Dani,
I used them when I had my periods. Love them! It is messy at first, at least until you get use it. Then you'll wonder why you haven't heard of it before. Such a life saver, don't have to carry around big uncomfortable pads or Tampax with you. Maybe a panty liner, just in case, there is always the worry of that. But, I never had to use them either, cause I new when to empty the cup. Until you get use to it, you'll need panty liners/wipes with you. You'll get use to it very quickly.
Have a more active life!
Janie
