The most obvious manifestations of a clean abortion include the cessation of vaginal bleeding and the disappearance of abdominal pain. Generally speaking, after a medical abortion, as there are more residual substances in the uterine cavity, the uterus needs to contract continuously to expel the evil dew out of the body, so there may be vaginal bleeding symptoms, accompanied by obvious abdominal pain. If the abortion is clean, there will be no bleeding for a period of time and the abdominal pain will disappear. If you want to confirm whether the abortion is clean or not, you need to wait 30-42 days to see a doctor for ultrasound examination, through ultrasound can check the residual material inside the uterine cavity, if there is no residual material present, it means that the abortion is clean. Usually need to pay attention to personal hygiene, keep the pubic area clean, to avoid infection.
