Scant amount of yellow drainage - T junction opening 17 days post bilateral breast reduction. (photos)

I am currently POD #17 from a bilateral breast reduction, uncomplicated and everything went as planned. I had my steri strips removed yesterday, and have dissolvable stitches. Upon returning home, I can now see at the bottom of my left breast on the T-junction there is an open area, with white/yellow tissue that is slightly draining (I have gauze placed over top). I have been applying vaseline to my incisions. I am wondering if this is an infection? I will be seeing my surgeon in 2 days.
