I just got a Lena cup and this is my second cycle using it. I'm 25, no kids and I have a high cervix, almost my whole middle finger goes in until it hits my cervix. So when I put my cup in I use all the advice I see, I pop it open right when it gets passed my pelvic bone and then slide it up give it a twist and it suctions. I run my finger around it and it's fully open and my cervix is inside.
BUT when I sit or move around too much, sneeze,I feel air get it and the seal breaks and I get major leakage shortly after inserting. Or when i sleep I will wake up in the middle of the night with leakage. I have a medium to heavy flow but my cup usually is only 1/3 full.
Is my cup too firm or not firm enough possibly? Are my muscles too strong or too weak? I have a full stem because it rides up far, could that be causing it to leak? I'm just not sure. I feel like I insert it perfectly. It's hard to continue use when I work everyday and need something reliable. But I won't give up just yet!
Any help is greatly appreciated!
