Can someone please tell me

What the nub theory is??? I keep seeing it on threads but have no idea!

It's the theory that you can tell baby's gender by looking at the 'nub' (the protruding bit between the legs that both genders can have at 12-14 weeks) and which way it is angled. I think it's 30 degrees and up is supposed to be a boy (relative to the baby's spine) and below that is meant to be a girl. But there's not a lot of scientific evidence for it and the nub isn't always visible. Hope that made sense!

I see! Very confusing!

Thank you
