Low hcg

Stanita
Last week Monday  while in the Er I was told that my hcg level was 184 & that I'll probably miscarry. The attending dr told me to get a beta quantative on Thursday the 19th then told me that she was positive they wouldn't go up. Well on the 19th my hcg was at 517! I see the doctor weds and I'm hoping they've gone up more!!
