mid cycle spotting

my period is due in 5 days , i’ve been spotting super light for the past 3 days not getting any heavier . has anyone had this happen to them ? what was the outcome ?

also - normally if the spotting was my period starting up i’d spot for a day and it’d get heavier till it’s my normal period flow but this is super pink , i had implantation bleeding with my first but it was 3 days before my period was due and i only spotted for a day
