It's difficult to get a clean shave on my face few days after laser beard removal. Is this normal?

I had my first laser beard removal session 4 days ago, and for past 3 days I cannot get a clean shave at all (I can still see and feel stubble). The clinic told me it's normal because the hair is burnt so difficult to shave off. Is this normal after treatment and before hair starts to get pushed out or fall out? Some follicles seem to still be a bit bumpy or swollen, and overall the skin on my chin and along the jaw line seem less smooth (more bumpy) than before.
