The Gardisil won't cure the HPV you already have it just protects you from the others (BUT Gardisil only protects against the 4 most common types of HPV). Did your doc tell you if it was mild dysplasia? Moderate? Severe? The biopsy/colposcopy (never can remember how to spell that word, it may be right?) consists of the doctor pinching a small amount of tissue from your cervix where the abnormal cells are. It does sting a little and feels like menstrual cramps while it's being done, which fortunately only takes not even 5 minutes.
Now, if you have mild dysplasia (pre-cancerous cells) it does NOT mean you have cancer. It could turn into cancer if you completely let yourself go; i.e., not eating healthy, getting a little exercise, not stressing out, etc. With mild dysplasia, you need to keep up with regular check-ups just to keep a watch on it. Below is a good website about dysplasia:

You can have children with cervical dysplasia, although it may act up during the pregnancy. I found this though about pregnancy and cervical CANCER:
"It is unfortunate that a woman cannot get pregnant after treatment for most stages of cervical cancer."

It's all hard to understand and figure out all the confusing information at first, but you'll get it. If you have any questions, comments, need to vent or anything, just come on by. Good luck to ya. :)
