If the sperm comes out during intercourse, it is possible to get pregnant if the woman ovulates. Although the sperm comes out, there is still a small amount of sperm in the body, which can also cause pregnancy, but the chance of pregnancy is reduced. If a woman has a safe period, even if a large amount of sperm enters her body, she will not get pregnant because no egg is discharged during the safe period and the sperm and egg cannot unite. It is better to calculate the ovulation period according to your menstrual period. If you have intercourse during the ovulation period and do not intend to get pregnant, it is better to take the emergency contraceptive pill in time. Note that the emergency contraceptive pill should not be taken often, not more than 3 times a year, it is very harmful to the body and can easily cause menstrual disorders and fertility. But if in the safe period do not worry, usually must do a good job of contraception, you can use condoms or contraceptive ring, etc..
