I have to say I absolutely love my diva cup. I've been using it for about 4 years. The first 6 months or so had a learning curve for me. I would occasionally have leaks, but I often did with other methods, too. I have found that on really heavy flow days, I have to empty it 2 or 3 times a day, and actually I get a slight cramping feeling when my cup is near maximum capacity. I don't know how that is, but it is consistent.

Given the conversations about diaphragms, I will say I also use one of them for birth control. Yes, they actually still make those things. And I really like it. I don't think I EVER would have considered it if I hadn't gotten comfortable with my diva cup first, but I've used the diaphragm for about 3 years or so. I'm firmly against hormones and it works for me.
