Spotting after sex? Early period after Pap smear?

I usually have very light periods. This time it came 3 days early, which was a day or two after my Pap smear. My period started dark blood, and brown, and heavier than usual. I had sex a few times and my period I thought had ended yesterday, but then I had sex again and I still have a bit of blood about every other time I go to the bathroom when I wipe. Everything seems normal but just extra spotting. What's going on? Is my man just hitting my cervix or what?
