Dating?

Question

I went for an ultrasound today thinking I was 11w6d based on my 7 week ultrasound.   On the ultrasound from today it says 12w 1 day in the corner.  Is this what I should go by?

Answer

No go by dating scan

Answer

Nope they won't change your due date unless you measure more than a week off. 
LMP said 5/9
Dating scan said 5/13
NT scan said 5/7.

Answer

Earlier scans are more accurate. I’d go by your original scan. My dates are usually a few days off in either direction so I went with what my original dating scan said.

Answer

No. I’ve had three. First was spot on with missed period. Second I measured 3 days ahead. Third 2 days begins.  He said it’s normal to be off up to 5 days in either direction and even more in 2nd trimester.
