NuvaRing is not readily available in the UK (yet), though it must be increasing in popularity very slowly, as I saw an ad for it in my (UK) Glamour magazine this month! You may get luckily if you visit a busier, more progressive family planning clinic, but it will be totally dependent on whether your GP or clinic has heard of it/has access. I used to use the NuvaRing in the US, but used Implanon (quite similar, except it's permanently implanted in your upper arm for 3 yrs) when I moved here.
