TMI Brown black discharge instead of period

I'm 8 days late now and still cramping on and off.. when I'm having my AF I always get the red flow first.. so Idk of this is the start of my AF.. it's creamy black brown with watery cm..

Update: 9th day no AF and brown gone.. I'm like having second thoughts retesting cos I dont like to see another bfn lol haven't tested since yesterday so maybe if still nothing will retest if I'm 12days no af? Check my cervix i see my finger it has very light brown and it don't smell like AF blood so no idea

Update: no af still and no more of this just thick Ewcm
