12w 2d ultrasound - boy or girl??

 Hi All, I just stumbled across this wonderful site! I was hoping somebody would like to take a guess (educated or not) on what my little bubba is? I have had a feeling of boy, just due to old wives tales like no morning sickness and savoury taste etc. but lately the thought of girl has crossed my mind. Im not sure that what I think the nub is in this picture IS the nub lol but hopefully...
