From what I've learned so far in my classes it is a guess before 16 w because baby is so small it's hard to tell if it's a penis or swollen vagina and some boys don't start protruding until late in the 15 w.
I was told at 13 weeks as well with a 2d/4d scan:)
16 weeks is when they can tell. But most doctors wait till 20 weeks since they do the scan then mostly.
Well you got lucky then lol most won't even take a guess until at least 16 weeks. It's most accurate t 20+
I was told at 15 weeks but got confirmation at 20
BABYDUE07182013 - when I got mine done they said it was 90% of the baby being a girl :)
I was 18 weeks. If they tried to look now it would just be a guess
I found mine out at 13 weeks :) it was a 3d /4d ultra sound . I go in tomorrow to confirm !
20 weeks is when I found out also. My dr said before then the chances go way up about it being wrong.
16wks is the earliest for a more accurate result. Im 13+4 and have an ultrasound on about a week they can guess at the gender but im gonna wait til I get a 3d done at 17wks.
