I currently have the small Ladycup and I have no problems with leaking or anything. Taking it out can be difficult because I can't fold it so it hurts like heck emptying it, which doesn't make the cup prospect seem very nice lol. It's also a little more difficult to go #2 with the cup in and I realize now that it may be pushing on something. Is there a slightly softer cup than the ladycup available? I definitely don't want anything bigger.
Edit, I'm considered the soft MeLuna because I've realized the Ladycups rim is too resistant right now so I can't fold it. Anyone have any experiences or tips for the MeLuna's? I would still use a size small..?
