Questions & Answers
1. How much can it hold?

FLEX can hold up to 6 teaspoons of fluid (or the equivalent of five tampons). The average woman menstruates about 3 teaspoons in 24 hours. FLEX must be changed every 12 hours, so the average woman will have only 1.5 teaspoons of fluid inside.

2. Does it work with a heavy flow?

Yes! When placed properly, FLEX should not leak or overflow. Because FLEX can hold up to 5 tampons worth of fluid, some of our customers with heavy periods say that FLEX is the only product that really works for them.

3. Is this a menstrual cup?

We love this question. FLEX is not a menstrual cup, it's a menstrual disc. They are completely different products, the only similarity being that they both collect rather than absorb menses like a tampon. FLEX is disposable, which means you just remove and throw it away after using. Menstrual cups, on the other hand, must be emptied and rinsed because they are reusable and typically have to be boiled every month to disinfect.

The other big difference is that a menstrual cup sits in the vaginal canal, while FLEX sits in the widest part of the vagina called the fornix. This is why you can have sex with FLEX but not a menstrual cup, and why some people that had difficulty with the cup find FLEX more comfortable.

4. Does removing it get messy?

The short answer is that yes, for some people it can get a little messy, though most customers find that it's not nearly as messy as they expected. That's because the average woman will only have 1.5 teaspoons of fluid inside of FLEX at the time of removal, and since FLEX can hold up to 6 teaspoons, the menses will usually just stay in the catch as long as you're pulling FLEX out horizontally.

Most women remove FLEX in the shower since you can wear FLEX for 12 hours (simply insert FLEX during your morning routine and then remove in the comfort of your home 12 hours later).

5. Can I use it with an IUD?

Yes, FLEX is safe to use with an IUD and many of our customers do so. If you use an IUD, you should be informed about your particular IUDs benefits and risks and consult with your physician.

Try FLEX with some liners at first.

Sometimes you just feel better with a little backup. FLEX plus liners would be a great combination for you while you transition to FLEX to help guard against leaks until you get the hang of positioning FLEX.
