pregnancy or not?

i had a period last month on the 17th. i started spotting on the 31st and i had a very light "period" until the 2nd. for two weeks i have been feeling dizzy, light headed, and like i am going to pass out. a few days ago at work i almost did pass out. the only way to make me feel better is if i eat or nap and i find myself sleeping more than i am awake and after i wake up i feel sick... plus i been conspitated.. is any of this sound like pregnancy? the "period" just throws me off... just don't know if it's to early to test.
