Question
I was due for my injection on 10/25/10 and i started the pill im down to my last week with the pills that your period cum on but mines haven't is it possible im pregnant or i need to give the pill some time.

Answer
Some women don't get periods on the pill.  Since you had been on depo provera, which thins the uterine lining, that may contribute to your not getting your period.  If it's time to start a new pack, and your period hasn't come, I'd do a pregnancy test just to be sure.  As long as it's negative, I would just keep taking the pill.  In case your period doesn't come next month, you could ask your doctor to switch you to a different pill, and your period would probably come.  However, some women don't have periods on the pill, and there's no medical reason why you must.
