Hello, I Had A C-section Last 2012. Recently I Have

Hello, I had a C-section last 2012. Recently I have been exercising focusing to loose some fat in my belly and stomach part. The exercise is only light but I feel it was really doing the job to burn my fats. After a week or two of the same routine, I feel some pain in my lower right abdomen specially when I sneeze. I am worried because maybe this affect my C-section wound that causes the said pain?
