Asl

I am confused. I am 13dpo and i hv this from yesterday (12dpo) i thougt it stop but it came out again today night. My Af due in the next 2days. Oh gosh could it be implantation bleeding or just early period?but generally when i hv period,i hv brown spot too and right away with period blood. This time isn’t like usual...so i was thinking this is implantation bleeding but not sure enough,what do you think?
