Is my dermal anchor infected?

I have 3 dermal anchors under my left collarbone. I got them done in July, and they've been pretty okay since then. The couple months after I just got them done I washed them a few times daily and tried to avoid them getting hit or pulled at. After the first month or two, they seemed like they were rejecting so I would push them in or put bandaids over them so they would heal better. Only 2 of the dermals really seemed to be rejecting the most, one of them was always pretty healthy. I still wash them as often as I remember with medicated soap from my piercer.. Today I was pushing and twisting a little bit one of the anchors that was rejecting. It was a little red, but after I got home it seemed fine. No pain or redness. But just tonight, I looked at my dermals again and the healthy one had puss around it. It hasn't been sore to touch, red or anything. It was always the least problematic anchor. I washed all 3 of them immediately after I saw it. Do you think it's infected? Is there anything else I should do?
