Is my lipo hole healing properly? Does it look infected? (Photo)

I had lipo and bbl 3 weeks ago and I'm experiencing delayed healing with one of the lipo holes. I've been cleaning with mild soap and water daily and covering with gauze. Not sure if it's getting better, Do this look to be healing? What is the yellow film in the inside of wound? Will that heal on its own? I have no fever or any other symptoms of infection. I'm very paranoid just want to know it will heal and have peace of mind so I don't worry about it daily.
