Belly button piercing irritated?

I recently got my belly button pierced around 4-5 days ago and i have been doing sea salt soaks twice a day. Does my piercing have a sign of healing or does it look irritated or even infected? I’m a little nervous due to the redness around the piercing and the bruising around it, but I also had a needle shoved through me a couple of days ago so i’m not too sure.
