Doctors generally do the "anatomy" scan between 18-24 weeks...But it depends on the doctor. Beginning at 16 weeks you can get a 3d/4d ultrasouns at one of those private place and find out the sex.
I found out at 16 weeks, I'm having a boy too. My lil cooperated for a change since then he hasn't lol ~d
I just had a u/s at 15w and the dr. did try but the unbillacord(sp) was in between the legs. I think it all depends on the dr. and or u/s tech on how good they are. But the earlyist is 13-14weeks.
I found out at 16w6d that I'm having a boy!
I was told that the sex organs don't even differentiate themselves until after 14 weeks. So it's still way too early. I just found out last Tuesday at 17 weeks 3 days that I was having a boy.
i just had an ultrasound 13 weeks and 4 days they told me it was too early
i found out i was having a boy at 17 weeks!! 10 weeks is just a little too early!
13 weeks is the earliest.
