Infected stick n poke.

Okay okay before you judge me I was drunk and stupid I know it was a dumb decision please don’t lecture me about it I feel stupid enough as it is. I got a cute little heart on my finger but I’m growing more and more concerned that it’s infected because it hurts when I put and pressure on it and it’s very red around the area not swelling v much but it did bubble up when I poured hydrogen peroxide on it. So I’m sure it’s infected a little bit at least. Besides going to the doctors is there anything else I can do please help! I know it was so stupid I was drunk and my friends told me to so I did my fault 100% but please help me! Should I cover it with a bandaid or let it breathe? What products should I use?
