The last day of menstruation for intercourse is generally not pregnant, because menstruation is not completely clean, the lining is still peeling, even if the intercourse is not able to implantation, and menstruation is not ovulation, there is no way to combine with the mature egg, so there is no way to conceive. However, it is not recommended to have intercourse when the menstrual period is not completely clean because it can cause the sperm to be planted into the bloodstream and cause positive anti-sperm bodies, which will have a certain impact on the future conception, and it can also delay the end of the menstrual period, which will cause more than just menstrual dribbling, and it can also cause abdominal pain or high fever, so it is not recommended to have intercourse when the menstrual period is not completely over even if there is no chance of getting pregnant. Even if there is no chance of pregnancy, try to have intercourse 2-3 days after the end of your period.
