Hello, this is a similar reply I posted to another thread.....
I have tired to get a dating scan on the NHS and was told that my first scan would be when I'm 15 weeks! This feels like an age away so I did a bit of research on the net and found a private clinic in Canary Wharf (they are called My Ultra Baby and also have clinincs in West & North London and Hertfordshire) that offers scans along side your NHS scans from 5 weeks.
I am going on Sat when I will be 9+2 (I think) so hope to hear the heartbeat and get a fairly good look at the little one, even if it's just a blob. Perhaps that's worth a try? It is a bit expensive (£75) but I reasoned that it was worth it to stop me going crazy, plus you don't need a referral from the GP. Hope this helps.....
