am i pregnant?

Samantha

I have been feeling sick, smells make me sick, I'm always tired, I get more headaches, I pee like every hour or so. My lower back hurts like hell. I have been craving foods that I normally don't want and my boobs feel heavier. My period is suppose to show up Wednesday but I have no symptoms for that and I can't get a test until Thursday but I really want to know.
