Boy or girl?

This is what the tech gave me. I'm 16w4 days. 
 aid it's a boy, didn't say how sure she was. It's blurry and I'm not even sure if it's a potty shot. All I see is 2 white lines and maybe a leg. I had my ultrasound at a elective ultrasound studio. I just wanna be sure before I go buy stuff.
