Sorry you got no responses before this. I’m in the same boat but only 1 & 1/2 weeks post op. Still having serous drainage at this point. Sounds like I had similar surgery to yours. The drainage is the worst part at this point.
Changing my underwear several times a day. But it’s not a sign of infection and has more to do with the extent of your surgery. Plus, healing is delayed by BM’s. Onward and upward!
