Belly button piercing

I just got my belly button pierced yesterday and when I bend over the bar slides out of the hole more which hurts and I was wondering if this is okay for a healing piercing ?

Update: i mean that when I bend over my skin folds a little and the bar slides up some and more of he bar shows at the top of the piercing. No balls come off or anything like that. The jewelry just moves up and down which hurts. I’m just worried since it moves so much and my piercer told me to never try and move my jewelry
