[|Human|] My doctor switched me directly from the pill to the depo provera. I never got off of the pill; I took it the morning I got the shot. I was wondering, how long will it take for me to be protected from pregnancy? Am I already covered because I switched straight to another birth control?
[|AI|]  Hello, Thanks for sharing your health concern with us. Depo-Provera starts working within 24 hours if taken during the first five days of the menstrual cycle. As you were regular with the oral contraceptive pill, protection should be complete. If you switched over without attaining a period, you could experience some breakthrough as the body adjusts to the altered hormone milieu. The content of the pill also influences the change over. Anyway, you need not worry about failure as protection is sustained. You are well covered. Hope this helps.
