Is this swelling or are my nostrils going back to how they were? (Photo)

I've posted three pictures. The first are my nostrils before my open septo- rhinoplasty, the second is with cast and stitches. I loved the shape! But, the third is today, 3 and a half weeks post op and I can see my nostrils are starting to form back to how they were before my op and I'm so upset. They look uneven again. I love my side profile at the moment but I'm sad about my nostrils. Any opinions?
