1. What's the difference between FLEX Disc and FLEX Cup? Simply put: FLEX Disc is a menstrual disc and FLEX Cup is a menstrual cup.



A menstrual disc is a round, flexible ring with a catch that sits at the base of the cervix in a place called the vaginal fornix. A menstrual cup is a small flexible period collection device that sits in the vaginal canal and is typically tapered at the base.



Both the disc and the cup can be worn for up to 12 hours, but what you do once you take it out is another point of difference. The disc is disposable and single-use only, so you simply empty the contents and throw it away after a single use. With the cup, after emptying the contents, you clean it with soap and water and reinsert as directed.



Because of where the disc sits in the body, it can also be worn during penetrative sexual intercourse, the cup however must be removed before sexual intercourse.



Some people prefer the disc, some prefer the cup, and some like to use both depending on the day! Whether you choose single-use disposable discs or a reusable cup is up to you. We believe in the power of choice, which is why we offer the most innovative options in both categories.

2. Do they work with a heavy flow? The majority of our customers have heavy flows - including those with endometriosis and PCOS who swear by FLEX products.



FLEX Disc can hold up to three super tampons worth of menstrual fluid. It is also safe to wear for up to 12 hours. Another benefit of using FLEX Disc on a heavy flow day is that we have a trick for hands-free emptying so you don’t even have to remove your disc to achieve the full 12-hour wear!



FLEX Cup is also a great option for users with heavy flows. The Slim Fit holds the equivalent of 2 super tampons, while the Full Fit holds the same 3 super tampons’ worth of period blood. On heavier days, just like the disc, it may require more frequent emptying.

3. Can I use them with an IUD? There is a small risk of any internally worn menstrual product getting caught on your IUD - including tampons, menstrual discs, and cups.



If you use an IUD, you should be informed about your particular IUDs benefits and risks and consult with your physician.
