Hi Soul,
I had my 20wk scan done today and it was awesome the lady was fantastic and it took about 45 minutes.She checked everything and explained what she was doing the whole time.She asked if we wanted to know the sex but every other time I have had a scan they have never asked me if I wanted to know or not.

I got a 3D video of the scan and that is just unbelievable.

Don't be afraid to ask anything, they are there to work for you and you are entitled to know anything you want to know about your baby.
All the best for your scan and I can't wait to hear how it went.

Take care
Michelle
