Laser hair removal causing bleeding/spotting. Could it be the change in frequency?

When I had my first session of laser hair removal done for my Brazilian area, the following day I had a little bit of bleeding/spotting. After the second session I had nothing. I had my third session done yesterday and today I have bleeding/spotting once again (also there's a brown discharge). It can't be my period because I shouldn't be getting my period for another 15 days. Is the laser hair removal causing this? Yesterday, she changed the frequency...could that be it?
