My wife had surgery about 9 weeks ago, D&C, with no polyp noted, despite a scan that indicated otherwise. She has Von Willibrands, and is taking meds for RA. She has been bleeding heavily to the point of hemorraging, and it builds-up and then stops for :40 mins, then releases again. The uterus is pro-lapsed. No cancer has been noted. Is this an emergengy due to the type and condition of the bleeding, & should we call an ambulance?
