I agree about the pills that can stop periods. And I'd recommend Kegel exercises to improve muscle control that can help with leaking.
I remember watching the videos and checking out the website regarding the period panties. Was a quick article that came out earlier this year regarding women entreprenuers. I'm personally not keen because what happens when I need to completely change out of my panties in the middle of the day at work? Had also seen a review when the white jeans test was tried.
