Possibly pregnant?

Normally I don't post on these things but I'm over paranoid and need a strangers advice. I'm due to start my period tomorrow. But the way I've been feeling is not the way I normally do. I've looked up my symptoms and there all signs of early pregnancy. Nausea, fatigue, appetite, emotional, hot flashes. I had light spotting last week (possible implantation bleeding) and apparently according to googles help the last time I had sex was the first day I could've been ovulating. Normally I get some type of cramping and an appetite but no cramping but I'm constantly wanting food.
