A member asked:
As the margin of error for a scan that indicates a ga of 7w3d is typically +/- 5 days, is it possible for the estimated ga to actually be 6 days off?
A doctor has provided 1 answer
Yes, of course: In real life, 5 days and 6 days are essentially the same thing. Real life is never exact, so pregnancy-related dates are just estimates.

When you subtract 2 weeks from the ga provided by an ultrasound, does that give you the estimated fertilisation age or the estimated fetal age?
