A member asked:

How far off can dates be at an early ultrasound to be worried? i ovulated around day 16-17 but i calculated 6 wks a d 5 days. scan showed 6wks

Same thing: The ultrasound is only accurate within plus or minus two weeks. The ultrasound and your calculations are merely "estimates" of gestational age at this early point.
