Hi, I am having the opposite feeling. I am about the same as you (due 9.12.08) after 15 goes at IVF. Had a miscarriage last year, heart stopped beating at 7 wks. My HCG was 80 at day 14 and then after some spotting, had another blood test at day 20 and it was 951. All the web sites say this is good, but doc said it was only ok and i am going for early scan this Friday to see if everything ok. So I would say your HCG is fine, but I agree with the others......twins????? or more?????
