Nub theory?

Question

Can someone please explain nub theory as I don't get it lol 😅 here's my scans from yesterday 11 weeks 5 days

Answer

I can't see the nub in your pictures but if you do see the nub boy the nub is at a 90  degree angle, girls nubs are parallel to the spine or straight out between legs. Your picture by skull theory your baby is a girl. Round for girl odd shaped of boy

Answer

That's a girl 💯
