diva cup

So I started using the diva cup about two periods ago, it was a little weird at first and sometimes still is. It wasn't something I originally heard of, but given my experience I don't want to go back to tampons. I'm super irregular, and never really know if I'm just spitting or actually starting. Using a tampon dried me out of I was wrong, not to mention painfully removing one at the end only to discover I thought I was still going and I wasn't. With this I don't have that problem. When I think I'm starting it I use it and if I'm wrong, I pull an empty piece of silicone out, if I'm right, I don't have a leak the entire time. What are your thoughts on this less known method?
