Baby girl????

Hey ladies just had an us done at 16w 1d and baby was not cooperating at all!! Our little peanut was refusing to move their little legs out of the way. Finally the tech was able to snap this pic and is pretty sure we are having a girl!! Won't have our final confirmation till the anatomy scan in 4 weeks. I don't see a little peen but I don't see distinct 3 lines either... What do you think our baby gender is???
