you are still healing. I can't tell from the picture if the left nipple is discolored or its just the angle. It really doesn't look that bad.
Even cis men have nipples that are not exactly even. Have you ever placed something over half your face, looked in the mirror and then did the same to the other side? Most people are not completely symetrical. It just looks like it. Once the swelling goes down and the last of the sutures are out, you may feel better. If you have any concerns as to possible infection, have your Dr. check the site.
