How exciting to be having your 19wk scan!! I was so totally excited when mine finally rolled round (at 21wks) that I couldn't wait to get there.... of course little miss wouldn't show us what sex she was - even after turning every which way and having a walk around!

I would say you should ask for the photos if you want them - I always got them without a film - maybe it's changed now? I would ask anyway and see if you can get them

Good luck - I hope you have a great time!!!
