12 days post beard transplant with 1500 grafts.

I had a beard transplant before 12 days , FUT . All the crusts removed. But still planted hair is not falling out .1) Lite black color all over the transplanted area. Is that normal ..?? 2) At chin part , I observed small pimples/bumps with pale whitish color, from which the transplanted hair is visible can I press the bumps slowly . Are they normal..?? 3) Can I trim the planted hair with a scissors to have a public presence at this stage....?? Thanks
