The majority of our users have heavy flows. We've heard from tons of users with endometriosis and PCOS who swear by FLEX disc. The discs can hold up to 6 teaspoons of fluid (or the equivalent of three super tampons). The average menstruating human bleeds about 3 teaspoons in 24 hours.
We have plenty of tips and tricks to ensure it doesn’t leak no matter how heavy your flow is. We have a hands-free emptying article to show you how to get the most out of each disc.
If you’re trying your disc for the first time and are concerned about it getting too full, we recommend trying it out on a lighter day while in the comfort of your own home so you can get a sense of how much is in it after 12 hours. From there, you can adjust how frequently you need to change it based on your own flow. We also suggest wearing a pad or liner during your first cycle with FLEX should you have any issues with insertion.
You can also always check our other articles for insertion herp or reach out to us at firstname.lastname@example.org for additional help.
