wet-to-dry dressing getting worse?

hi y’all, i’m 4WPO today and i had a small opening on my t junction that i saw at 3WPO and went to my surgeons office, they told me to do wet to dry dressings with sterile gauze and saline which i’ve been doing. it’s been a week now and i feel like it’s getting worse. i didn’t take the best pictures bc looking at it makes me feel queasy, but every time i change the dressing there’s some puss/yellow gunk on the gauze as well. i have a facetime appt with them tomorrow (i just moved across the country from them) but i feel like this isn’t working.

maybe im just impatient though. have any of y’all done wet to dry dressings and how was that like for y’all? when can i expect this hole to close up??
