My first cup is the Lily cup. There are many things I love about it; it's easy to insert and remove, it's soft and doesn't push on my bladder. The issue I'm having is that it only stays in place on the second day of my period, which is the heaviest day so that's awesome, but the other days it's like I can't get it in far enough and it feels like it's coming out. Does anybody else use more than one cup based on their flow rate? Can my cervix change height that much during my period? The day I really need it, it works great but the rest of the time, I'm not happy about. I'm considering getting th Lily Cup Compact for the lighter days, just looking for some insight, thank you in advance.
