Is this a nub?

I've been looking through the video from the ultrasound trying to figure out what is a nub. Is this one? I know the nub theory doesn't work when teh baby is upside down, but I'm still wondering if this could be a nub. Thank you.

I don't think so?? if you could post the whole ultrasound on youtube then we could guess of off that for you :agree:

I don't see a nub, sorry.
