If i am on the depo-provera shot and i want to switch over to the pill can i do it now or should i wait untill my three months are up what's the best way?

Depo to Pills: It's best to time the conversion from Depo Provera (medroxyprogesterone) to biirth control pills in such a way that you remain protected from pregnancy. Since Depo-Provera expires at approximately 3 months, coordinate an overlap of getting your pills started the week prior to expiration. That will allow you to remain protected during the transition.
