After medical abortion, the uterine lining can be shed down together with the pregnancy capsule, and it should not be more than half a month after medical abortion at the latest, because if more than half a month to do ultrasound, there are still residues in the uterine cavity, which may be the meconium when pregnant, this meconium must be stripped off, otherwise it will cause incomplete abortion, that is, irregular vaginal bleeding will occur, and serious bleeding will also occur, so in the drug If there is not much bleeding after abortion, it is necessary to go to the hospital for examination two weeks after abortion. If the uterine cavity is clean, it means that the abortion is complete. If there is still residue in the uterine cavity of more than 1cm and there is vaginal bleeding, the uterus must be scraped immediately. If it is within 1cm, you can take the medication temporarily for observation and wait until the next menstruation to do ultrasound, if the menstruation is clean and the residue is cleared, there is no problem. If the residue is still there after the menstruation, the uterus must still be cleaned.
