I'm so confused...

Ive been spotting for the last 5/6 days.

I most never experience spotting. My periods are heaviest day 1-2, then medium day 3, light day 4 and done. This or some similar variation.

I started spotting on 9dpo. Dark brown/dark red in color. Only saw it a few times that day.

10 dpo, same color spotting but even less in qty.

11 dpo - dark brown blood with bright red blood. Put in A tampon thinking it would get heavier. Took it out 8 ish hours later, almost completely dry, probably could have gone without it.

12 dpo - decided to use my diva cup. Wore it for 12 hours, measure slightly under 7.5ml

13 dpo - same spotting at before, negative pregnancy test. And today 14 dpo almost no spotting. Is this my period? Why does my temp keeping going up and down? Possible Eptopic? So many questions. I'm making a doctors appointment this week
