Nub theory? How accurate?

Question

How accurate is this theory? And when can you all see the nub? I am so confused when I look at the ultrasound

Answer

Nub theory is actually extremely accurate around 13 weeks. Usually at that time the nub has risen if it is a boy and is parallel to the spine if it’s a girl. It was right with both of my children and I had a boy then a girl. You must get the right angle of the sonogram tho - that’s the catch...

Answer

It is utter nonsense 
As is the ramzi theory

Answer

It’s been debunked.  Do it for fun if you want but it has a 50% chance of being correct.
