Question about brand new ear piercing?

I just got my ear pierced two days ago, the piercing is located about halfway up the side of my ear, like just before the cartilage begins. The skin around the piercing is turning a kind of grayish color, and i was wondering if this is normal? Like maybe it's just a bruise? It was professionally done, and the jewelry is real and sterilized. Also, there is no discharge from it at all, which the guy told me to expect. But is the skin discoloration normal?
