Currently there are several ways to terminate pregnancy in our country, and it is recommended to choose the safest and suitable way for you according to medical advice to reduce the damage to your body. One of the best times for medical abortion is when the pregnancy is less than 49 days, that is, within one and a half months after menopause. This is because the uterus is not too big, the pregnancy tissue is not too much, and the fetus is relatively small. Relatively speaking, the risk of having a medical abortion within the best time for medical abortion will be relatively lower. Therefore, for pregnant women who are 40 days pregnant and have no contraindications, if they want to abort, they can have a medical abortion. Although the risk of medical abortion is relatively small, it still needs to be carried out under the guidance of a doctor and should not be carried out without authorization to avoid more serious consequences. If the doctor will explain in detail the method of taking the medication, its efficacy and possible side effects, the pregnant woman can only use mifepristone after she agrees to take it, either in a single dose or in parts within 3 days. After three days, a prostaglandin tablet is placed in the vagina or misoprostol is taken orally to promote intestinal peristalsis and uterine contractions, to facilitate the expulsion of pregnancy tissue, to complete the abortion and to avoid residual pregnancy material. In addition, the patient should be closely observed after the administration of the drug, paying attention to blood pressure, pulse and side effects of the drug, and checking the time of expulsion of the fetal sac, its size and the amount of bleeding. If there is active bleeding or incomplete miscarriage before and after expulsion of the fetal sac, contraction agents may be given or surgical removal of the uterus may be performed to remedy the situation.
