Hi just curious because I know they say your 1st ultrasound scan is the most accurate.But im having a sec and I know they sched you one week advance and I want to make sure my LO is full term .I went to this free place to see if I was pregnant at 6 weeks and 6 days on July 3rd. And that ultrasound sounded off. That would have made my period May 15th and I know I have irregular periods but I actually remember when my lmp which was may 11th making my edd feb 15th or around that time.anyway they said my edd was feb 20th. Then I had a 19 week anatomy scan by a real ultrasound tech.Who I was sent to by my primary doctor they only specialized in doing ultrasounds. And they said they were pretty accurate and the due date they gave me was feb 17th and said I was actually measuring exactly at 19 weeks on Sep 23rd making my edd feb 17th and estimated conception may 27th which sounds about right and right on target.So my question is should I take the feb 17th due date since its a later scan or stick with the feb 20th due date.Because my primary doctor changed it to feb 17th based on the 19th week anatomy scan

Personally, I would take the earlier one. Earlier scans are likely to be more accurate, but it is affected by the equipment and the technician, etc. But even they with everything perfect they can be out by 3-5 days. In all honestly, I wouldn't be overly concerned about a difference of 3 days.

They can never be 100% accurate. Just as an example, my 32 weeks scan told me my baby was 4 weeks younger than I know she was because she was so small. There really is no such thing as 100% accuracy. To be 4 days out isn't unusual, especially if you have an irregular cycle. They don't base it on YOUR cycle, they base it on a standard cycle. Because you don't necessarily know exactly when you ovulated, it is quite possible to be out by a week or so.
