I can't tell on your scan image. I've heard it's a very inexact science before 18 weeks, though. I don't see a penis, but I also don't see a clit & labia, because it's not at the right angle to see the details. Girl maybe?
I'm only 7 weeks, so it'll be a while before I find out yet! I've got a dating scan coming up, but it'll probably still be too soon. Based purely on symptoms & wive's tales, I'm guessing boy for myself. I don't put much stock in wive's tales, but I gotta base my guess on something this early, right? lol
