I don't know why I do this to myself, but I posted the pictures on a different website and one person said she thought baby was a girl. She said both genders have a nub at this stage (clearly, she didn't look at my nub pictures), and that the potty shot she would expect it to look bigger and more like an actual penis?!?! I'm so insulted, LOL! I actually thought this potty shot was pretty impressive for 13 weeks, and Daddy and tech certainly seemed impressed:) I know potty shots aren't terribly reliable at 13 weeks, but is there really any way that could be swollen girl bits?
