What if you dont want to have a pelvic exam can you still get the birth control to regulate your period?

Maybe: It depends on the setting. If you are sexually active and thus at risk of sexually transmitted diseases, it is not ethical to prescribe pills without a full evaluation. If you are not, there are ways to gather basic information without a pelvic exam that are reasonable. This is something you can ask the office crew or doctors nurse before you schedule an evaluation.
