early pregnancy symptoms

So I'm waiting for Tuesday to come around to test but I'm having a lot of signs and I want to know if anyone else had these signs too. I'm very emotional, I get dizzy at a drop of a hat, my nose is stuffy/runny, I'm bloated like crazy, I have gas which isn't normal for me at all, and I feel hungry 24/7 but when I think about eating something it just upset my stomach! It's driving me crazy because it's making me think I'm crazy! Help please!
