I have an inverted T open after Breast lift. Any suggestions? (photos)

my incisions split 4 days ago, I'm now 15 days PO after a full anchor lift with sub-muscular silicone implants. The hole is getting bigger. There is no pain (just stinging when washed), no redness, and the drainage doesn't smell bad. My Dr keeps assuring me it's common, and it will heal to just keep it clean and covered, but it's getting worse. I'm concerned and want to make sure I'm Taking care of this right. How long will it take to see improvement?
