Why do I have a Cleft Chin after my Chin Implant? (Butt Chin) Will that go down and form into the smooth shape I want? (Photos)

I got a chin implant and everything looked wonderful, until my doctor took off the bandages, and then I saw in the mirror that it was a Butt Chin/Cleft Chin! I didn't have this before the surgery. The doctor inisisted it being a muscle forming it and the nurse beside him said it'll go down in a week or two because of the swelling. But I don't buy it, it looks like an unattural butt chin. I really hate it. I wanted my chin to be pointy, not cleft like. What do you think?
