Josie I'm so sorry to read your news. However, two follicles at 10cm each could go on to produce two eggs. I know things are developing slowly for you, but it's not impossible with a bit of patience. They are still developing.
I'd back what the others have said on here, though. I don't know the ins and outs, but I do wonder if you'd do much better on the short protocol. Even if not, if you did turn out to be a suitable candidate, it's certainly worth a shot.
Do you mind me asking the reason for your infertility?
To explain NHS funding, your funder (currently the PCT) will have a service level agreement (SLA), which is a contract, with one or more ART provider. These could include an NHS managed centre (which also treats self-funded patients) or a private clinic that is contracted to provide the service to the NHS. You are normally automatically referred to the clinic with which your PCT contracts, although it shouldn't be impossible to switch. The best thing would be to discuss it with your new clinic. They may know how to go about claiming the funding and so it's worth asking the question if you begin contacting other clinics for a second opinion.
Be wary when considering the clinic success rates stated on the HFEA website (really sorry to disagree with you here Karbea, just playing Devil's advocate), BUT some clinics fiddle their results by turning down difficult patients, which other clinics will persevere with to the detriment of their position on the "league" tables. The HFEA data is useful in identifying the outliers, but any clinic performing close to the national average is probably absolutely fine. Clinics trying and pioneering new treatments probably won't have the best success rates as de facto, they'll attract patients with multiple IVF failures wishing to try something new.
Wishing you best of luck!
