Just need opinions

Tiana

Hi my name is Tiana and I just have some questions. It’s weird because I’m on my period and when I was changing my pad I noticed a big blood clot that looked like it was in the shape of a tiny fetus and I don’t know what to think because I took a pregnancy test and it was negative. But I’ve been having pelvic cramps ever since I had the blood clot. So can someone help me out and tell me what they think? I was so scared I didn’t think to take a picture and I should have. Sorry.
