Please check that you have trimmed the stem to the correct length for you and ensure that you are aiming your Mooncup towards the small of your back. If you have the model B Mooncup and it continually moves around, or leaks, then you will need the model A, which is only 3mm bigger. If you find that the model A leaks then you can try pelvic floor exercises to strengthen the vaginal muscles which hold the Mooncup in place."
Has anyone with persistent leakage problems tried moving from a model A to a model B?
Next poll on leakage, methinks. I'd be interested to see if some makes of menstrual cup are more problematic than others.
