A member asked:
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?
A doctor has provided 1 answer
Yes: When estimating gestational age by using an ultrasound scan, 2 weeks are added to the fetal age (the fetal age is the fertilisation age).
