I am in my 4th week post breast reduction (age 69), having red/brown spotting at the T section under each breast. Sound normal?

T wounds are also deep and seem to be getting wider there, but there is no sign of infection. I continue to do the once a day dressing of of the incisions after shower with Aquaphor, treated (yellow) gauze strips, and gauze pads under the compression bra given me by my doc. I feel well other than slightly worried about the very slow healing. Does this all sound normal?
