Any guesses just for fun!

[Anothernub]

Hello!
Pregnant for the second time & just for abit of fun wondered if anyone has any suggestions on sex based on my scan? I have no idea what I am looking for with the ‘nub’ theory! I don’t even know if the ‘nub’ is visible!
thanks in advance : )

Not the best pic, but I’d say girl.

Thanks for replying! Is the nub actually visible?! I’ve tried to work it out for so long 😂
