I notice the smaller lunette says it's for teens, but the specs for it seem to be closer to the smaller divacup. I currently use the smaller DC (my first cup and first period with it ) but it's too long and keeps poking out stem's all gone, the actual cup is poking out - and it's annoying as heck. I'm thinking of getting a shorter cup and thought I'd try the Lunette. I'm 26, not a virgin, but never pregnant. Should I get the larger Lunette or the smaller one?
