weird period or late period

last week I started spotting a dark brown, which sometimes happens before my period. Then I thought I was starting my period, I had dark red spots with some clumps so I would put in a tampon then there would be hardly anything in it. I'm on the pill, have been for over a year, three months ago I started a different brand but my doctor said it was pretty much the same thing. My boyfriend and I have raw sex and he pulls out, the last time we had sex was Oct. 29th. I get regular periods usually but I'm wondering if I actually got my period and it was just super light or if I'm actually two days late. What do you think?
