I spoke to my gp yesterday who didn't have a clue about who funds what but gave me the names of 2 other hospitals I could have been referred to. I called Kingston and spoke to a very helpful fertility nurse. They wouldn't charge for clomid or the scans and she was quite shocked to hear how much Chelsea & Westminster were charging!
So she said I could ask my gp to refer me to Kingston but it would inevitably involve a bit of delay in things as I'd have to be seen first by their doctor/consultant for him to agree clomid is the correct course of action. She said hopefully we could skip nearly all of the other stages I've gone through with C&W (seeing the nurse, tests, hsg, etc etc). So I've asked my gp to write the referral and we'll see how far away the appointment is. If it's going to be months and months I might still just suck it up and pay at C&W but if it's not so long then I'll switch.
So annoying to be doing all this chasing around! Why can't there just be one policy for the whole of the nhs???
