Help! Is it really a girl?!

We had our Ultrasound yesterday and baby wouldn't open its legs very much. It took the tech about 20 minutes to finally get this shot...she seemed fairly certain she saw the labia (on the right side of the picture) but I'm just nervous she didn't get the right angle & could have possibly missed some boy parts! What do you think?! You can see the "3 lines" but should we count on it?!
