Easy pregnancy
The ovulation date of women is usually about 14 days before the next menstrual cramp. Sex is more likely to lead to pregnancy in the days when eggs are discharged. In order to determine this period more accurately, we call the first 5 days and the last 4 days of ovulation day, including ovulation day, *** 10 as ovulation period. Ovulation period is also called susceptible pregnancy or dangerous period.
Safe period before ovulation
The day from the end of menstruation to the beginning of ovulation is a safe period before ovulation. During this period, the risk of pregnancy for women is low. However, it should be noted that due to environmental changes or emotional fluctuations, women's ovulation date may be advanced, which will shorten the safe period before ovulation and reduce its safety.
Safe period after ovulation
From the first day after ovulation to the day when the next menstruation comes, it is a safe period after ovulation. Generally speaking, the safe period after ovulation is safer than that before ovulation. Because in a menstrual cycle, the probability of ovarian ovulation twice in a row is very small. So the safe period after ovulation is relatively more reliable.
