Spotting 6 days before period? Implantation bleeding?

I am on Junel birth control, and all of the sudden this month I have began spotting three days ago (9 days before period) and I’m still spotting now? Why??? It’s very light, and brown with some small clots. My boyfriend and I went raw a week ago, and he pulled out but I fear some might have gotten inside. Although I take my birth control every day at the same time.. could this be implantation bleeding? Or is it just regular spotting? And yes this spotting has happened before just not in a long time.
