My friend thinks she has had a miscarriage. She has been bleeding for 3 days but yesterday she was bleeding really bad and had some small blood clots and one big one that she said felt like it just dropped out of her. She told me she might be having one because she lifted a 60 lbs bow and felt something ripped and she grabbed her stomach cause it shot sharp pains. She didn't really think she was pregnant because her period were not normal. Did she have a miscarriage?
