Spotting implantation??

Well im 3days before my period comes and i just spotted like brownish and a little light pink... just tested negative on saturday, was waiting for my period not to show..but could it be implantation bleeding??? i have light cramps just on one side...

Any ideas ?? Is it just my period coming?? Or could i be pr😳🤞🏼🤭
