I had my period two weeks ago, and my period isnt due for another 2 weeks, but im cramping now, i never cramp.. what's wrong?

It may be unrelated: to your period. It may be a gastro-intestinal problem like acid-reflux disease, IBS (irritable bowel syndrome), gastritis, etc If the symptoms don't resolve, you should see gastro doc who can do further testing. IBS is becoming more common these days - if you tend to have constipation or diarrhea or both of these intermittently and consider yourself an anxious person, this may be it. Feel better!
