It's recommended that you see your gynecologist once a year to get a pap smear after you turn 18 or after you become sexually active. You may see your gynecologist more often if you have experienced medical problems in the past.
Females should start to see their gynecologist every year once they reach the age of 18 or become sexually active. It is important to get your yearly checkups to ensure you have not developed an infection.
Once you are eighteen or sexually active, you should get a gynecology check-up at least once a year. If something happens in between, i. e. trama to your reproductive organs, then you should go more often.
