Well heres my story... I had my period once but for like three days and then it went away. I normally get it for 7 days! For the past few weeks.. I have been having all the sympthoms (my breats are tender, I urinate frequently, im tired all the time, nausea, heart burn, emotional) but I took 2 tests and they were negative. I even took a blood test. It was negative too! Please someone help me! Why am I having all of the sympthoms and the tests are negative!
