Abnormal Pap smear

Sharlene

Is it normal to sometimes have an abnormal Pap smear? I had one last year and had to get a colposcopy done. It happened again this year, and I have to get a colposcopy done again. Last year she saw some white patches on my cervix, is that something I need to really worry about or does it happen to other women? Before all this my first Pap smear was normal.
