What Causes Recurring Cramps And Pain Around The Abdominal Area?

hi for the past year I have been experiencing cramp and pains around the abdominal area. I have been to the hospital twice and had the ambulance out to see me as I wasn t quite sure where the pain was coming from, the ambulance came out and checked my heart which he said was fine, I since visited the hospital where I had scans on my kidneys and blood tests undertaken, which all came back healthy, which then led me to think it was to do with my stomach, as I had a termination around about a year ago and didn t return for a check up scan as i thought at the time it was all fine, these pains seem to come and go at weeks at a time but when they do I feel as though they are getting worse and harder to deal with, could you please help?
