If it's a boy they can tell earliest 13 weeks. But girls are a little tricky.

Wow! Reading these comments just made me realize that gender guesses can be wrong even at 20 weeks! So how is everyone "finding out" at 12 weeks with the nub theory? Doesn't make sense to me

Heatherlynn, the place I'm going to does 4D. I didn't really want to do 4D this early but I feel like it will definitely be more accurate

Find a place that offers 3D ultrasounds I heard it's more accurate but who knows

Well if they say boy tomorrow I will believe it because Sneak Peek also said boy. But I also know sneak peek can be accidentally contaminated ?

Yes i was told i was having a girl... that girl came out with a penis so I'm pretty sure they got it wrong

I found out at 14 weeks, Monday gone! Some techs can mix up girl parts for boy. If you google the difference you will see how it can be mistaken. In saying that, I am definitely having a boy there is no doubt about it

Yes:-) my little guy was a "girl" at 20wks. They said his legs and umbilical cord (now that we know) were the "3 lines." Lol!

I plan on doing my nursery gender neutral anyway. And even if I do have a girl, I do not even like pink.

Yes i was told i was having a boy for my second pregnancy and well i bought everything for a boy and when i had my baby it was a girl

I was told boy at 20wks with baby #2, and she was NOT a boy. I thought my story was bad. Wrong at 30wks? That's crazy.

Barbiedoll, oh no! Did you have a bunch of girl stuff? A couple of my friends bought me boy stuff because of Sneak Peek saying boy even though I told them to hold off. I feel like it's a boy though, and even if it isn't my little girl will still wear it lol. I'll just put a bow in her hair.

I was told girl at 30 w with baby 3. HE was NOT a girl. And, he was the 8th one that week at the hospital I delivered in.

Both of mine were right at 16 weeks. Boy and girl.

I'll be 13w5d. But if they can't tell for whatever reason I can go back.

I found out with both of my kids at 13 weeks and they were right

I wish I had the patience to wait until 18 weeks ?

I don't think anything is ? until they are born lol. Depends on how early you get them done. I got mine at 15 and there was no mistaking it same as my son at 16 weeks.

Early ones are more likely to be wrong. After 18 weeks, they're highly accurate
