HELP! Keen eyes needed! Idk where to look! 13w1d

[Verity]

Can anyone shed any light? Is there a nub pictured in this or is the leg in the way? I'm also not sure where to look or what I'm looking at haha and I haven't had any luck posting in other forums or Facebook pages! I've been told there isn't a clear nub but I still don't know where it is or if they mean they can't see it at all. Any and all guesses/opinions welcomed! This is from my 13w1d scan.THANK YOU!

*UPDATE* I was told the red circle is the cord by someone in another group that used to gender ID before studying nub theory. She did not guess, however. So, idk.

The thing in the green circle looks like the umbilical cord. The one in red appears to be the nub which looks girly to me.

Maybe girl

Thanks! I've been told girl and that the red circle is the cord, idk what to think

[Verity]

Bump, any insight?

I've read the cord doesn't show up as white on a U.S. I'm not sure what that is but I was told the red circle is too long to be anything be the cord
This is from our 12w2d scan if that helps! Any thoughts?

Am I crazy? Did I just make something out of nothing? Lol, cuz I really don't know
