Someone tell me to stop being psychotic...

I thought I was out today. I woke up about 6am with some pretty bad cramps (resembling AF that isn't due for another week!). I went to the bathroom and no blood. Took a morning bath (sometimes it helps) and checked again. Very watery pink blood (still extremely light spotting)... so I figured I would just put in a tampon (8am) and watch some sappy movies and get ready to start over for this month. Around 3 pm I was wondering why I hadn't felt the need to change, so I went to the bathroom to check my flow and hadn't even filled 1/3 of it.

So the real question... is this my period? I haven't tested because I'm still a week out from AF. Usually I'm a crime scene from day 1. Does anyone have experience with this?
