Nub and skull theory? Any experts out there?

[Elliegracie]

I have just had my 12 weeks scan. I have a potty shot and some side pics. Purely for fun we want to try and guess the gender. :-) now do I upload a pic if my scan?

I have one on my profile, i had to create a personal profile then upload it onto there as i dont know how to do links. You also have to put your settings so that other mums netters can view your profile.
Do you have your own ideas on the sex?
