I have just purchased a type A Keeper and used it the last two days of my last period. I was wondering if anyone might be able to offer some advice on the stem? I have left about 5mm left of stem, as chopping it off entirely makes the three month return warranty void, but I am finding that it is rather uncomfortable - fine when I am sitting or stationary, but rubs a bit when I am in motion. I know that some people remove the stem entirely but am not sure if this will work for me or not. The stem sits just outside of my vagina, so it tends to poke me when I move. Can anyone advise about this?
