A member asked:

Why are my ultrasounds always a week ahead of my period gestational age?

A doctor has provided 1 answer

Either you are due: A week sooner or your baby's weight is over the 50th % which is not uncommon please discuss with your OB and when you do an ultrasound past 20 weeks it can be + or - 1 week.
