Looks girly!

I would guess girl but baby is upside down and the nub angle can change over the next couple of weeks so I wouldn't get yoru hopes up or down based on all the guesses.  Congrats on your baby!

Thanks for all your guesses. Though the baby in the first pic is actually right side up. In this pic the baby is presumed upside down. Is the nub theory void if the baby is upside down? And if so why?

Even in the second picture it still looks pretty girly.  Baby is upside down in the first pic you posted though--you can tell that if you look at the direction that the sides of the picture are going (the way the ultrasound bounces off.)  I would guess that the tech may have flipped the pic for you.
