Help!!

I am 14dpo and AF is due today. However yesterday at 13dpo I startedspotting then it turned into a bright red bleed only when I wiped and I put a pad on for bed and it didn't have much on it this morning. Not like my usual period. I have slight cramps. Nothing I can't handle. I'm scared as I have felt every symptom of preg this month and now I'm bleeding. Does this sound like AF or just a bleed? I was convinced I was preg. Anyone else had this? My periods are usually dark red and heavy. This is bright n light. Not noticed any clots either.
