Common: Bonnie, it is very common to revise the due date based on ultrasound evidence, because it is much more accurate than the first day of your last period. Why they didn't mention it earlier, I can't say, but remember that guessing a due date is an inexact science. Only 5% of babies are actually born on their due date. Hope this helps!
