Nub or leg?

[sbined]

I was looking through the 12 week ultrasound again, and came up to one confusing picture.
I posted my baby's nub about a week ago, and got mostly boy leanings from various sources
(I also think it's more of a boy nub).

Anyway, this picture (the one with the whole fetus shot) shows a nub or leg, can't really tell, but it looks so different from the 8 other nub shots that are basically identical.



It sticks straight up like a classic boy nub, and it seems as thick as the umbilical cord. Not sure if it's a nub or a leg for that reason.

Since the picture in question is obviously a boy nub, it doesn't change the verdict.
But I was just curious if one nub can look so radically different from other nubs during the same ultrasound screening or if it's indeed part of a leg.

Oh, in the picture in question, I think the baby was upside down. Maybe that could be a factor?

Anyone with an opinion or a similar experience?

Can you post the video?

Sorry, no video. I only received the screenshots of the ultrasound via CD-ROM
