Hi ladies, I too have my 20 week scan at 2pm tomorrow and am petrified so its good to hear I'm not the only one! Winngrin do you know what you're having? We haven't found out yet and I'm so scared that I'll see something I'm not ready to see on the screen as I've studied so many ultrasound pictures I know what to look for now, argh! Still unsure whether to just find out tomorrow or not really...?
