Is this the beginning of an infection? (Photos)

I had a breast reduction/ lift and augmentation 13 days ago. Due to blood flow during the surgery my ps only out stiches in the right nipple every so often leaving gaps so the pressure wouldn't build up and cut off the blood supply to my nipple. I have been dressing it daily with xeroform, chlorsig and gauze. I've just taken it down and seen this. Is this the beginning of infection and should I message my ps right away, my next appointment is 2 days away. Or change the dressing and wait.
