Hi my exboyfriend was physically abusive to me. Once during an attack he threw me to the floor. I landed on my back and he jumped on top of me. His knees impacted me directly above my belly button. Since then I've had stomach swelling in this area. This area is now bulging above my navel. Don't know if it's from having three children - youngest is now 19- I'm 45.... Anyway it looks like I'm pregnat from the front and side view. All tests have been negative. What should I ask the doctors to test ? What body parts are in the navel area ?
