I recently ordered a small LadyCup (actually LilacCup), and am thinking that I might like to get a large sized cup for heavier days. I've seen the size/capacity chart, but I don't know intuitively how much of a difference a few mL makes. A large LadyCup would probably be my first choice, and a large Lunette my second. Does the large Lunette hold significantly more than the large LadyCup; as in, would I realistically be emptying the Lunette less often? TIA!
