The cause of vaginal bleeding after surgery for fibroids is determined by the type of surgery. If you have had a myomectomy for uterine fibroids, vaginal bleeding after this surgery may be due to poor contraction of the uterus or if the fibroids penetrated the endometrium during the surgery and the endometrium takes time to repair after the surgery. Therefore, this kind of bleeding can be observed on time as long as the amount of bleeding is not too much. In the case of total hysterectomy, vaginal bleeding usually does not occur more than seven days after surgery. If vaginal bleeding still occurs after seven days, it is possible that there is an infection in the vaginal stump and you must go to the hospital for examination as soon as possible.
