12 Week 2 Day Scan Nub Theory Boy or Girl?

[whl]

Hi, I had my scan yesterday and I the baby was measuring 12 weeks and 2 days. I was interested to see if anyone had an opinion based on the nub theory if I was having a boy or a girl. I am new to all of this, so really don't know. I currently have a 2.5 year old son. Thanks for your help. Below are the scan pics.

I'm guessing boy since the end of the nub is angled up on the 1st pic xx

I'm not sure if what I'm looking at is the nub but maybe girl?
