Spotting on and off

Ok so I have been spotting on and off since yesterday around 4:35pm and it’s never enough to fill a tampon or pad. Like it’s only when I wipe and it’s a very very light pink and it’s watery and my period is due today. I have been having period like cramps but there not because these I can handle lol and I have been tired but last night I just couldn’t sleep at all. Just want to know is anyone going through this or has went through this? If so let me know what’s going or what happened to you.
