After 1st session of laser treatment (Brazilian) I started bleeding vaginally. If this has happened to others, what is going on?

I got first session done for laser treatment ( brazillian) and i started bleeding vaginally. I have seen that some people have asked the same question here. I just got over with my cycle last week so it can not be period. It heavier than spotting but lighter than period. If other people are asking same thing, i am sure something is happening after getting laser treatment done for brazillian area. I hope i will get an answer.
