Looks like a girl! The accuracy is really high in studies of 'nubs' (more like 90+%; they do a lot more than look at angle in a still shot - they map out the nub on different dimensions to find the midpoint). I saw a conference presentation suggesting that in 'real' settings, nub guessing is less accurate but still really good. It gets more accurate at 13/14 weeks though, so yours is early.
