13w 1d is that a nub to judge angle of?!

This scan was on 2/17. According to my cycle, the baby is 12w3d. According to a previous dating scan- I am 13w1d during this scan.

Any and all predictions are welcome. The more the merrier!

Pretty please with sugar on top!

Not sure if what I'm looking at is a nub. Could be part of a leg. If it is a nub, I'd guess girl.

Someone told me that this is the nub. With the arrow pointing to it. Is that kinda long for nub? I guessed part of leg as well.
Any thoughts?

I'll admit freely that I'm not a sonographer, so it could be the nub, I just don't know. Any other nub-type scans?

yes, if that is the nub my guess is girl as well
