In the event of an unplanned pregnancy, if the fetus is not wanted, there are two clinical forms of abortion: medication and abortion. For early intrauterine pregnancies within 49 days of menopause, medication abortion can be considered. However, there is a possibility that some of the abortions may be incomplete, and its biggest side effect may be vaginal bleeding at a later stage. Early intrauterine pregnancy within 12 weeks of pregnancy can be aborted. The best time to perform an abortion is between 45 and 55 days of pregnancy, when the size of the gestational sac is not too small and the abortion is relatively appropriate. If the size of the gestational sac is too small, it can lead to incomplete abortion, and there is also a possibility of aspiration and leakage. If the size is too big, on the one hand, the risk coefficient will be relatively large, on the other hand, the bleeding during the operation will be relatively large, and the recovery after the operation will be relatively slow. Therefore, if it is abortion, it is better to be between 45-55 days of pregnancy. Whether it is artificial abortion or medication abortion, there are certain adverse effects on the health of the body and the uterine lining. After the operation, you need to routinely carry out anti-inflammatory and blood circulation, regulate menstruation, nourish, regulate and other measures, pay attention to rest, eat a light diet, prohibit sexual intercourse within one month, and regularly review the ultrasound to observe the recovery of the uterus.
