Abnormal PAP smear while preggo?

So my doctor just called me, CALLED, which freaked me out to begin with. She told me the results of my Pap smear came back with abnormal cells.  She said it doesn't LOOK like cancer, whatever the hell that means, and she wants to do a biopsy. How worried should I be about my little peanut? Or about myself??? I'm 11 weeks pregnant and losing my shit right about now...
