Is nub visible? Boy or girl?

I had this ultrasound at 11 weeks 6 days, but baby measured 12w4d. Not sure if that is nub or embilicle cord. Any ideas? Thank you ahead of timeAttachment 7696Attachment 7697Attachment 7698Attachment 7700

I'm sorry- the pics are too small. When I try to zoom in- they are really blurry.

Ok, Ty.... I uploaded from cell phone I'll try to get a better one :)

Ok ty! I was thinking boy. Looks like its sticking up to me but I'm not very good at this :)

Its flat, looks girly to me

i can't tell. i was gonna guess boy, though, but pure guess with these pictures.
