Spotting ?

Has anyone ever had a period, and then the day after it mostly stops, start spotting pink??

For example my period started Thursday 8/1 supposed to starts 8/3) bled red until yesterday (8/5) and then brown from yesterday until this morning. (Assuming my period was ending)

It’s 1pm here and I just used the restroom and noticed I’m spotting pink? This hasn’t ever happened to me before?

What’s going on?
