A member asked:

What is best to go by edd lmp or edd ultrasound?

Dr. Bruce J. Stringer answered

Specializes in Radiology

Depends: If the first ultrasound was done in the first trimester, especially 7-10 weeks, there is no doubt that the sono is best. After the mid 2nd trimester it's anyone's guess.
