Hi Mermaid,
I'm in exactly same situation as you. Got my first laser session on my face 9 days ago, and my first hairs just started popping out now. This is normal apparently.
My technician told me that the hairs would come out at the 12-14 day mark. Her explanation was, the laser destroys the bulb of the hair, but not the shaft, which is still stuck in your skin, and your body will slowly push the hair out.
For the first week, it looks like they were "growing" just like before. The only real noticeable effects were a) rough bumpy skin, b) slower "growth", c) the hair would refuse to be shaved... it's like it was rubbery or something.
Indeed, at the 9-day mark I can grasp a hair in my fingers, and pull it out with no effort and no pain. It's pretty obvious they're not anchored in there anymore. However, my tech advised me not to pluck them early for some reason, just let them come out in due time with normal shaving.
Edit: about the pain - I also had the same situation (jawline was extremely painful, mustache was painful but bearable, cheeks hardly felt it at all). I think it may have something to do with the jawline being right on top of bone, kinda like tattoos on top of bone hurt more. My other theory is hair density and darkness - my cheeks are really sparse and somewhat more orange, but my mustache is dense and dark.
