One month of pregnancy can be aborted by medication. Medication abortion requires two kinds of drugs, firstly, drugs to inhibit the development, and then drugs for contraction to promote the expulsion of the embryo, most patients will abort within 3-7 days after taking the medication, the woman’s body is weaker after abortion, so she must pay attention to rest and supplement nutrition. The success rate is lower than that of surgery, and surgery is still needed after a failed abortion. However, patients with serious diseases are not recommended to have medical abortion, which will cause more harm to their bodies. If the abortionist strictly follows the surgical procedure, its complications are less, but if the abortion is not complete, it may affect the normal contraction of the uterus and lead to increased bleeding. In severe cases, it may cause heavy bleeding, which may lead to anemia and shock, in which case emergency blood transfusion and surgical curettage to stop bleeding are required.
