What part is the nub?? (13w3d)

Hi everyone,
At the risk of looking neurotic, can anybody have a look at the close up pics of my babies scan. After saying I wouldn't be obsessed with studying the scan pics...... I have!

I just cannot see what part the nub may be, it was not a clear scan as babies leg was in the way. I have numbered the 3 areas I thought may be a nub.

Thank you for anybody who takes a second look for me! ☺

Thank you!

For a while I was wondering it was a 3 nubbed baby lol!

It's difficult to decide what is going on with that nub! One pic looks like it has a stacked bump on top (boyish) the other pic maybe looks straight (girly)x
