sex safely. On the other hand, this will help prepare for conception in planning pregnancy and childbirth.
It should be noted that it is not always easy to calculate the cycle days, since the menstrual cycle can be unstable.
It should be noted that dangerous and safe cycle days for women are useful only in order to prevent unwanted pregnancies. However, this is not a method of contraception and there is still a threat of getting an infectious disease transmitted sexually. In case a woman has only one sexual partner, then it is possible to reduce contraception solely to control over the stages of the menstrual cycle. If the cycle is lost, some changes are evident in the body, it is necessary to urgently appeal to the gynecologist.
So, how to correctly calculate the menstrual cycle. To this end, there are various methods used equally successfully. Modern women are given the opportunity to use special programs for calculating the cycle, posted on the Internet. They are easy to find information on how to correctly determine the beginning of ovulation, how to calculate the date of delivery when bearing a child, how to determine the sex of the fetus and learn about the onset of premenstrual syndrome. Doctors-gynecologists recognize the convenience of such specialized programs, so the results of calculations can be printed and taken to take with them.
Self-calculation of the menstrual cycle is performed manually. However, in order to correctly calculate your cycle, you need to monitor your body and health for about six months. During this period, you must choose the shortest and longest cycle. Count the number of days in the cycle from the first day, when one menstruation began and until the first day of the next discharge. Then, from the number that compiled the days of the longest and shortest cycles, you should subtract 18 and 10 days, respectively. The first digit indicates the number of safe days from the beginning of the month, the second also indicates safe days, but at the end of the month. And the period between these numbers is considered very favorable for conception, since during this period the probability of pregnancy is highest.
Another method of calculating the menstrual cycle is to regularly measure basal temperature, on the basis of which a graph is built. This method is considered the most effective, and doctors recognize it as the most accurate of all existing today. To measure body temperature follows within a month. In the first days of the menstrual cycle, it is at a level of 37 ° C. Then, after about a day, the temperature drops to 36.6 ° C. After one more day it rises again, reaching 37.5 ° C, and remains on this level until the end of the menstrual cycle, slightly falling just before the beginning of bloody discharge. In case of pregnancy, the temperature will remain at the same high value as in the middle of the cycle. If the thermometer readings were not raised at all, this means that any day of the cycle can be considered safe, conception will not occur.
