Im currently on a waiting list atm the have the LEEP done as i have CIN3. I asked him how long id have to wait after the proceedure to TTC. Im not pregnant but what the OB has told me is that it takes years and years for the cells to develope into cancer. He said if afterwards i do fall pregnant and they find the cells, then there is plenty of time for them to treat it after youve had bubs. They dont treat it or remove the cells while you are pregnant as it will thin your cervix and may least to complications.

So if it comes up with high grade, they will just wait until youve had bubs and then treat it.
