    Bachelorette party on the beach with no bathroom approved

    Omg this disc saved my life on a bachelorette party on the beach. No leaks. Another girl that was there that was wearing a tampon had a major leak I told her about the flex disc. I cannot wear anything inside my vaginal canal I always feel it and it’s so uncomfortable. You cannot feel this at all and I feel fresh and clean because I’m not sitting in a sopping wet pad or period underwear. I do use period underwear with the disc as a backup only but I hardly ever have any leaks if I do they are very slight. The self empty part of this is the best thing ever and allows me to empty without having to remove it. There is a learning curve but I got the hang of it after 2-3 cycles. Never going back to disposable period products!

    SAVED MY LIFE FROM THE ENDOMETRIOSIS SUPER HEAVEY FLOW

    I have used tampons plus backup pads for most of my life due to my super heavy flow and horrible debilitating periods plus endometriosis. When I first discovered Flex discs I was skeptical that it would be any better than what I was used to. I WAS WRONG! These things are a game changer: I can swim, I can work long shifts, I can do whatever I want while wearing one and the only thing that happens when my flow is at its heaviest is a bit of auto-dumping when I go to the bathroom. If the disc becomes too full, the seal is broken by the force of the pelvic muscles during urination. However, when that happens all I have to do is (with clean hands) push it back into place. They have given me back my freedom. Also, I have never given birth (as is recommended before you use certain kinds or sizes menstrual cups) and these are very easy for me to insert.

    Unfortunately, using flex discs did not lessen the severity of my cramps, but that was not the reason I switched to them and I wasn’t too disappointed because I know my cramps and period pain are extremely severe. So that wasn't a dealbreaker.

    A word of advise: if you have to poop, wash your hands before going to the toilet and remove the disc FIRST, empty your bowels, wash your hands again THOROUGHLY, and then insert a new disc. In my personal experience, it’s very difficult to insert the disc when you are about to poop because there’s less space in the vagina when the rectum is full.

    The only people I wouldn’t recommend these…

    10/10 love

    I got the disposable ones because I wasn’t sure about a reuseable flex disc and these are great, weird to insert at first but once you get used to it it’s a life changer. My cramps have been nonexistent and my periods are actually shorter! It’s great to not have a tampon string or have to worry about smell. I will say if you don’t change after 12 hours or if you have very heavy flow there is a risk of leakage but it depends on each person, I only had leaks the first period I tried this

    What??? How did I live without this? 😭💖

    Decided to give this one a try after my GP told me I needed to avoid period cups (I have a copper IUD, which means suuuuper heavy periods). Got it in the post yesterday, the packaging is gorgeous, and after watching videos of the founder of Flex talk about it, it’s so obvious that a lot of hard work and clever engineering has gone into creating this genius little life-saver.

    Super easy to insert, and honestly can’t even feel it’s there at all. Huge bonus: sleeping with the disc in! I’m for sure throwing away my dedicated, blood-stained period sheets as I won’t be needing them anymore 🤣

Frequently Asked Questions

Flex Reusable Disc is a body-safe and sustainable menstrual disc that provides all-day comfort and a high capacity, holding as much as 6+ super tampons-worth (70 mL) of fluid. It was thoughtfully engineered to be as easy to insert and remove as our best-selling disposable Flex Disc—but it’s 100% reusable and lasts for years. 

Flex Reusable Disc features two new technologies for easy insertion and removal: Made with dual silicone construction, the disc has an ultra-soft, thin catch and a sturdy rim for non-slip removal, while its patented insertion notch creates a narrow point at one end when the disc is pinched for easier placement. 

Like Flex Disc, the Reusable Disc is worn in the vaginal fornix. This means the vaginal canal is left unobstructed, so you can enjoy all the mess-free period sex™ your heart desires. Sleep in, swim, go for a run, live your life: Flex Reusable Disc provides 12 hours of uninterrupted leak protection and comfortable wear. You might even forget you’re on your period.Flex Reusable Disc: Great for your wallet. Even better for the planet.

The lifespan of the Flex Reusable Disc varies depending on cleaning and care, but it can last for years. As a general rule of thumb, we recommend replacing your disc every two to three years, or as soon as it begins to show any signs of deterioration (such as powder or film, severe discoloration, persistent odor, etc). Refer to our Reusable Disc Cleaning Instructions to learn how to care for your silicone disc and extend its lifespan. 

As a reminder, do not use Flex Reusable Disc if you have a yeast or bacterial infection. Resume use only once the infection has completely cleared. If Flex Reusable Disc was inserted during a yeast or bacterial infection, remove it immediately and dispose of it in the trash.

The majority of Flex Disc users have heavy flows! We’ve heard from tons of customers with especially heavy periods who swear by Flex Disc, thanks to its higher capacity and 12-hour (read: all day) wear. The disc can hold up to 60 mL of fluid. That’s as much as 5+ super tampons!

Worried about leaks? Don’t stress. When inserted correctly, Flex Disc shouldn’t leak. You can even extend your wear time on your heaviest days by taking advantage of the disc’s hands-free emptying feature: Just bear down gently with your pelvic floor muscles when using the bathroom. This will shift the position of the disc so that it allows a little fluid out into the toilet. When done, simply use a clean finger to tuck your disc back into place behind your pubic bone. 

Have Qs? Feel free to reach out to our Flexperts: Call 800-931-0882 or email help@flexfits.com.

First, wash your hands. Find a position to insert your disc: Some sit over the toilet, some stand with a leg elevated, some insert in a full squat. Play around until you find a position that works best for you!

Pinch the disc in half and begin inserting it into the vaginal canal, making sure you are pushing the edge that goes in first down and back towards your tailbone so that it sits at an angle and fully covers the cervix. Down and back is key! Then, tuck the front rim above and behind your pubic bone. Make sure it's pushed past the pubic bone as far as it can go.

You shouldn't be able to feel the disc. If you can still feel the disc internally, meaning with your vagina, just take it out and try it again. When you’re first starting out, know that it’s normal for it to take a few tries before you’ve mastered insertion! Learn more here.
