Help!

I'm currently 17 weeks pregnant with my first and I've noticed both of my breaks seems to be slightly red. Not just a red spot but all around. It doesnt seem to matter if I'm wearing a bra or not. My next appointment is still 2 weeks away so im trying to gage in I need to call my doctors office on monday or if it's normal and I can wait until my next appointment to bring it up.
