You and your doctor can decide when it's time for you to begin Pap testing and how often you should have the test. In general, doctors recommend beginning Pap testing at age 21.
Women should have a Pap smear in the middle of their monthly cycle, or about 10-20 days after the LMP (last menstrual period) began. At least 2 days before the test, women should avoid having anything in the vagina including sexual intercourse, douching, vaginal creams/suppositories, or spermicide.
