A woman is able to ovulate normally in order to have intercourse and she is most likely to get pregnant when she has intercourse during ovulation. The time period when ovulation occurs is mostly 14 days before the next menstrual period. If intercourse does not take place during a woman’s ovulation period, after intercourse the male sperm will enter the woman’s reproductive system and stay for about 24-48 hours before dying. So women can project their ovulation time by corresponding methods, as follows: 1. Basal body temperature monitoring: The basal body temperature of adult women fluctuates with the menstrual cycle, women’s body temperature is always low before ovulation and fluctuates less, the basal body temperature will suddenly decrease on the day of ovulation, and after ovulation the body temperature will rise significantly by about 0.3℃-0.5℃; 2. Cervical mucus monitoring: In the first half of the menstrual cycle, the The cervix does not secrete mucus and the vulva is very dry, after that it secretes a small amount of sticky and opaque mucus. When ovulation is imminent, with the emergence of the peak of estrogen, the cervical mucus becomes thin, transparent and clear, and the amount increases, and when touched by the fingers, the phenomenon of pulling silk is found, which is the ovulation period; 3. This is calculated by taking the first day of the current menstrual cycle as the base point and counting backwards in days. As mentioned above, ovulation is the most fertile time for women. After a woman ovulates, she no longer has the ability to fertilize her eggs, and naturally, she cannot get pregnant. If we analyze the age of women, it is generally easiest to conceive between the ages of 20 and 30.
