Birth control appointment

I'm going to talk to my doctor tomorrow about getting birth control pills to regulate periods and as an extra form of birth control, and curious as to what the process is.  Will he need to do a pelvic exam? I am sexually active but under the age of 21, which is when he recommended that women start getting Pap smears done. I'm not nervous because I understand he is a doctor, just curious if it was necessary or not.
