2 weeks post op from Breast Reduction, and I possibly popped(?) an internal stitch, and my surgeon is on holidays!

I was trying a dress on today at a store, and while attempting to take the dress off over my head, I felt a slight pop in my left breast. There has been a little bit of pain but nothing serious, I am more so worried and I can't see my surgeon until January 5th! No signs of bleeding, will I be okay until then or should I go to a clinic or emerg?
