Tests keep saying negative and doctors wont help

So I have been having pregnancy symptoms for two months or more. My stomach is hard and I'm nauseous. I have back pain and cramp really bad. When I lay on my back I feel pressure in my abdomen and get really nauseous. My "periods" are very light and I'm always hungry. What do I do? Could I be pregnant and the tests are just not reading right?
