Belly button piercing

Okay so one, pls don’t comment on my stretch marks, I have a 1 year old son and I’m very insecure about my stomach, but I’m trying to take pride in it bc it made something so beautiful.

Two , I got my belly button tapered (Incase nobody knows what that means, it means my belly button was already pierced but it was closed up a little bit & not enough to fit a belly ring so they stretched it out) and it’s extremely red and swollen .. I don’t remember the first time getting it pierced it was ever this swollen. Although that was like 7 years ago so I don’t really remember much anyways . But I was wondering if this is normal or if my body is trying to reject it ??

If you know, please help me out , thank you !!
