Period???

I’m not sure if this is my period or not? I’m wearing pads but there’s never anything in there it’s just a little brown every once in a while. When I pee sometimes there’s stuff in the toilet that’s like a very dark red brown discharge. When I wipe it’s brown clots and discharge and stuff sometimes with the smallest dot of red or light red. This has been happening all week. Idk if it’s my period or not, it’s happened before so I’m not sure if it’s ever my period when this happens.
