Question for UK mommies!

At what week did you have your first scan? 12th or 13th?? I'm 11 weeks today and my bump is getting harder to hide but don't want to tell people until I've had my scan confirming everything's okay! I had my first appointment with my midwife on week 9, but my scan appointment hasn't come through yet? I'm desperate for this scan it will stop me worrying and wondering if everything's okay and make life easier for me without having to constantly hide my bump!
