Advice on smear test age

Is there anyone that could give me advice on what age smear test stops exactly, I had my last smear test on September 2012, I am 64 now and my next birthday is in October would anyone know if I will receive another smear test letter before October, because I am a bit confused when they say that smear tests stop at 64 but does this mean that you might still get an invitation before you are 65
