When a girl begins sexually, she wonders how to calculate safe days to avoid an unwanted pregnancy. Every woman knows that the conception of a child occurs only at a certain period of the menstrual cycle. The period from the eleventh to the fifteenth day after the onset of menstruation is considered dangerous, because at this time, the egg leaves the ovary. The rest are “safe”, but it’s worth remembering that you can’t say one hundred percent, and you can get pregnant during this period.
If a woman wants to identify dangerous days for pregnancy, the calendar is her best assistant. It should mark the beginning and end of the cycle. You need to follow the calendar for two years to find out about changes in your body and possible deviations of the menstrual cycle, if they occur. Only in this way can a girl know how to calculate safe days and prevent the fertilization of an egg. The beginning of the menstrual cycle is the day that spotting begins, and the end is the last day before the start of new periods.
How to calculate safe days? The calendar method is the most popular way that beautiful ladies use to avoid an unwanted pregnancy. To calculate, you need to know the shortest and longest menstrual cycle. Ovulation occurs on days 11-18, and to calculate the days of the “dangerous” period, it is necessary to subtract 18 from the shortest and 11 from the longest. It turns out: if the longest cycle is 30 days, then 30-11 = 19. Let the shortest be 26 days, then 26-18 = 8. Thus, the days from 8 to 19 will be considered a dangerous period. At this time, the probability of conceiving a child is the greatest, and on other days you can not be protected.
Naturally, the question of how to calculate safe days may arise monthly, because the onset of menstruation depends on many factors, for example, taking medication, general health, or stress. Therefore, many women can say that the onset of menstruation for them can be unpredictable. To determine a “safe” day, basal temperature (in the rectum) must be measured. Before ovulation begins, the temperature rises from 0.2 ° C to 0.4 ° C.
For many women, the cervical method is the easiest way to calculate your “special” days. It consists in monitoring changes in the mucous membranes from the vagina. From about the tenth and the eighteenth day of the cycle, watery mucus appears - it means that “dangerous” days have arrived, the probability of pregnancy is high. The calendar (if the girl leads it) can confirm that ovulation has begun.
But the symptom is considered the most accurate method, it includes all of the above methods. Only in this way the fair sex will know exactly how to calculate the days. When can I get pregnant? Such a question is asked by women who cannot conceive a child and use all these methods to determine the days of ovulation, when the conception desired for them may come.
