Is it a boy?!

St

Went for my 12 week NT scan today. Baby wasn’t cooperating so the tech was looking at other things. She gave us this pic of the legs. Right after she printed this she asked if we were going to find out gender. I told her we will at 16 weeks. Do you think she could tell? I mean, this looks like a penis to me, but is it to early to be sure? Sooo confused! I did not want to find out because we are having a gender reveal party after our 16 week US. But that really looks like a boy to me! Is it???
