I stopped regular periods a few months ago. I've been rear-ended by another car twice in the last two months. Both times, I had spurts of blood from my uterus (following the impact of the cars that hit me., I tink). The blood was not bright red, and I have been diagnos3d with endometriosis in the past. I have had two endometrial ablations. One tis year, and one about four years ago. Any cause for concern?
