Belly button ring: infection healing or regression???

So I’ve had my belly ring for about a year now. It suddenly showed signs of infection: swollen, reddened, and very tender to the touch and brownish puss oozing out.

I immediately began to baby it and used sea salt water to clean it.

Here are pictures of the process it took. It got infected from the new jewelry I had and you can see how swollen it was. I switched it out to the bar I was pierced with to accommodate with the swelling. But as the swelling reduced and the puss is no longer present, I’m still experiencing red-ish skin and the bar is SUPER long to the holes. The last pic is it now.

So is it simply healing from the infection or is it rejecting now??
