I too have had a LEEP for cin II and it might have been III as well, I can't remember at this moment. They were able to remove it all and the recovery wasn't too bad. The recommendation that i got was to wait 3 months to TTC again, but I have seen stories of ladies conceiving within those three months that had a successful pregnancy. It was probably 2 or 3 weeks before I could have sex. The procedure itself is fairly quick.
I am still dealing with having a pap every 6 months, with an occasional colpo as well. So far nothing has progressed beyond just watching it closely.
Please feel free to PM me if you have any questions or need anything. I know it's scary, but please try not to worry too much!
Again, I'm so sorry and (((huge hugs)))
