Under normal circumstances, there may be a small amount of vaginal bleeding after abortion, but it will not exceed the amount of menstruation, and the duration will not exceed 7 days. If it has been 15 days since the abortion and there has been vaginal bleeding, it is necessary to consider whether there is intrauterine residue or the possibility of poor uterine regeneration or infection, then you need to go to the hospital for ultrasound examination to clarify the uterine regeneration. If there is intrauterine residue, you need to carry out purging treatment on the basis of anti-inflammatory treatment, and if the ultrasound examination of the uterus is not good, you need to apply drugs such as hysteronin and motherwort to promote uterine contraction treatment. If it is considered to be caused by inflammation, anti-inflammatory and hemostatic treatment is needed. If no problem is found after examination, HCG should also be checked to exclude trophoblastic diseases, etc. Of course, the incidence of such diseases is relatively low, so it is less likely.
