Why does my largest cup always leak?
I have a small diva, a small lunette, and a large lunette, and after six months I still can't wear the large lunette without it leaking. I'm very happy with my other cups, we're good friends. But I bought the large lunette because my IUD gives me really heavy periods for the middle two days, and quite frankly the enterance to my vagina gets tired of me poping cups in and out of it every hour and half, so I was hoping the large lunette would give me more time between when I need to empty it. I've been using cups for over six months now, so I know the usual tricks: spin it, try it in-side out, tug on it to seal it ect.
I'm just wondering what the reason is that a bigger cup won't seal well, when a smaller one will. So if anyone has any ideas, I'd love to hear them. I'm as happy as it gets with my other cups, I just want to know as much as I can about how they work.
