Help with piercing please!!!

Laurel

I got my nipples pierced over two months ago, I haven’t had any issues with it until now. I definitely think one of them is infected, it isn’t swollen or red or anything right now. But it does hurt, and there’s pus coming out of it and I’m a little worried. Is there a good way I can treat it at home? Or should I just go to the doctor and get antibiotics? I’m a little scared!!
