First, I never get cramps for the most part I just ignore my period. Second, today I had excruciating cramps every three minutes along with nausea, vomiting, diarrhea, dizziness, shaking and cold. Drank maybe a cup of water and 1 Aleve and after about two hours I fell asleep and woke up like nothing happened. Any idea what it might have been? Definitely not pregnant, 23, no meds, 35-45 day cycle, average 38 days
