A member asked:

Is my 8 weeks and 3 days ultrasound my actual due date ? it was 10 weeks and 3 days before ultrasound

A doctor has provided 1 answer
Dr. Douglas Lawson answered

Yes: If your US said 8 weeks 3 days and your LMP said 10 weeks 3 days, then that is more than 7 days difference and the US due date would be used.
