Is there a nub? Can anyone guess gender for us?

For some reason my computer will not let me upload. Here is the link, baby was being a little stinker and was hanging out upside down and moving around constantly :), so this is the best shot we got. Would love to know any guesses on gender that you might have and greatly appreciate you taking the time to look!

Please please take a guess for us!

Sorry. I'm not seeing a nub in either of the pics

Any skull guesses? I know that's not super accurate either... Just stretching here :)
