Is this really a boy? Opinions please!

I posted this question to a Facebook group I'm a part of but wanted to get some more opinions: 
So the hubs and I were talking the other night and I was telling him how our little boy's potty shots looked different from the ones I've seen you all post. I know our ultrasound tech was having difficulty getting our modest child to cooperate and she did say his cord was hanging down so she kept going back to make sure it wasn't his cord. Just thought Id get ya'lls opinion. The first pic really looks like a girl to me and the other two it's hard to determine if the winky dink is attached. Thoughts?
