Please help me figure out where the nub is! 13w1d

[kneeswrites]

At my first OB appointment I got these for pictures, I've been obsessively studying them and I can't find the nub because I can't figure out what kind of angle the baby is laying at or where the legs are. There's like four places I think might be the nub but I'm not sure which one it is even though I'm almost positive his picture definitely has it. It's very clear I just can't figure out which one is it therefore I can't even analyze it!

When I posted it here and initially thought I knew where the nub was, I thought it was all girl and everyone agreed, but on another page on Facebook everyone said boy. I was just wondering if yall could look at the outlined edit I did and then the original and see if you can help me figure out where the freaking nub is! It's driving me crazy!

Oh and I included a third pic where I think I see the genitalia, maybe a boy??

I don't see a nub at all, but would guess boy as well

Honestly, I really can't tell but I think its a boy.
