Got my navel pierced today, it's a little slanted?

My friend had it done with me too, and hers looks more crooked, the piercer didn't use clamps on either of us, my friend went first and I asked him about the piercing looking crooked on her, and he said it would fix on it's own. Is this true? I know, no piercing is gonns be 'perfect' but I think he could've done a better job, I just want to know if it will eventually look straighter. You can't tell mine it's slanted unless you really look, but I'm a little of a perfectionist, and it's just bugging me a bit.
