Ultrasound wrong


When I was 14 weeks pregnant my husband and I paid somewhere to find out the gender. We were told it was a girl she didn’t show us between the legs just a side profile saying one line means girl. She would not show us a potty shot. Well now I am 20 weeks and had a ultrasound done from my doctor. This ultrasound technician said it’s a little boy. We asked him if he was sure that we were told it is a girl. So he showed us between the legs there it was clear as day a penis. Has this ever happened to anyone else?
