The 'nub theory'

My sister-in-law introduced me to the nub theory, where the angle of the nub in your 12 week scan could tell you whether you're having a boy or a girl.

It seems a little too good to be true though and even after staring at my scan pic for ridiculous lengths of time, I'm still not sure!

Here's the website explaining it all:

Have a read, then tell me what you think my little squid is gonna be! Maybe you'll be better at it than I am.
