Is it a boy??

After our 12 week ultrasound, the doctor said it is too early to tell the gender, which is what I expected. But hubby swears he sees boy parts in a few shots. The more I look, the more I can see what he means, but if a doctor said it's too soon, it's not possible... Right?? 
I've wanted a whole family of boys my whole life and I know hubby wouldn't mind a son, so are we just getting our hopes up or is that something down between the legs? I know, waiting to confirm at 20 weeks is the thing to do but really- like I'm not going to think about it? lol
