As of now I am 7 days late on my period. I have been feeling a little tired lately and dizzy. But other than that nothing much. I recently took the birth control depo-provera , it didn't do me so good. So I only took the first dose and that is it. It was supposed to stop being effective in October and we are now December and I have missed my period. I recently had a baby 6 months ago and am hoping not to be pregnant again so soon. I'm wondering if it's the Depo that is doing this although it shouldn't even matter anymore b/c it has not been effective since October or could I be pregnant?
