Is my belly button infected? (Photo)

I recommend you have your stitches removed. They have been in long enough and now may cause more harm with "railroad track" scarring. Stop using hydrogen peroxide too. See your surgeon. Best wishes. 

First of all, your navel needs to be packed to help your belly button keep a good round shape. It doesn't look as though you have any packing it in. You do not look infected. The skin around your sutures is just pink. This will get better when your sutures are removed. I would call and ask your surgeon about packing your belly button. Good luck!
