My invisalign are not fitting my teeth properly. (photo)

Hello,I am on my 24th tray of my invisaligns.My teeth are still not straight.My tray is not fitting the buttons and my teeth.I feel so much pain even after wearing them for a week.My dentist thinks its alright.She also placed brace locks and elastics but it seems like ita pushing my teeth the opposite way.I am so upset,she is such a great person.I dont know how to bring it up.I was looking forward to the result but now I feel like my teeth will never be fixed.
