Women can have sexual intercourse after a month of abortion. Since abortion and medical abortion can damage the endometrium and ovarian function of women, menstruation after abortion is not normal and is often delayed. If the patient does not have a period within one month after abortion, it is recommended that the patient should not have intercourse and try to have intercourse after having a period. If the patient has intercourse before her future period and a persistent delay in menstruation occurs, the possibility of another unwanted pregnancy should be highly suspected in this case. Because the ovarian function is damaged after abortion, ovulation is disrupted, so it is not easy to grasp the ovulation period, and it is easy to have an unplanned pregnancy, and another unplanned pregnancy is more damaging to the patient’s body. If you have had a normal period one month after the abortion, you should also pay attention to contraception in the next 2-3 months to allow sufficient time for the endometrium and ovaries to recover and not to get pregnant again in a short period of time.
