BG that is excellent that all went well on your scan. Congratulations!
The measurements are all just estimates, so you always expect a small variance.
With my DD my U/S showed she was 4 days younger then what I expected based on my LMS. The obst just made that my new EDD and we went by that after the 6 week U/S.

Well what a start to a weekend! I am happy things went well.

Possums, I hope you U/S is just as perfect!
