How to Calculate Menstrual Cycle

The medical term "menstrual cycle" means certain changes in the female body that occur cyclically in the organs of the reproductive system. During the cycle, a period occurs when every woman has menstruation - rejection of the endometrium (the functional layer of the uterus), which manifests itself in the form of bloody discharge. The first day of the menstrual cycle is the day of the onset of menstruation, and the whole cycle lasts an average of 28 days, although for different women this period may be more or less.

The conditionally female cycle is divided into "dangerous" and "safe" days - as the name implies, the first woman has the opportunity to become pregnant, the second such danger is absent. The probability of pregnancy in the period of ovulation is high, when the egg leaves the follicle completely ready for fertilization. In this regard, it is very important to know how to calculate the menstrual cycle - it is necessary not only to safely have sex without risking conceiving a child, but also to prepare for this conception if pregnancy is the main goal of a woman. However, it should be remembered that calculating the days of the cycle is quite difficult, because not all women have it stable.

At once it is necessary to tell, that the woman can learn the "dangerous" and "safe" days only to warn against unwanted pregnancy. For all other cases, this method of contraception is not desirable - in sex without protection there is a danger of suffering from sexually transmitted diseases. If a woman has only one sexual partner, then it is possible to limit contraception and control over her cycle. If the menstrual cycle is lost - in the body there are any changes that clearly symbolize the need to consult a doctor.

How and how to calculate the menstrual cycle most successfully? There are several ways for this, and each of them can be used equally equally. Modern women more and more often prefer to use computer technologies, especially since there are a lot of corresponding programs that contribute to this. Such technical developments help not only to correctly determine the time of onset of ovulation, but also to calculate the time of delivery in case of pregnancy, determine the sex of the unborn child and track the time of onset of premenstrual syndrome. Even gynecologists note the convenience of such modern tools - the results can be quickly printed and brought with them to the reception.

You can do the calculations yourself and manually. Before calculating the menstrual cycle, you will have to monitor your health for six months to choose the shortest and longest cycle. The number of days should be counted from the first day of the onset of one menstruation and until the first day of the next. After that, the number of days of the longest and shortest menstrual cycles will need to subtract 18 and 10 days, respectively. The first digit will mean the number of "safe" days at the beginning of the month, the second - the same at the end. The period between them can be considered favorable for conception - at this time the most likely occurrence of pregnancy.

Another way that can be considered one of the most effective for those who want to know how to calculate the menstrual cycle is to regularly measure basal temperature. This method - the method of scheduling - doctors is considered the most accurate. If you measure the temperature during the whole month, you can see that in the first days of the cycle it keeps at 37 ° C, drops to 36.6 ° C in a day, and then rises again to 37.5 ° C a day later. At the same level, the temperature keeps to the very end of the menstrual cycle, slightly lowering before the onset of menstruation. In case of pregnancy, the thermometer will show the same high value as in the middle of the cycle, and if the temperature does not rise at all, then any day can be considered "safe".
