Crease in upper and lower belly button area? (Photos)

Hi! Im really concerned about the crease in my upper and lower belly button, my dr says it will go away, i didn't have it in the early days after post op but then it appeared and never went away! Is this permanent? What should I do about it? My friend have surgery at the same time and she is completly flat (another surgeon and a longer incision) and i have been looking for photos of people with 6weeks tummy tucks and ALL of them are super flat. Thank you!
