Spotting

Hai. Semalam sy ada bersama suami. Pagi ni bangun tengok dekat pantyliner got some light spotting,pinkish dark brown gitu. Semalam bersama takde sakit atau apa. Today is my 6dpo. Is it spotting, implantation bleeding or my period is coming? Kalau ikutkan due period lambat lagi. More than a week. Nak bt upt pun masih awal lagi. What do u guys think? Need some opinion. Thank you
