Breast reduction incision has opened and a stitch is sticking out 2 weeks post op, should I be concerned? (Photo)

I am not too concerned about the incision opening itself, it's not infected, no more drainage, no odor, etc. however I remember reading that if there is a visible stitch it could delay healing and cause complications. I canceled my appt with my surgeon because I think it looks fine and it's already healing, but is the visible stitch concerning?
