A few months ago I had treatment for CIN2, I'm supposed to have a follow up smear test. However, I've recently found out I'm in the early stages of pregnancy. I want my be able to have the smear until 3 months after baby is born. If CIN has returned how far advanced could it get in this time? I'm scared I'll be allowing CIN3 or even cancer to develop and it's ruining my pregnancy.
