Wondering if others have had a similar experience:

First day of last period was February 14 (making my due date November 21). Got a positive pregnancy test about 4.5 weeks after start of last period (didn’t take one till I missed my period).

Went in at 8 weeks for ultrasound and OB said baby was measuring 5 days behind (but my first baby measured a week behind my whole pregnancy and was on the low end of the growth chart his first year, and he came 3 days after his due date naturally, so the Dr said that I probably just make small babies).

I had my anatomy scan today at 21 weeks, and the ultrasound tech said that my baby measured at 19 weeks in every category and pretty much insisted my due date was wrong, but then said that the first ultrasound is the most accurate in determining gestational age. Baby was 11 oz.

So my question is has this happened to you? Did your doctor change your due date? My follow up is Monday and adding two weeks kind of just made me feel so down. But I also felt like she contradicted herself when she said that my due date should be December 1 but that all of the ultrasounds after the first one aren’t considered accurate for determining age.
