Gender Confusion- 19 Weeks

I went to a clinic for this, so the lady wouldn't tell me the gender. She said I could take pictures, but the quality of their machine was just awful. The first picture looks like the umbilical cord maybe and the 2nd looks like boy parts. A few minutes after doing the potty shots, the girl doing the ultrasound said, "she sure is moving a lot." That was just once, though. She called baby "it" the rest of the time. Sooo is it a boy or girl? I have my actual anatomy scan on May 8th.
