4 days “late” ???

My period was supposed to start on October 31st, it’s now November 3rd and I’ve been having “brown” discharge if you want to call it that, it’s more clear with a brown tint... but not even enough for a small panty liner.

Should this be considered my “period” or could i possibly be pregnant? Tomorrow is supposed to be the end of my period. But all I’ve had is this ^ let me know any input would be amazing
