Fire your doctor and get a new one, immediately! It is not normal to have discharge for three months. I had nonstop discharge for three months, too, and as it turned out, the doctor badly botched the LEEP but didn't bother to tell me.
In addition, get copies of all your lab reports so that you know exactly what has been happening, all along. Check to see if there was dysplasia in the endocervical canal and the endocervical glands. That will tell you if your doctor even chose the correct surgical option.
Also get a copy of the doctor's notes from the surgery. This way, you'll know what happened.
But definitely get a new doctor, and get a referral to a GYN/ONC, today. This is not to scare you, but you'll be getting an expert opinion about all of this, which could put your mind at ease, or get you actively involved in what is best for you. Whatever you do, please make sure your decision is informed.
