I received my Lady Cup Pink Cup the other day and decided to try it out today since my period should be starting any day now. I know that I'm very small inside and this is one of the smallest cups right? Problem, I can't even get the dang thing in. I can barely get the top ring in and it pops open. I tried to find instructions on the different folds on here but couldn't...I think I'm using a c-fold. Any advice would be greatly appreciated. Thanks.
