So my entire pregnancy I've been going by my due date, March 16th. However at 34 weeks I had an ultrasound and they said I was measuring two weeks ahead.. I didn't think much of it. Well I went to L&D a couple days ago for some contractions (false) and they said my due date is recorded as March 5th! Putting me at over 38 weeks, almost 39. It's weird to me to have a change in due date so far ahead. Has anyone had this happen? Did your baby come earlier than expected?
