The review time of painless abortion needs to be determined according to the patient’s condition after the abortion, and there is no way to generalize the specific time, which should be decided according to each person’s physical recovery and symptoms of performance. If the abortion procedure went smoothly, with relatively little vaginal bleeding and no abdominal pain or only slight vague pain in the lower abdomen after the procedure, it is recommended to go to the hospital for routine ultrasound examination about 10 days after the procedure to clarify whether there is any tissue residue in the uterine cavity and to check the recovery of the endometrium and uterus. If, after the painless abortion, vaginal bleeding exceeds 10 days or the postoperative bleeding exceeds the amount of menstruation, or is accompanied by abdominal pain, fever and other symptoms, you should go to the hospital for a review at any time. Secondly, after the abortion, if you do not have your period for a long time, you should also go to the hospital for examination to clarify the situation in the uterus, whether there is cervical adhesion, and if necessary, HCG test to exclude whether you are pregnant. After the painless abortion, it is usually necessary to abstain from sex for 1 month, and to review the next period when it is clean. In addition, painless abortion is more harmful to women’s uterus, so it is recommended to choose scientific methods for contraception in the future, such as condoms, intrauterine devices, short-term contraceptive pills, etc., and to do abortion as little as possible.
