Couples who want children should learn to master the ovulation period of their wives. Only when the eggs are discharged and the sperm are combined can you get pregnant.
The ovulation period of women with regular menstrual cycle generally occurs on the14th day from the first day of the last menstrual cycle or on the14th day before the next menstrual cycle. This method of calculating ovulation period is not suitable for women with irregular menstrual cycle. If possible, it is best to monitor ovulation by B-ultrasound with ovulation test paper on the first 10 day of menstrual cycle.
Sperm and eggs can survive for 48 hours after ovulation, so couples who want to get pregnant should arrange sex a few days before and after ovulation.
