period with bc

so I'm supposed to get my period soon and I got the depo shot during me period last month but ever since that I still have had bloody doscharge everyday (side effect from shot) so now I don't know if I'll just continue through that during what should be my period because (sometimes you don't get your period on the shot) or if I shud be expecting to get my period even though I've had irregular bloody and brown discharge everyday.. anyone have anything like this on the shot or experiences?? what do you think I should expect please help
