What is the reason why menstruation has been unclean after drug flow

Compared with abortion, there is no surgical trauma, which is its advantage. However, abortion often leads to vaginal bleeding for a long time, even for a month, until the next menstrual cramps. This situation is not uncommon. Because the main discharge of drugs is the gestational sac, decidua around the gestational sac, generally can not be completely eliminated by drugs, need to slowly absorb, this process is very long, sometimes there will be vaginal bleeding. Therefore, if the drug flow has not been clean, do not worry too much, to do B-ultrasound examination, if B-ultrasound examination, there is no obvious intrauterine residue, general oral motherwort and other uterine contractions, promote decidua can be discharged. Of course, in individual cases there will be obvious uterine residue, then need to clear the palace again, this situation is rare, generally around 10%.
