8 days dpo

Amanda • My husband Ray and I have been TTC for 14 years now. Please give me love and baby dust. We are leaving this all up to God and having faith
Feeling sick like a cold sore throat. Cervix is high soft and closed with sticky CM and was having brownish pink discharge for 3-4 days. Also experiencing cramps and a headache along with fatigue. I have been getting BFN. Can someone tell me what is going on. Am I expecting implantation or early pregnancy symptoms?
