I know the internet can't tell me if I’m pregnant, but I just want to know if it's possible...
the last 2 weeks I’ve had symptoms:

nausea

headaches

cramps

sudden, intense, & urgent need to pee, whereupon i hardly have to go (this has been improving though still too frequent)

sudden, intense, frequent hunger and sudden extremely overstuffed feeling, after eating only a little ( also improving, but still there)

mood swings ( usually between pointless joy and extreme irritation)

fatigue

breast soreness

hot flashes (ugg)

& back pain

also I've been very forgetful lately, but i don't know if that has anything to do with everything else. [?]

Just to be specific: I'm not imagining these symptoms, others have noticed them, and I’m not saying I'm (or trying to be) pregnant. My boyfriend suggested I could be, and from what I checked on the net, the symptoms do match pretty well. Also, I'm not stressed about anything, so it isn't that.

Here's what's bothering me though:
I was supposed to start my period on the 25th. That morning, there was nothing but a pink spot on the paper when i went to the bathroom. Later, at 4 when I checked, I had bled a little, but not enough to even feel wet or uncomfortable or anything.
Today's the 3rd day and it's almost gone. Only a little bit of it's red, it's mostly pink-ish and brown, and most of it isn't even blood, it's a white-ish discharge, which has never happened with my period, and rarely at all any other time. (it's been continual the last 2 weeks)

Is this even my period? Is it spotting???

I'm afraid that if I'm not pregnant, I have some kind of terminal illness ...

Sorry, this kind of turned into a graphic rant...
