Weird symptoms please help!!

For some reason I feel that I am pregnant and could say that I am. I've never had heart burn and seem to now, very hungry, and emotional. I am also bloated. Get dizzy when I get up, have a rapid heart beat that feels like my heart is about to come out! My breast aren't sore but get tingly sensations. Sex drive is way past normal I think. Teeth feel sensitive but no gum bleeding. Lower back pain and have been peeing like crazy!!
