First session of removal and afraid the pico laser was too strong

I am on day 5 post treatment and this is my first tattoo removal. It was on an amateur tattoo already pretty faded and the tech told me I would need 10 sessions to get it removed. This is how it looks 5 days post treatment and I am a bit worried by the looks of it. It is very red and when I did the session she went over it twice and it hurt so bad I almost fainted. Also, I don't see any ink left... Do you have advice on after care to avoid scarring? My tech told me I needed 10 treatments spaced 4 weeks appart and she didn't seem happy that I wanted to pay session by session. She wanted to sell me a package. Thank you :) (Tattoo is on left upper thigh)

First day it was swollen and I bled a lot Second day I kept bleeding and the skin stuvk to the bandais hence the crusts Third to first day : redness is still there, I had some blisters and skin looks very raised on some areas
