What’s happening?

Ch

So my period has been over for 3 days now and this morning I went to the rest room and when I sipped I had super light pink on the toilet paper I thought maybe I was seeing things so I tried wiping again and it was the same, so I wore tampons today and I have had an extremely small amount of brown blood on each one when I changed them. What in the world is going on? Had anyone experienced this before?
