Urgent - Help! Want it to go away!

I think I may have a belly button infection. Sometimes a white, smelly discharge kind of substance comes out of my belly button and I’m just wondering if there are any home remedies to get rid of it as I’ve heard that you don’t always need to go straight to the doctors for this. Let me know :)

Sorry if it sounds a little gross but obviously it’s something that can happen

I don’t want to put harsh chemicals in it though :)
