If you want to terminate a pregnancy in the third month of pregnancy, it is a remedy for unplanned pregnancy due to contraceptive failure, or it can be terminated due to disease that makes it inadvisable to continue the pregnancy or to prevent congenital malformations and hereditary diseases, you cannot do traditional abortion (abortion for short) at this time. Because of the large size of the gestational sac and embryo, in this case, hospitalization is required for the operation. Traditional abortion cannot be performed with a suction tube, and there are also risks associated with forceps scraping, so a combined treatment of medical abortion plus a curettage is usually required. After hospitalization, you need to improve the relevant auxiliary examinations before the operation, such as ultrasound, blood routine, coagulation test, white belt routine, urine routine, electrocardiogram and other related examinations. If the results are normal, you can take the medication for medical abortion first under the guidance of a professional physician, wait until the placenta is expelled, and then perform the clearance procedure. After taking the medicine, there may be symptoms such as stomach pain and vaginal bleeding, and it usually takes about 3 days to take the medicine. After taking the last medicine, the embryo will be expelled in about half a day, and the doctor can do the operation to clear the residual placenta and fetal membranes in the uterine cavity, and you can be discharged after taking a few days’ rest as prescribed by the doctor. After discharge from the hospital, you should pay attention to rest, do not engage in strenuous activities, do not have intercourse within one month, and avoid getting pregnant again within six months.
