Girl or boy 13 week scan? Please guess for me based on nub or skull theory

[starbabyx4]

Hi,
Please could anyone take a guess at whether I'm having a boy or a girl based on the skull or nub theory? Please see attached 13 week scan pictures. Thank you so much for your guesses!

UPDATE. THIS IS A BABY GIRL!!!!!! IM NOT SURE HOW TO EDIT THE TITLE

I'm not sure i can see the nub shot it may be the leg, pure guess would be girl xx are you going to find out what you're having? X

Thanks for your guess I'll try and circle what I believe is the nub and post another picture. I've had a few guesses that it's a girl due to the angle being parallel with the spine but I'm not sure whether the full nub is shown. I'm not too sure if I'm going to find out or not yet x

My friend studied the paper copies and thinks that this is the nub

I would guess boy - did you sway or have a preference?
