The first half of the month of abortion can not cohabit. Because the drug abortion on the uterine lining has damage, the uterine lining repair time needs at least one month, so must be a month after the menstrual period is clean before intercourse. Some people may have normal ovulation half a month or so after a medication abortion, and if you have intercourse at this time, you may get pregnant again. If there is no fertility requirement to get pregnant, abortion is needed and the damage to the uterine lining is severe. In some cases, half a month after the abortion, there is a good chance that there will still be an incomplete abortion or a possibility of leaking and bleeding. So, at this point in time, you need to go to the hospital for an ultrasound to see how the uterus is recovering and if there is any incomplete abortion.
