Okay, so I am having a problem. I have been on BCPs for over a year now. Ever since I started them, my AF has showed up like clockwork. Never early, never late. Always when it's supposed to be there.
Anyway, this week it seems that my body has gone haywire. I have not even started the sugar pills yet, and my AF should not start until this coming Monday. This past Monday it seemed like my AF was starting. I had the mostly brownish/pink discharge that I usually get on the first day of my period. It was light, and sometimes it would stop, but into Tuesday it got heavier. I also had some mild cramping. However, by late Tuesday night/Wednesday morning, it seemed to have stopped completely. Then later on Wednesday, I noticed that when I wiped, it seemed like I was still bleeding, except it was a very pale red and not very...substantial. If I had to make a comparison, I would say it is like red food coloring in water. I have noticed this pretty much every time I use the bathroom.
So, I'm really confused. I don't know if this is AF or what, and if it is, why am I early even though I am on the pill and have never been early before? The only thing that has changed for me is that I became sexually active with my DBF on the 18th of November. I've had sex before, but the occassions were few and far between. Ever since I became intimate with my DBF, we are, uh, very, very active.

So, I don't know if that would have something to with it.
Any advice would be appreciated. I don't know if this is something I should worry about, or if it's just a harmless fluke? It's been so long since I've had an irregular AF that I guess I just took the fact that I am always "on time" for granted. Thanks in advance guys...
