I originally got a Soft MeLuna medium. I have only used it a few times, but in that time, I've had leakage issues. The first try I found out was because it was unfolded, but it was still flat. Since then, though, I've still had issue. I asked some questions on here and contacted the Meluna staff for any advice. I received some (thank you), and Meluna said it sounded like I got the wrong cup for my body. I now have a Klassic Meluna Mini medium. It leaks, and I mean a lot. I have had to wear a full pad because of how much it leaks. I switched back to the soft cup, but it is still leaking as well, though not nearly as much as the Mini. Both are comfortable. The Mini doesn't seem to find a "sweet spot" where it stays, unlike the Soft, and I can pretty much just pull it out without issue. In both cases, the cup is fully unfolded, not dented in, I hear the whoosh of air and it is no longer flat...I spin it, pull it, Kegel it. I'm just not sure what else to do. With the Mini I tried putting it lower; it leaked. Then I tried tucking it up around my cervix, but it doesn't seem to be able to do that. Instead, it seems to sit only half-covering the cervix instead of sitting around it. I would love to get the Mini to work because it has a higher capacity, which I need.
