Please help--Can't find nub!

Hi ladies,

I feel like my baby is at a weird angle here and I can't find the nub! Can anyone see it? Do you have any guesses? Thank you!!

I can't see one either sorry

I'm going to guess girl.

I don't see the nub.

The only thing I can think is that this could be the nub (the 2 white lines that I circled). I have seen a few nubs that looked like that. I was supposed to be 12 w 6 days but they said I was measuring about 6 days ahead so I guess if baby was closer to 13 w 5 days, maybe if it was a girl the nub could be becoming internal already? I don't know! Thank you all for your guesses!

Maybe girl.

It's not as clear as I like but I guess girl
