So confused..

I have a regular 26 day cycle with 6 days period. This month I started a day early with light light pink spotting then second day light flow, third day really light flow, yesterday dark blood spotting, and today nothing. What in the world is happening I have never in 31 years since I started my period had that. Any ideas. I know implementation is different for everyone. Been ttc since June haven't had any success. I know everyone is different in my heart it says to test but my mind is saying don't even waste you time nor money. Here is my month tracker.
