I just don't get it!!

So here is my dilemma.. I have a 26 day cycle and bleed for six days. I started spotting a day early which I only seen a little when i wipe couldn't really even tell it was light light pink. The next day it was a slow and light flow reddish in color next day really really light flow, same color is not darker yesterday hardly anything Brown and red. This morning only dark old blood just when I wipe. This is so not normal for me usually from day one to day 4 it a med to heavy flow with day 5 slow flow and 6 spotting. I don't know what to think. I hate this feel like I am going crazy. My period have never changed
