Private or NHS did anyone experience getting the wrong gender prediction from the sonographers?

So not me but I always thought this would happen to me and it’s more common than you think! My GP said it happened to her, told she was having a girl but had a little boy.

I asked for confirmation to the 2nd sonographer that I saw and they said the same gender as 1st one so now I'm convinced enough ;)

I had hyperemesis when I was pregnant with my son, I had so many scans during my pregnancy due to being sick almost everyday till the day I gave birth. I was told my son was a girl🤦🏽‍♀️🤦🏽‍♀️
