Spotting????

Sorry for the pic, but I have been spotting for almost a week ( about 5 days now). My period isn’t due for another week still. Also my periods are ALWAYS really heavy so this is very strange. But I’ve been noticing a little bit of pink spotting. It’s only there when I wipe, and not every single time. I’ve never had this happen before, should I be worried and call the dr or is this normal???
