1) I just need practice, especially with differentiating between true leakage and residual goop.
2) I need a stiffer or possibly larger cup. I have had two kids vaginally, but I do not feel like my pelvic floor muscles are particularly weak and, thus, in need of a soft cup. I bought the soft originally because it seemed less daunting. I'm over that now.
I am currently trying different things, like which way the fold faces, different folds, etc. I have had no issues getting the cup to open, and it seems like it is sealed well. It pops open, I kegel it into place, I run my finger around it, and there are no dents to suggest it is not fully open. I remembered reading before about people having to angle their cup a certain way due to a tilted cervix, so today I checked and found out that my cervix is pointed toward the back. I'm not sure if that is just the normal tilt since the vagina is actually at an angle or if it is actually tilted. In any case, I tried positioning my cup toward the cervix, but it didn't work; there is no room to wiggle it that way. It will tilt (very easily) to the right or the left, but it's very sandwiched as far as front and back go.
Even with the frustrating "leak" right now, I have to say how awesome it is to not be in fear of what surprises standing up after sitting for a long time, or bending over might lead to!
