Need advice or help with belly and abs :(

I've lost most of the weight and inches that I wanted to lose, but there is one thing still bothering me. The area just below my belly button is still swelling out too much for my liking... and I can't seem to get rid of it, no matter how much I work out with cardio, abs, and other strenght training. I did the 30 day shred (didn't complete it because of injury) and I am now doing 6 week 6 pack.
However, I've noticed that when I tighten my abs (which have gotten really strong), it also creates a bump. Is it possible that part of the bump I can't get rid of are my abs that I keep strenghtening? I'm not looking for false hopes, I'm just not sure what to think of it now.
