I started to work on my muscles , needed a change but my chest looks weird I need an advice from bodybuilders?

I started to workout about 1 month ago and it is starting to show , I had 56 kg and now I have 58.5. The thing is that my chest looks weird , My pecs are growing but I can stil see the bone in the middle . It is kinda weird bone in middle and muscle on the sides . I usually do push ups and lift dumbbells . I need something to put some muscle mass evenly . Or should I just keep going and It will go away by its own?
