Progesterone controls release of eggs
Prometrium will not make the birth control pill less effective, but I can't imagine why you would take a birth control with progestin as well as a progesterone pill. Please make sure all of your prescribers are aware of all of the medication you're taking.

Both are safe and effective to use to regulate your period. There are many types of birth control pills and some only contain progesterone (POP's) and some are combinations of progesterone and estrogen. Progesterone only pills are still birth control pills. Birth control pills, containing progesterone only or a combination of progesterone and estrogen will regulate your period and protect your from pregnancy! However, you must take your pills everyday and at the same time, otherwise your period will not regulate and you will put your risk of becoming pregnant. For further information on which type of pill is right for you, you must visit a physician (example; Planed Parenthood), and they will choose which method is right for you.
