Cut on armpit + laser. Is it safe? (Photo)

I have my first laser hair removal treatment tonight on my underarms so I shaved for the first time last night (I always used hair removal cream). Because of my lack of experience, I cut my underarm from swiping the blade sideways trying to get a stubborn hair. It’s a shallow cut but I’m worried about what will happen tonight when they Laser on top of it since it isn’t FULLY healed. Is it safe to laser on top of cuts/wounds? Will it hurt? Will I get a scar? Do I have to reschedule???
