If they didnt do a dating scan then the edd would be based off of the first day of ur last menstrual period, they dont calculate it from ovulation or 28 days cycles, just lmp.

So my ultrasound had a edd of 1/22/15 but the doctor said the 16th of January. I had a 9 week ultrasound to confirm my pregnancy .

U could go by either really. My first ultrasound was 4 days behind my lmp but my ob stuck with my lmp becuz theres always a variance in the first bit. That was my 8wk dating scan and by my 12th and 20wk scans, she was consistently ahead in growth. Becuz ur using an app, its hard to know exactly when u O'd/conceived so I would just stick with what the ob says and make a mental note of what the scan said. Have u had any since? He may have just been off to a slow start like mine was.

Yes I have had plenty of scans since and a detailed one to check his growth and nothing has really changed . I just wanted to make sure we were on the right track with everything . I have a really small belly for 7 months and I was a little worried but everything looks good.

Awww dont worry too much, ur belly will get bigger in no time, u probably just carry pregnancy very well.
