It takes a six to eight weeks for the normal swelling to go down after surgery. Sutures are designed to hold tissue together long enough for the body to heal in the right way and then to dissolve. Appearances change very rapidly in the post operative appearance so I wouldn't worry or obsess as long as you are feeling better each day. See your surgeon.
Swelling along the perineal suture line is temporary and subsides when the sutures dissolve in a few weeks. Keep the area clean and don't worry about it. The final result should be apparent in 6-8 weeks.
I don't mean to be rude, but only to comment that all of your questions should be asked to & answered by the DOC WHO DID YOUR SURGERY (you know, the one you PAID!) Surgical fees, to my mind, include full pre- and post-op preparation, care, and ongoing "question-answering," not just the surgical procedure itself... That said, I truly cannot begin to accurately answer your very appropriate questions without an in-person evaluation. It takes a full month before you'll be able to get an idea of your post-op appearance. At that time, if you are dissatisfied with results, you can discuss with your surgeon, or see another specialized gyn plastic/cosmetic surgeon who can revise to your exact specifications. The attached weblink can give you an idea of what perineo/vaginoplasties look like @ 6 weeks post-op...
Very best wishes!
