Wohoo!!
I decided that after almost 8 days waiting it was best to phone the lovely people at the CAA medical center. They advised me that my certificate had been posted out the following day but must have been 'lost' in the post...
Phew, at least there's nothing to worry about and best of all I passed!!
So pleased! Although what on earth has happened to the royal mail? Lots of things being mysteriously 'lost' in the post at the moment.... but that's another thread on another borad I guess!
Cheers
