If vaginal bleeding occurs after half a month of medication abortion, this situation is mainly considered for the following reasons: 1. Consider the possibility of incomplete abortion, because there are residuals in the uterine cavity, the vagina will continue to bleed, or accompanied by abdominal pain and discomfort. To further clarify the need to review the ultrasound, if the ultrasound found that there are strong echoes or slightly strong echogenic masses, consider the possibility of incomplete abortion. If the residue is not big, you can take oral medication to promote the discharge of the residue, if the residue is larger than 2cm, it is recommended to clear the uterus.2. If you are overworked after the abortion, or do not pay attention to hygiene, or premature coitus with uterine cavity infections, resulting in poor uterine regeneration, you will also have this symptom or accompanied by abdominal pain and discomfort. You can take motherwort granules to promote uterine contraction and help the uterus recover, as well as oral anti-inflammatory drugs to prevent infection, and mainly bed rest.
