Hi again. I have been using a large Lunette since 2007. It had quite the learning curve, but I think I've figured it out though I'm a little disappointed that I can't use it without having to wear backup (pad or pantyliner). I wear it inside out and I removed most of the stem so that it could fit. On my period I've noticed that my cervix tends to be low enough that with a little reach I can touch it. I checked the size and length chart and it seems that I would be best with the large Iris cup or the small Green Donna cup. However, their capacities are lower than that of my Lunette. Should I a. Go with the Iris b. go with Green Donna or c. Stick with my Lunette and wait until a better cup comes along ? I'm surprised there hasn't been a company that will custom size a menstrual cup for you.
