My funny Canadian friend Holly introduced me to this:
Diva Cup
things I like about it:
easy to insert
lasts 12 hours
you absolutely don't feel it
economical
more earth friendly than the other PMS options
small and discreet
things I don't like about it:
the name (the word diva makes my skin crawl)
Try it out, it's one of the best purchases I have ever made.
