Many women have abnormal pap smears on occasion. The doctor then does what's called a "cone biopsy"...this can turn up totally negative, pre-cancerous, or cancerous. Two things to keep in mind: As someone said in an earlier reply, it's really likely that the recent birth caused some changes which, when tested, will prove to be absolutely nothing. Second, while no one wants to have cancer, cervical cancer is one of the most easily cured types. Oh, there's a third!: your age! It's highly unlikely you have cervical cancer at 16.
So, once you get the results, post back and let us know...we'll all be praying for you and thinking good thoughts.
