My very first papsmear (was naughty didn't have till I was 23) I had CIN 3 I had colposcopy and biospsy done and they decided to do 3 monthly colpsocopys for a year then went to 6 monthly for a year then yearly for 2 years then too every 2nd year.
They did talk of laser but decided to wait and it did resolve it self, it has been 10 years now and all been fine ever since.

Good luck hope all ok xoox
