Hi everyone! 
It's my first time here! I had my first scan recently at 12 weeks 3 days. It's my first baby so no idea what to expect yet! I heard recently about nub and skull theories to try and guess the gender of the baby early? I have tried looking at my scan pictures but I have no idea what I'm looking for and I can't see a nub on my pictures? It looks different in both pics! Can anyone point me in the right direction of what / where it is on my picture and what you think from looking at it / experience?
Thank you!
