Is it normal to feel your chin implant on your face?

Hi, I got a chin implant done a year ago and I kinda dont like it at all... I can also feel that I have something on my chin. Sometimes feels like I have something heavy on my face, like ik I have an implant on my face and can feel it. Also when I do a certain expression with my mouth I can see a line on my chin ,. And feel my stitches or is it the implant. I got it done through the inside of my mouth. Any idea why it's like that or is it normal?
