Rare period

Hello Ladies,

So this month my period has been a little weird and I need some help with understanding what is going on. My period is normally 8 days and i spot the first day and then heavy/medium the next days. Well this period I was spotting the first 2 days with really light pink and not so much of it. The 3rd day it was a light flow and a bright red and then the 4th day it went back to really little pink almost nothing. Now 5th day I have more of a very little brown color. What does this mean ? My period has never been like this can anyone help me please
