I think I could be miscarrying but I didn't know I could have been pregnant, I am passing a couple of large blood clots and some tissue (not normal for me) like the pic above shows. I haven't done much cramping at all except when some grayish brownish gut looking tissue came out. My question is when should I see a doctor, its very hard ffor me to get to one and I want to be certain, also if I took a urine test would it still show positive if I were?
