Can do preg. test: A woman on birth control pills, taking them properly, and beyond her first pack of pills... has no fertile day and has no fertile week. She is not fertile when on birth control pills. That means she has protection against pregnancy every day, regardless of where she is in her pill pack. Commonly used antibiotics such as minocycline don't change the effectiveness of birth control pills.
