20 week scan... Original scan was WRONG

I went to a friend of my husband's to get an early gender ultrasound at both 15 weeks and 19 weeks... She's just kinda learning and both times she said it was a boy. 
Well, today I went to a professional ultrasound facility for my anatomy scan and to our surprise, it was an obvious girl!!!! We are so shocked!! 
I'll post pictures below. First picture is my 19 week scan and the second is 20 weeks...
