I remember arguing with a sonographer about dates, saying I'm def 'x' she said well by the leg length measurement I think they do, you're def 'y' I was confused how I'd nearly lost a week.
Then with PFB they managed to mix something up and I got an extra scan as they had me down as 16wks when only past 12. Got a free piccie for the stress too.
The thing I hated about EPAU was how they'd say oh you again, like it was my favourite place to be. I'd be there praying everything was ok when it seldom was. Even the sonographer made a sharp comment once, she meant well but it didn't come across like that.
