I'm not sure how accurate the dating is. When I went I was 6weeks and 3 days, but they told me based on the size that the baby was 5 weeks and 3 days. But she also said that my due date wouldn't change :-s

And I could see the heartbeat which I didn't think you could see until 6 weeks??

Irena, your HCG levels look great. I am sure things are fine.
