Have you ever had abnormal cells after a pap?

I am being called back for a follow up with mine and the nurse said she couldn't find my chart but abnormal cells are common. Before I go again tonight could any tell me if they have had this? What was the treatment? How serious was/is it? Did it go away? How long ago did you have that and have they come back or changed?

Any info or experiences would help!

Thanks so much.
