I had a natural miscarriage two weeks ago when I was 15 weeks along. The bleeding stopped shortly after it happened. Last night, I started bleeding very heavily and cramping. I went to the ER then, but they didn't tell me much, just to follow up with my regular OBGYN. I can't see him for two weeks. Now, I have a rash on my chest and neck. Could this be related? What's going on?
