Bellybutton Infection

Okay, so, I don’t know how long ago my piercing was done. I let my friend Melynda do it. It was good, good, good, good, for weeks apon end. I’m sure it hasn’t been a full month yet. My friend Jessica’s peircing got infected. I called her to ask her what it looked like when it is infected. She said it was red/purple on the tip of hers. Mines not red/purple. It’s still new, so it’s still kind of a red color. She told me to use Sea salt to clean it, but it was hard to find around my house. So My other friend Jessi gave me her piercing cleaner for her ears, we mixed it up with rubbing alcohol. That worked wonders. It felt great. Then My mom bought me a new ring. So I switched rings, then I ran out of the piercing cleaner/rubbing alcohol. So I found rubbing alcohol around the house and used it. My skin had a reaction to it so I switched over to Hydrogen peroxide. My sister saw Melynda and Melynda said to keep up with the sea salt, So I just cleaned it with some sea salt. It hurts, ever since I got the new ring. Is in infected or what?
