Have you been looking at the lab reports, all along? If your entire cervix is truly diseased, as the doctor said, why were you not sent to a GYN/ONC? And why did the doctor not do a cold knife cone biopsy? Was it in the endocervical glands? I truly hope the results are good. But it sounds like you might want to consider getting a different doctor for your follow-up healthcare, from here on out. If it really is that bad, insist on seeing a GYN/ONC.
If your cervix is that bad, you may qualify for a trachelectomy. It removes the cervix but leaves the uterus intact for fertility purposes. Here are some links.

I hope this helps you get started in gathering information! Again, please look at all of the lab reports. That will be your first step in deciding what is best for your condition and your body.
