All the symptoms

I'm having all the symptoms of being pregnant for the past two weeks. Took a pregnancy test and it came back negative. Suppose to start in 2 days. We had a pregnancy scare one other time and next day ended up starting my period. Could this just be another scare or am I really pregnant?! My boobs have been hurting, been tired, nausea in the mornings and my food intake has gotten worse. I'm one of these people on where I'm stressed I don't eat, I can't eat otherwise I get sick. So is there any chance I could be?! Please help
