Skull or nub theory? Can you tell?

[luvgabs]

I had my NT scan yesterday and measured 13wks. Two techs in the room kept calling baby a boy and now I'm really curious. I didn't ask what they thought because I thought it was way too early to guess. When they did a potty shot I thought I saw something between the legs, but also thought it could be part cord. Any guesses here? I know the pics aren't the best.

There may be the faintest hint of a boy nub in the first image but I'm not certain so wouldn't really be surprised either way.

Wow! A lot of boy guesses! Are you all looking more at skull? I can't tell where a nub is. This is really exciting!

Any help on seeing the nub?

Thanks, do you think the lighter line coming from the black circle is the nub? I'm having trouble seeing it.
