Can I use a cup with a heavy period?

The menstrual cup works really well for those with a heavy period, or Menorrhagia, since it can contain 3 times more than a super tampon. In the beginning while you're getting to know your cup and flow, we recommend you empty the cup more frequently to see how quickly it fills up. If you have a heavier flow, you might have to empty your cup more often than twice a day.
