whats the nub therory?

[MYPRINCEssB]

so I feel clueless what is the nub theory, and the skull theory?
I have a scan on Friday and will be 11 weeks
I feel its going to be a boy
and inteligender gender predictor gave me a boy result
I would like to learn all I can before my scan
thanks

thanks I def saw a nub but didn't get a pic of it but I did get some good ones of its skull so could some one tell me what the scull theory is too

This is very good to explain the skull theory or to give you comparisons.

The skull and nub theory are more accurate at 12 and 13 weeks. I feel girl looking at your pics but I'm no sonographer. Good luck.
