Do I have an infection? What should I do? Spitting stitches after breast lift.

I had a lift with 200 cc saline implant 15 days ago. I visited my PS yesterday bc I had concerns of fluid. He said I was fine. Did not remove my tape. Today, I noticed very gross yellow puss leaking through tape. Remove it to find raw skin. And 2 clear stitches poking out. PS didn't seem concerned, told me to clean and dry it. He also said to grab stitches with tweezers and pull and clip. I clipped but when I tried to remove them they were stuck and I began to bleed, no antibiotics. What 2do??
