period? help !

okay, so my period was supposed to start Monday and I've had brown spotting since Tuesday, is this my period trying to come on or could I be pregnant? I usually get brown spotting a day or two before my period and at the end but I don't have cramps, sore boobs, nothing period related. any thoughts/personal experiences would be helpful ! ☺️
