is my belly piercing rejecting?

the first pic is when i had just got it pierced which was almost a year ago now and the second one is how it looks now

i know the skin is supposed to swell down but i don’t think it’s supposed to get that small 🤨

i can’t see the bar through the skin and it doesn’t hurt at all which i thought would happen if it was rejecting but idk

i don’t wanna take it out cuz i love it sm but im scared it’s gonna rip through my skin soon 😣
