A member asked:
My edd (based on utz) is 01.28.13. we had our intercourse on 05.01.12. is it possible that ultrasound edd will be inaccurate?
A doctor has provided 1 answer
Possible: Ultrasound dating is usually more accurate than calendar dating but is not 100% perfect.This date is only a few days less than you calculate, but can be a week off anyway.Edd's are always an approximation, and less than 10% deliver on the exact due date.
