After having an abortion, determine whether it is cleaned up by your own symptoms: 1. If you have symptoms of nausea and vomiting before the abortion and the symptoms are not relieved obviously after the operation, consider whether it is not cleaned up. If there is meconium residue in the uterine cavity and the blood chorionic gonadotropin level is higher than normal, there will be symptoms of nausea and vomiting. 2. If the vaginal bleeding time is more than 1 week, consider whether there is a possibility of uterine residue. The normal post-abortion bleeding time does not exceed 1 week and the amount of bleeding will not exceed the normal menstrual volume. 3. abdominal pain symptoms, abdominal pain within a short period of time after abortion is normal and may be caused by uterine contraction, if the abdominal pain time exceeds 1 week, consider the residual uterine cavity caused. If you have these symptoms, you need to review the ultrasound to determine the recovery of the uterine cavity, and if there is residue, you need to treat it with medication or uterine evacuation.
