Why is your pap smear abnormal if you have no cervix?

It is impossible for a pap smear to be abnormal if you have no cervix. A pap smear is a test used to detect abnormal cells in the cervix, which is the opening to the uterus. If you have had a hysterectomy, which is the surgical removal of the uterus and cervix, then you will no longer have a cervix and cannot get a pap smear.
