My stomache isnonstop hurting its kind of like cramps but im not on my period nor starting it, could it be an ulcer?

Many possibilities. Your crampy stomachache could be due to many possible causes including viral infection, irritable bowel syndrome, gallstones, pancreatitis, gastritis or pregnancy. An ulcer in the stomach or duodenum is certainly one possibility. See your doctor if it continues to bother you.
