diva cup helpppp

Jane
Ok so here we are round two of tryna get my diva cup on and im failing once again. The one time it worked last month it was sitting really high. How in the heck can i get it that high again?! For whatever reason it sits low and i know its not doin what i need it to do. Ive spent the better part of my day at work held up in our one lady stall. They probably think im craZy lol anyway any ladies have tips or tricks on how they get their diva cup to sit higher each time they put it in???
