guess on the sex?

I was cleaning and came across my sons old sonogram from when he was 20 weeks. That's when we found out he was a he haha. This baby we are deciding not to know the sex....... that's not to say I'm not curious haha. But I haven't posted anything about guessing my baby's sex yet because I was really wanting it to be a surprise. That being said when I came across the picture I noticed a very obvious difference..... the direction they are facing. Now I have no idea if that can say what the sex is (I would assume it really doesn't effect it but I don't know haha). So anyway, with June baby in the first picture and baby boy born January 2013 in the second, what would your guess be? I'm taking a break from cleaning the house so I'm happy :)
