Girl or Boy --- Nub Theory or Skull Theory ?!?!?!

I am curious to know what others can see from this scan, 12 weeks and 2 days -- BOY or GIRL ?!?!? :)

Attachment 8668

I don't see any clues sorry.

I didn't see any either, So I thought I would post to get other opinions. Maybe I will have luck next scan :)
Thanks ! !

Good luck at your next scan, there's no nub visible here.
