🚨TMI PHOTO🚨 Hello ladies I'm stuck in a dilemma. On Friday I passed what I'm most certain was a fetus. I had pregnancy symptoms similar to my previous pregnancy. When I tested a home test it was negative. Then Friday I passed the fetus. I was shocked and confused. I went into urgent care Saturday and showed them the picture and told them the whole thing. They seem certain it was a miscarriage but when they did my blood work they said there was no HCG in my system and concluded it wasn't a miscarriage. They couldn't tell me what the little pink thing was that I passed. 
When I called my OB they refused to see me because of my blood work. I still feel pregnant even though I'm bleeding and now my right side on my pelvis hurts. 
Has this happened to anyone else before? Please tell me I'm not crazy. I'm so emotional from everything.
