RESULTS FROM PUNCH BIOPSY - confused?

Hi everyone back in novemebr had my letter 1st smear said hpv positive borderline changes. 32st December had punch biopsy where consultant said abnormal cells looked deeper and could maybe be cin 2 but biopsy will confirm.

25th Jan got my results saying biopsy taken was negative (normal) but need another smear in a year??

I’m just confused as to why consultant though/said that but turns out to be negative can anyone shed some light or had similar experience?

Also I have had my first person 25th Jan and after 9 days looked like it was coming to end and now I’m still bleeding slightly?
