Rejecting or longer bar?

Im worried i need a longer bar/poercing is rejecting. I got it about three weeks ago and it doesnt hurt but the top ball is making a small crater. Nothing that hurts, just irritatedm I went back to my pierced and he said he had no longer jewelery for it and that the small crater should eventually harden up. I havent changed it and have been cleaning it routinely as i was instructed. Any help is greatly appreciated!

(also i know i shouldnt be touching/moving it, i just did that for the documentation)
