Induced abortion in the third trimester of pregnancy usually involves some pain. Usually in the third trimester, the fetus is basically already formed and bones are forming. At this time, the development of the fetus is relatively large, and it is necessary to carry out a medication abortion first, such as applying Mifepristone or Misoprostol under the guidance of the doctor to induce abortion. At the same time, it is necessary to take measures to stimulate the uterus and cause contractions to enable the fetus to move down and be delivered, and the uterine contractions will cause pain. Because the fetus is already formed in the third month, it is necessary to dilate the uterine opening to 3~4cm to deliver the fetus during induction of labor, and there will be a certain amount of pain during this period. If there is intolerable pain during induced labor, the pain can be relieved by methods such as intrathecal anesthesia. In addition, you need to take care of nutrition and ensure personal hygiene after induced labor. If there is any abnormality such as worsening of pain and blood flow, you need to go to the regular hospital in time.
