What do you think?

So I've been feeling bloated for the past few weeks. My appetite has spiked, I'm getting frequent headaches, my lower back hurts, my breast or tender every so often, feels like I have to pee more than usual, and I feel tired more than usual, and I get nauseous here and there. I'm supposed to have 2 periods this month. My first one was just a day of light spotting to nothing compared to my 7 days of heavy bleeding. I'm trying to hold off till my next period before I take a test. (Week and a half away) What do you think?

I keep having dreams of being pregnant. I don't know if that is a sign.
