That def looks like a boy. I can see the umbilical cord too and that is def a penis sitting out the middle of the testes and the cord is running beside it. I'd be VERY suprised if you have a girl. My 14wk u/s looks very similar to ur one and I was given a 85% chance at that stage (get confirmation this thurs so will let u know) of a boy. The fact the legs are wide apart is also a good indication. Girls like to cross their legs, boys don't cause it squishes their boy bits heheh
