pregnant or pms šŸ¤”

Once again I'm in a position where I don't know if I could possibly be pregnant or just having some pms symptoms. Saturday I had light spotting it was a light pink color but only when I wiped. It lasted for just that night and hasn't been back since. My period starts next week and I'm just confused as to what this could be. Has anyone ever experienced anything like this before ?Ā
