If you have an abortion, it is not easy to get pregnant in this condition within one month of the surgery. Because after the surgery, the uterus and the endometrium are damaged, the endometrium is relatively thin and needs to be gradually repaired to return to normal, this situation is not suitable for the fertilization of the egg, and the human chorionic gonadotropin in the body, it takes about 20 days to return to normal, at this time is no ovulation. So one month after the operation, the chance of basic pregnancy is very small, and sexual intercourse should be prohibited within one month of the abortion operation to avoid infection. However, after one month of surgery, after a normal period, the uterus and endometrium will return to normal and the normal chance of pregnancy will be restored, so if you have sex, you still need contraception, and if you plan to prepare for pregnancy, it is recommended to start preparing for pregnancy three months after surgery.
