What is a nub?

[RachKH]

Could someone please help me locate the nub? I've got a good profile picture of my baby at 12w and 3 days. Am I looking for the angle of the really prodominant white line (down near the legs) or something below or above that. My baby's image has a really pronounced white line (long) hear the leg, but then a line below that, then the spin lower. If anyone could help that would be great Thanks.

I'm wondering this too! Hope someone can get back to us.
