I a smear 7 weeks ago then had to have a lletz procedure. Got a letter today saying I have to go back for another smear in 6 months, but i am cancer free, and have hpv test. Now I have zero knowledge of the hpv virus. Is it an std? Does your smear test for that? Last smear I had was 3 years ago, if I get hpv positive result does that mean that I've gone from hpv negative to hpv positive?
