I've been using the diva cup (small) off and on for a while now, and finally feel like I can get it in place with little problems.

I make sure the cup pops open and tug on it lightly to make sure there is suction. I'm usually pretty satisfied with how easily I can do it now But even though it's seems like it's in place and just fine, it starts leaking before it's even halfway full.

I'm using my cup with a liner and two pairs of underwear 😠 what am I doing wrong?
