What makes doctors decide to go by ultrasound for edd instead if lmp? edd was changed from january 2 (lmp) to january 12 (u/s)
A doctor has provided 1 answer
Accuracy: Often times ultrasound performed in the first trimester is considered more accurate than the last menstrual period dating if the actual size versus the expected size is off by more than one week. This seems to be the case for you, therefore the due date was changed.

Why do doctors choose to go by ultrasound for EDD instead of LMP, even if LMP is known?
The doctors determined my due date from an estimated lmp, it was nov4 . Sept 16, i got an ultrasound that read oct25 which date is accurate?
My LMP was unknown so on 7/20 doctors said i was 8w3d by ultrasound & told me my due date is 2/26/13 & that i conceived on 5/22 is this correct?
When does it mean when a doctor considers the LMP due date and conception if the ultrasound is in a 7-10 day agreement with the lmp? Need an example
