13 weeks

How many were able to tell what you were having at 13 weeks? I have an ultrasound today and hope to find out! :) thank you in advance

I found out at 14 weeks with my son, they can check but it's not guaranteed at 13 weeks. The parts are starting to differentiate at this stage, so it just depends on your baby. Around this time girl parts are starting to retract into the body and turn into ovaries and what not. All babies start with the same parts and then they change into testes or ovaries and so on. Good luck!

I just had an ultrasound last week 13w4d and my doctor said there is no way to even tell this early by ultrasound. Both parts still look the same in a boy or girl.

Really? My doctor told me 75% he has been able to tell

I heard there was a nub theory? I wondered if that is what they go off of to tell? but maybe my doctor wont because it's not a guarantee. Baby had it's back in the ultrasound so even if I wanted to know there would be no way this time. Definitely look into the nub theory before you go.
