Injection site

I currently use pen needles for my insulin, I inject it in my sides (love handles) is this wrong? I recently started to inject nearer to the center of my abs. 



I have found no wrong site for injection. I mean I tended to use my abs, arms, and legs most often. But I was always told to look for the fatty areas to use, as it cause less pain. The places we use tend to be what makes things more comfortable to us.
