Two EDD..Which one?

[merideffi]

I had a somogram when I was 8 weeks I though,  come to find out I was 9 weks and that put my due date on Dec 7th, I had a another somogram when I was 19 weeks almost 20 weeks and from the measurements of the baby The sonogramer said my due date should be Nov 23rd. I'm wondering which one to go by?
I'm hopeing for the 23rd but don't really know. My Doctor is giving my one on the 13th of this month so I'll see what he says next.

Thanks,
Mer

Is it normal for your EDD (LMP) due date to be 3 weeks different from you EDD (AUA) due date.  According to my sonogram they are 3 weeks apart so one due date is march 6 and one is march 25.  That seems like a big difference!!  Has this happened to anyone else?

I had multiple due dates with both my kids. I had at one time I think 3 for my son and 3 for my daughter. So early or late they dont care. Your body and baby knows when its ready.. I would say as you get close to your first reccomended due date start preparing. Good luck..

I have heard that the further along you are, the less accurate the sonogram measurement is for determining due date.  I'm at 21+ weeks, and my doc doesn't even measure the baby any more when doing ultrasound, because as the baby gets bigger, it is too inaccurate due to the way the baby is lying in the uterus.  Please also keep in mind that knowing an exact date of conception doesn't guarantee a specific day for delivery -- babies come early, babies come late, they don't care what doctors or statistics say.
