Pain in the stomache after heavy stretching

Anyone else experienced this? It has happened a few times before, but I had a intense session today and few minutes later I started feeling the pain so it’s no doubt that it’s from PE.

Seems like the pain is coming from the area around the belly button.

You need to be a bit careful — think about what you are pulling when you stretch. Chances are you overstretched a muscle or ligament — they do connect all the way back up. Rest it (go easier on the stretching — still stretch if you want) until it goes away and work back up more slowly.
