So, I've had my Diva cup for approximately 4 years now.
The first 3 days, my cervix is really low and the diva cup works great never leaking. However, after that I've never been able to master it and I would get slight leaks.
It never used to be much of an issue because my periods were light enough and the leaks were always very minor. Nothing black underwear didn't fix. Now I have a IUD its causing a lot of issues. Not sure if my cervix is sitting differently, or simply the heavier periods but its been way worse.

Basically my cervix is a lot higher and i feel like my vagina is shaped like an upside down vase, so that there's a lot more room for the diva cup to move a round an start to leak. I check to be sure my cervix is "in" the cup every time, and always about 2 hours later, its out of the cup and leaking.

I really want my IUD and Diva cup to get along, and I do not want to go back to pads/ tampons. Please help.

I'm 20, never had kids, and using the small Diva Cup. And I already kegal it into place, it still seems to move.
