Im so...I dont even know the words

Yesterday I got a faint positive plus sign I was excited finally Im pregnant. Today I took a digital and it says not pregnant. I don't which one to believe. My period still isnt due til the 2nd. Is the digital wrong? Is the plus sign wrong? I dont know! Im bloated cramping very emotionally. I want to take a million more tests! Has this happened to anyone? Whats your thoughts?
