Thanks for your replies.
I realize that stress can cause changes to your period, and maybe I'm being too skeptical but I have been under a tremendous amount of stress before and my period was unaffected.
I'm also really afraid to take a pregnancy test at the moment. I am on a really tight budget because I have to get prints of my photographs made for my finals this week and don't really know how much I can spend on one, or if it is even a good time to take one since my period isn't supposed to start until the 11th. So i wonder if I would take one, get a negative result and yet it not be accurate.
And maybe I am just being too freaked out by this but last night I stopped bleeding for the most part. Now I really am only spotting (granted I've never really experienced spotting before, but I don't have a way to describe the amount of blood. it is way way less than normal but more than a few drops...)
and today I am super bloated and my stomach is still churning and I keep having to run to the bathroom.
I have had an almost constant headache today as well (but only about an hour and a half after i got up this morning I ended up crying and I'm unsure if the headache is linked to that or not). But just leaning over (this began last night) is almost intolerable because my back starts hurting so bad and I have to find something to support it or it drives me crazy.
I am just worried because I feel sick today, more than I did the last few days, and yet my bleeding has subsided substantially. And my cramps are worse than they were yesterday and I normally never have cramps after the second day, and now I am having them and they are worse.
Are there any reasons beyond stress that would cause this? I'm just really trying to keep my eyes open as to what could be causing this since it is so terribly different from my usual.
And I am shying away from believing that this is related to pregnancy as well... just because I think I was bleeding too much for that to be the case yesterday and today even though it was lighter than my normal period would be.
