Ultrasound disaster! Please help me!

We went to a private 3D/4D ultrasound place to see the little babe and find out gender. They do them starting at 14 weeks but decided to do 15 instead because that's when I found out with my other two kids. I was very disappointed at this new place I went to and actually left crying. Baby had his/her legs crossed (I know that's not the tech's fault) and was being stubborn. But instead of asking me to come back for a rescan she just said "well I think it's a girl" and then just wrote it on a photo. The only photo I have is a side view and it doesn't even show the legs. Can anyone help me decide what the heck is going on and tell me boy or girl. I am very familiar with both genders as I already have one of each. This definitely seems boy to me. Help! Thank you in advance!
