If : If you have started your birth control pills as directed, meaning you started either on the first day or the sunday after the beginning of your period, then birth control pills will be effective after 7 days. You will need to use a back up method if you did not start the birth control pill in alignment with your menstral cycle. This is also true for birth control shots and patches. The reason being, you may have ovulated (released an egg) after your period, making pregancy very likely if you have unprotected sex.
