I've been having SEVERE pain in my abdomen for the past ~10 days. It feels like a mix of bad gas and period cramps, accompanied by heavy bleeding. I saw my doctor, and she wrote it off as "stress." Today, I was changing my tampon and out fell a clot the size of the palm of my hand. I've never had anything like this before. It was one big, thick clot with a membrane-y like texture and look? Idk what's going on. Is there a possibility that I was pregnant and didn't know it and I'm miscarrying?? Or is it just a ridiculously heavy period? I've never had anything like this before.
