C1nders so sorry to hear your u/sound wasn't a great experience. I'd be making a formal complaint like Cailin suggested

My 12 week ultrasound was a bit like that - not able to lie in a position that I could see any of the scan - in the last minute she said see, legs, arms, head heartbeat and then I left with no pictures. It was my second child but I still left angry and upset - so glad I'm getting to go to a different clinic for the next one. My only relief was she was able to confirm everything seemed ok.

Being the 20 week I can only imagine it was worse. Ask your doctor for some pictures they usually have plenty of spares especially at the 20 week - I was able to get hold of the films (ike xray films) from my 12 week so that was at least something -not great for putting on the fridge though. I'd also be letting your Dr know as these places depend on referrals - maybe your doc won't refer further people there if he has a different option (they usually have 2 or 3 different places they send people).

I'm sure your doctor will confirm everything is fine and have a lot better bedside manner and some understanding. Good luck
