Ultrasound anxiety

Rene
So, where I live there is an ultrasound place where they are trained to be able to tell the gender as early as 14 weeks. I went when I was 14 weeks 3 days. She looked at 3 different angles and determined I was having a little girl. Well, i have seen all these post about techs telling them the wrong gender and now Im nervous it could happen to me. The lady has been doing this since 2007 and said she has never been wrong. Here is my ultrasound pic, do you think this could change at all? I go Friday for my anatomy scan at my actual obgyn, but a little reassurance would be nice!
