Slightly red boobs

Noticed that the skin over my boobs are always very slightly more red than the rest of my skin. 8 months pp, I pump 4ppd, and an undersuppplier. I pump at most 25-40 mins as I have a slow let down. They don't hurt and I wouldn't have known had I not looked in the mirror. I have noticed this for the last 2 weeks or so.

​

Is this normal? I haven't taken low dose advil since there are no clots but considering it.
