nub theory. 12w5d. 😊

Me
Went for my NT scan today. 
Baby is doing great. It was sleeping on its stomach and was being cooperative for the ultrasound but didn't want to show us it's baby parts until the tech aggravated it enough to show us. 
We got to see something big between the legs, and the tech was calling it a "he" before we checked. We think boy and tech said she was 90% postive we're having A BOY! ❤️😍
We discussed the nub theory and my tech stands behind that theory as being truthful, what do you guys think?
