Accuracy of dating scans

How accurate are dating scans around weeks 5 and 6? I slept with guy A on August 2nd and guy B on August 10. My dating scan that I had done on Sept. 2nd said I was 5 weeks and 2 days. But the lady who did the scan said it could be off by up to a week so she recorded on my file that I was 5 weeks and 6 days. I don't know when my lmp was. I was just curious if you had any advice on whos baby it might be.

What does it say on the face of the scan itself?  Does it give an EDD?

I thought that was weird! The scan most definitely said 5 weeks 2 days. And then on my records it says 5 weeks 6 days. I figured she knew what she was talking about but she didn't seem to want to answer my questions about my situation. It just all seemed weird.

Are you sure that what happened is that she told you that you were 5 weeks 2 days and wrote down 5 weeks 6 days?  That is a very unusual thing to do.  If I were you, I would go to some trouble to get the films read again by the doctor and explain that you need an exact estimate of how far along you are.
