I used something several years ago, I think it was called the Moon Cup or something like that. It was before I had any babies but it worked really well and saved me a bundle on pads/tampons. You just have to be comfortable with kinda getting up there, in a messy time of the month. Luckily my work bathroom was a single user bathroom, so I could dump out the contents and rinse it off in the sink too. I should really pick one up after baby #2. It's ridiculous how expensive pads are. They've got us by the ovaries :P
