can't remember my last smear results

So im going for the colospoly in the morning high grade cells. I had a smear in 2011 I can’t for the life of me remember getting the results
.
They was some confusion with my contact details in the past Im scared I might of got abnormal results and not know about it. I registered for a new doc recently and got a smear invite in the post. Would it of been on my letter if I was meant to go before?
