14 dpo. Period or late implantation? BFN. Anyone else?

hello extremely new here. need help. 14DPO, Af is due today. Having this "period" right now. And im having some bright red bleeding. put a tampon and its not heavy, like it usually is. It first was brown as always, then turned to bright red. No cramping like it usually is. doesnt leak into liner. just stays there. All BFN still. anyone ever have this and then got a bfp? Im gonna wait it out and see. And then accept my fate. Thank you please answer.
