I started bleeding yesterday, I went to the ER, and I had my HCG levels tested, Vaginal US, and my cervix checked out. My HCG levels were 87,000 my US showed that the babies heart beat was 160, and my cervix was closed, so all was ok. Now here comes the weird part, I was told I was 9 weeks, 2 weeks ago by my doctor, the US said I was 7 weeks. When I go back to when I would conceive to be 7 weeks, that makes it around the day I found out I was pregnant, so that is not right. Could the baby be 4 weeks to small, adn still be ok?
