Confused and frustrated

So to quickly sum it up... I’m 9 dpo. Passed two days have had brown cm, back pains, loss of appetite, nausea, and uterus pains like I have never felt before. Today I am now spotting only when wiping but still more than a few drops ( don’t worry I’ll save you from me posting picture 🤢) as well as still having back pains fatigue nausea. I know there is a possibility of implantation bleeding but still to soon my period is never this early I still have 5 days till I’m “suppose to get it”.... had anyone experienced anything remotely close to this?
