I have some major issues with my Diva cup and am not feeling the craze just yet. I put it in and it feels like it is high enough without the tip out or anything, but about five minutes later of walking around and the tip is totally sticking out and jabbing me. This happens throughout the day. If I sit, soon after rising it is fine, but about five minutes after walking it is jabbing me again. I feel inside and it feels open. Why is it slipping? Any suggestions on how to make it stop? I have read about it riding up, but this is going south!
