First period since stopping birth control and bleeding over a week???

So I stopped taking my birth control a little over a month ago. And I was supposed to start my period last monday, which I did start bleeding right on time. But it's different that what my periods usually would be. It's just been very light dark and bright red bleeding which I only see when I wipe and it doesnt fill a pad. And there's some tiny clots sometimes. It's now Tuesday and I'm still bleeding. What the heck
