I had the same thing happen to me hun, had my Pre Op back in January and just over a week to go (op 3rd April) they tell me the results are only valid for 6 weeks and that I need them redoing!! Of course I flew into a panic thinking I’d have to move my op date be ause the results wouldn’t be back in time but my pc was brilliant and arranged and looked after everything.. They only take a few days.. You’ll be just fine.. Chat with your pc she’ll sort it for you.. But don’t worry I’m sure it’ll all be ok..
