I am 25 and have not given birth. I am a size B mooncup UK user a few months now but I have had leakage problems since the beginning, especially during my heavy days. I am sure I am positioning the Mooncup properly, I always make sure it sits low and rotate it after I insert it. I also tried to stretch the holes following the advice of a Mooncup advisor. I eventually tried switching to size A but nothing changed, the leakage is exactly the same.
I read that cervix position is an important factor and decided to measure mine. On my second day (heaviest flow) my cervix is 8cm high. Could it be that the combination of my high cervix with a short cup like Mooncup results in the cup being "sucked up"? When I remove the cup I always feel it is higher than I initially positioned it.
Could a Diva cup (I heard it's the longest available in the market) be the solution?
I would really appreciate any feedback, I really want to keep using a menstrual cup and hate the idea of going back to disposables!
