Pap Smear... How to consult a parent about it?

Anonymous
Generally, girls are supposed to have their first pap test between the ages of 13 and 15. I've never had mine and i'm almost 18.
In case you didn't know, a pap test, or pap smear is a screening for cervical cancer and a checkup on a female's cervix.
The doctor inserts a thingamabob into the female's junk and the takes a sample and sends it into the lap for screening.
How do you think I should inform my mother that I'm ready for this test?
Should I just tell her, should I work up to it? How would I phrase it?
Like I said, the test should have been done years ago, and for it to be free, I need it to be done in the next 10-11 months.
I'm rather embarrassed about bringing this up.
