It is quite possible that this represents a capsular contracture on the right side. If the right breast appears to be getting more firm and higher on the chest wall with time, then capsular contracture is the likely diagnosis. The other possibility is that the right breast implant pocket was not fully dissected or that you had some notable asymmetry before surgery. If this is the case, then the right breast would not be changing much over time. If you do have a contracture, it can be corrected with another procedure. The chances of having another issue is higher once you have developed a capsular contracture, but it doesn't mean that you can not keep or exchange your implants.
