First, relax, you DO NOT have cervical cancer.
Did your doctor test you for HPV? Did you ask? You can call and ask if it would make you feel better.
ASCUS is, as you may know, is MILDLY abnormal cells. ASCUS stands for Atypical Cells of Undetermined Significance. It could be caused from cervical irritation or possibly a slight infection. This all means, it isn't something you should be terribly worried about. Go back in 6 months and get a repeat pap smear.
This does not mean you are infertile. This does not mean you have cancer. This does not mean you have HPV. It means you have mildly abnormal cells on your cervix.
