Anyone told wrong gender at scan?

Claire • 1 little girl 8 and no.2 on the way
I'm 26 weeks with baby girl which I'm happy with, found out at 19 weeks then again at 21 week scan both sonographers thought girl, but I've had so many people say "oh I still think your gonna have a boy or I think it's a boy!"😕 I've bought so much pink stuff already I'm starting to worry! 
Anyone else been told wrong gender at scan before??
