No: For pregnancy dating purposes, the earlier the pregnancy was dated the more accurate the date. The date given during an ultrasound is based on the machine comparing with national averages, and as the pregnancy progresses there will be more variability. Stick with your original due date.

Same due date: If an ultrasound is only off by two days - your due date remains the same.
