So far I've had about half of a cycle with the Diva cup. I was wondering about backup pads. What strength do you need? I recently bought some Luna pads. I have never used cloth pads, but I figured they would save money in the long run, not to mention the environment. The pads seemed thinner than I thought they would be. Do you think that they will be enough to prevent staining my clothes? Does anyone else use cloth backup pads?
