Well I tried it on my last day of my period so it was very light.
Was a bit difficult to hold it ina punch down fold. Once inserted I lost my grip a few tims and it poped open. So I just inserted it quickly LOL it poped open and I got the sinking feeling but no cramps at all. I guess the rim being a bit more stiffer than the LC small I felt the cup in place but after about an hour or two forgot it was there.
Seems that the medium meluna holds a tad pit more than the lady cup. In the 8 hours I wore the me luna it was barely 1/4 full.
was not that bad at all. I pinched the bottom of the cup while holding the ring I felt the suction break and shimmied it out.
Im Glad I gave it another try and did cancel it out completly. Good to have as an emergency cup.
