Belly button piercing- 3 days old- infected?

Am

I got my belly button pierced on March 3rd. I wear mid rise jeans with a belt and I keep a tank top tucked in. My work requires me to bend over a lot or pick up heavy boxes.

I clean the piercing religiously with warm water and the salt spray I got. Is this just irritation or infection? It’s not oozing pus or anything. The bottom side isn’t red, just the top side.
