Are there any 20something year olds here that use a size 2 (bigger size) lunette? I am considering ordering another cup because my small size diva cup leaks every time my period is strong. I'm 21 and have no kids. The difference in diameter between the cup i have now and the larger lunette would be about 4.5mm. Do you think i should go for it and order it or be more conservative and order the smaller mooncup uk which is 1.5 mm larger in diameter than my old cup.
