UK mummies, advice?

Clare
Hello to any UK mummies! I'm wondering if any of you have managed to get an early ultrasound (at maybe 8 weeks) just because you were worried? I don't really have any cause to worry, apart from being paranoid and having a bad feeling that somethings gone wrong, but would love some reassurance before we announce to family. If you did, how did you get one? Who would I contact? I've had one GP appointment but no contact from midwives yet. Thank you!
