It depends what you had done. If just a leep, and you have clear margins, 6 months is ok (if you stress though why not just go in at 3 and 6 months - its just a pap
I for example had part laser, so I need the dr to check those areas via colpo, as I couldnt get samples in that location --- so I need a checkup at 3 months.
I am going in every 4 months for paps from now on. Its no big deal - many places offer free paps too (clinics etc) so i figure , why not ?
