got my first Diva Cup last week


so i got those fancy new diva cup things - I say new because, well, I'm a pads for life kinda gurl- anywho, anyone else use them? pros, cons, tips for first time user? worried about night leakage, especially in the beginning while im still trying to learn the right fitting technique, will i feel it when I walk? am I gonna look like a penguin when I walk? halp!
