Intraoral chin implant 7 days post-op - lower lip looks small, weird and covers my lower teeth. (photos)

I had chin implants 7 days ago through intraoral and most of the swelling is gone. My concern is, my lips looks weired and smaller than before. When I talk long, I feel muscle cramps on my chin and needs to stretch my neck for a bit. It also feels very stiff when talking. I cant smile properly as I look like a goat conpared before. Im worried the implant is too higbor is this normal?
