After having rough sex I had some vaginal bleeding. It stopped for the most part but there is still a little blood, more pink, 10 hours later. I had a hysterectomy 3 years ago. Also have some minor abdominal pain. The abdominal pain is minimal. No other discharge. It has been about 12 hours since the intercourse. I don't think it is anything serious but have never had that happen before. How long should I wait, what other symptoms should I look for, how will I know when it is something that won't take care of itself or that I can't take care of?
