Good luck with your scan!

With my first pregnancy my first ultrasound at 9 weeks was transvaginal as they couldn't get a clear pic from the outside, but I was a lot heavier than with this pregnancy. All my US this pregnancy have been external....

It's not a huge pole either!! It's actually not that bad, and it's ummm easier if you just ask them if you can put it in yourself - but you may not need to so don't stress to much
