Sorry SuzyChick,
I don't know the answer to this one, the only thing I can suggest is to drop the QE an email. I don't have their address at hand but you'll find it on the HFEA website if you click on the 'find a clinic' option.
I hope your NHS wait at the CfL isn't too long, they do ask you when you want to start treatment so if you do squeeze a cycle in at the QE you'll be able to defer the CfL cycle for a couple of months if it comes earlier than expected - and of course if you need to!!
Good luck in whatever you choose, or are allowed, to do.
Also good luck to Hollysox, I hope it goes well for you.
Andrea
