16 weeks is the earliest that it xan be. Totally accurate. Anytume before that all babiea look like boys.
I found out at 15 weeks confirmed at 27 weeks
I'm going in at 14w+3. I know that doesn't answer your question now, but I'll post about it if we can tell! My friend found out at 15w
I had a 4d u/s at 13 weeks and she either wouldn't make the assumption and tell me, or she really couldn't didn't know. I couldn't tell which it was lol
Unless u go get 3d ultasound ive seen them say 14wk
Most probably n accurately by 18-20 weeks
Ive read on here some women on here have found out at 16 weeks.
but it also depends on the ultrasound technician and how new the machine is to get a good result.
