Doctor being vague. Cervical cancer, or not?

A pap smear I had done in March turned out abnormal so a colposcopy was done. The doctor took two biopsies. At that appointment I was able to get a glimpse of my file and I read something about my cells reaching a "high grade", or something like that. After the biopsies were looked at, I received a call back (a couple weeks ago) saying that the biopsy taken inside my cervix came back normal, but the biopsy taken on the outside looked suspicious. She told me that since I'm young, my age is on my side so they're going to wait 6 months and take another biopsy to see if it may clear up on it's own. I'm 20 years old and active duty military so I've been going through military hospitals. I know their training is not to the extent of a public doctor so I'm not sure if I should take their word on waiting. I've heard a lot of survival cases are due to early detection and waiting 6 months to see if it clears up on it own just doesn't sit right with me. I want to know what it sounds like I have. I'm going to call her back on Monday, but in the mean time I can't stop speculating.
