Skull/Nub gueses 13w1d

I don't think I see a nub but I might be missing it. If not, can anyone make a guess based on the skull at 13w1d?Attachment 7576

Total guess cause I cant see a nub at all
Id guess girl :)

I think I may see part of a nub... Guessing boy!

I'm guessing boy but I'm not very experienced with guessing..lol

Not sure I see a nub at all...

girl from skull

No clues.

Thanks for the guesses! I didn't think there was a visible nub and a skull guess is difficult with the hand next to the face. Guess this baby doesn't want me to know yet! Lol

Any other guesses?
