A woman’s ovulation period is an 8-day period, 4 days before and 3 days after the day of ovulation, which is the period of ovulation. If you are planning to get pregnant, you should arrange your sex life reasonably during the ovulation period, so as to increase the chances of getting pregnant, because the survival time of sperm after being injected into the vagina is 2-3 days, while the survival time of egg after being discharged without fertilization is about 24 hours, so you should arrange your sex life reasonably in order to increase the chances of getting pregnant. On the contrary, if there is no plan to get pregnant, you can have intercourse when you are not ovulating, so that you can avoid pregnancy, if you finally need to terminate the pregnancy, do abortion is still very harmful to the body. But the use of ovulation contraception must pay attention to is that the menstrual period must be regular in order to accurately calculate the ovulation period, otherwise the calculated ovulation period is inaccurate.
