Who else struggles with a Diva Cup?!

I really want the Diva cup to work for me, however, most of the time I put it in, it puts a ton of pressure on my bladder. I am spending 15 minutes in the bathroom each time and still cannot get it in comfortably most times. It has so much pressure on my bladder I have to take it out to pee of I leave it in because I push and nothing comes out. Soon as I take the cup out, I pee for what feels like an eternity. Does anyone else have this issue or am I just doing it incorrectly?
