Early pregnancy

Goodpm po last mens ko po jan 4,2021 and regular 28 day cycle po ako. Last feb 5 nagpa serum test or qualitative blood test po ako kasi unusual po skin madelay. Never po ako nadelay. And turns out positive po ang result . Im so happy and my husband po .but just by feb 8 until now po may lumalabas po saking dark brown or parang old blood color po pero almost half of panty liner lang po mapuno nya . I was wondering po if is it normal po or just got my period? Delayed lng po ako? Any insights or advice po is highly appreciated po. Salamat po
