Help me understand what happened at my dating scan!

[Teeki]

Sounds to me like she meant 3 weeks since conception, which would mean 5 weeks since lmp (your Dr would say 5 since lmp anyway). Because they assume every woman has a standard 28 day cycle and ovulates on day 14, they add on 2 weeks to the actual fetal age.

I think the same as Teeki - she was most likely talking about the age of the embryo, not the week of pregnancy which would be two weeks more. I think it all adds up alright if you look at it that way. Good luck xx

All good. I know answer. Sorry.
