If you need to have an abortion after pregnancy, when you are pregnant for 35 ~ 49 days, you can choose medical abortion when you are diagnosed as normal intrauterine pregnancy by B-ultrasound. However, medical abortion may have the possibility of incomplete abortion. In this case, it may be necessary to perform curettage surgery. If it is more than 49 days, you can have an induced abortion operation within three months of pregnancy. It is more appropriate to have the most abortion operation within two months of pregnancy, because the pregnancy time is short, the embryo development is small, and the gestational sac can be clearly seen during the operation, so that the success rate of the operation is high, the harm to the body is relatively small, and the postoperative recovery is relatively fast. If the pregnancy time is too long, the only way to terminate the pregnancy is to induce labor, which is harmful and painful to the pregnant woman. If you need to terminate pregnancy, you must choose a regular hospital for abortion. After abortion, you should pay attention to rest, avoid catching cold, pay attention to personal hygiene and avoid infection. Sleeping together should be prohibited within one month after abortion. If vaginal bleeding lasts too long or blood volume exceeds normal menstrual flow after abortion, you should go to the hospital for examination in time.
