After a CO2 laser treatment....i accidently scratched it!!!

I recently had the CO2 laser treatment for four moles on my face. I accidently scratch one of the places (where it was dented from the laser) and now it's two times (or more) the size that it was. It's red and I can still see a tiny black spot in the middle. What happened? Did I just ruin it by making the scar bigger??Would it ever get better?And does the black spot mean that I have to do a second treatment since its not completely removed?
I just removed the plaster for another spot but it is SO -bloodish- red!!!I don't think it's supposed to be like that since it has been more than a week since the laser treatment and the doctor said it's supposed to heal completely.
