London it is very easy to get a scan if you are willing to pay. What you need to search for is 'endometrial ultrasound'. There is a place called sonoworld near Regent's Park I've been too which was good but I don't think there is much between place except price. I had this done recently and if they can't see things through the abdomen they will then do a transvaginal ultrasound which although undignified was completely painless, quick and very reassuring.
