Skull/nub- please guess boy or girl?

This SG is 12 week 5 days. Please guess boy or girl. Sorry but wait till 20 week scan is killing me.

I appreciate it much.

Anyone please guess...

I'm new to this but I can't see a nub. As far as skull goes it looks girly to me. But like I said I'm new to this :)

Bobster-Thank you for your input.

No nub that I can see.

Maidentomother- Is is possible for you to guess based on skull? I'll try to upload some more pictures.

I would agree a girly skull but no nub visible

Girls- thank you for your input. I tried looking some nub shot in digital media but tech never gave one. Sorry about that. Please guess on Skull theory.

Any more guesses?

I'd of said boy but that's just a guess my boys skulls was rounded like that
