nub theory/skull theory guess

Hello, is there a nub in any of these photos? Is it the bright white line or shadow on the leg?
Based on nub or skull theory would you say baby looks boy or girl? (13 weeks & 1 day) Sorry photos aren't the best quality, baby was camera shy to begin with.
Thanks.

Yes sorry these just aren't the quality I prefer for guessing. the nub is the white line in the top pic but the baby is in an odd position so it could make a flat nub look angled and it's not a reliable shot.

Gorgeous baby though!
