I have my second scan today and I'm officially 8+3 but my scan measured bubs at 8+6 and then 9 weeks. My OB kinda made a comment about "see how the NT scan goes" and now I'm worried that this is a bad thing or could mean something bad. My scan 2 weeks ago bub was measuring only 1 day ahead of what I was. I know my dates are accurate as I know when I OV'd and know my LMP dates.

Any explanations or similar stories..
