Suggest Treatment For Nausea,stomach Cramps And Pain

Went to sleep a little nauseous. 30 minutes later woke up feeling sick to my stomach and ran to the restroom. When I got there I no longer needed to vomit, but I began having stomach cramps that felt exactly like contractions, about less than a minute apart. I am NOT pregnant. About ten minutes passes and my stomach still hurts a little, but no longer contraction like.
