Chin Implant Very Round and Made Face Too Long from Front View

I am one week post op from having a chin implant. I absolutely love what it has done for my profile, and in that regard I wouldn't want to go any smaller, but from the front my face looks so much longer. It also looks like I have this rounded chin and then my cheeks come out instead of being one flush line. My surgeon tells me that as it heals I should get an increased sulcus and it should pull up on the implant resulting in less length from the front view. Is this true or is it placed wrong?
