A woman’s ovulation period is a period of 8 days, 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 sex during the ovulation period to increase your chances of getting pregnant, because the sperm survives for 2-3 days after being ejaculated into the vagina, while the egg survives for about 24 hours if it is not fertilized, so arrange sex reasonably to increase your chances of getting pregnant. On the contrary, if you are not planning to get pregnant, you can have intercourse during the non-ovulatory period so that you can avoid pregnancy, and if you end up needing to terminate the pregnancy, having an abortion can still be very harmful to your body. But the use of ovulation contraception must pay attention to the fact that menstruation must be regular in order to accurately calculate the ovulation period, otherwise the calculated ovulation period is inaccurate.
