Diva Cup Leaking??

Ash

Help!! I'm on my third cycle using my diva cup, it seems to keep leaking no matter what I do?? I had no problems with it my first period but the second cycle I used it it seemed to leak but when I removed it, it would be almost empty. I can rotate it when it's inside and feel that it's open and suctioned but it's still leaking. Any tips or tricks? Please help!! 😩😩

Edit: I'm using the small sized Diva Cup as I'm 19 and have not given birth to a child.
