Random pain, only happened one time and lasted two seconds

But it was very painful. So today at work I was just standing still and I randomly got a sharp feeling in my gut, it felt like round ligament pain but I thought I thought it was weird because I wasn't moving or anything, just standing still. Has any one else had this happen or know what it is? It was on the right side of my belly button and ran vertically
