    I wish more girlies knew these EXIST!

    I absolutely love this! It feels like I'm wearing nothing at all, and my cramps are gone! It does take a little time to get used to, but you won't regret it afterward. Even intimacy while using it is just as amazing! I've worn it for almost ten hours, and it held up like a champ! It does create quite a mess when you dispose of it, but it's worth it no matter what. I wish I had found these earlier, but it's better to try them now than not at all!

    Wow

    The past couple months tampons started causing me a ton of itching and discomfort. I finally got desperate enough to try these despite being scared and a little weirded out by them. Not only will I never go back, but I also plan to buy the reusable disc, which I NEVER thought I would say. You truly can't tell these are in, and they work so much better than tampons. They are easier to put in than a tampon for me (I always used the tampons without applicators so it was a struggle getting it in the right place) and are so much more comfortable. I love that it's something I only have to think about right when I wake up and before I go to bed. Getting them out takes a little more effort than pulling a string, but I've had no issues. I never write reviews but I've been raving about these to all of my friends so I felt like I owed it to this product to share here too.

    LOVE LOVE LOVE

    The disc is the greatest thing ever created for periods. I used tampons regularly but had extremely heavy periods to the point where I was bleeding through super plus tampons in 2 hours, which prompted me to look for different alternatives. I tried menstrual cups and they were really difficult for me to insert. The disc (both disposable and reusable) is so easy to insert and genuinely does ease my cramps (how?!). The first couple of days of my period, I wear a tiny pad with it to supplement for mild leakage, but in comparison to the blow out of tampons I was experiencing, this is AMAZING. I seriously only experience small amounts of leakage during my first couple days (even with leaving it in for 12 hours at a time) and then the rest of my period is as if there isn't one. I would recommend this to anyone and have been telling every one of my friends to get it!

    It’s true. It works.

    As one who relies heavily on reviews I felt obligated to write my honest review. It took me two cycles to get this thing. You have to have patience, watch the video and keep trying. Once you figure the placement out you are golden and it will truly change your life. It’s true, cramps dissipate. I am 40 and I have suffered from cramps my entire life. I do not have cramps when I use the disc. There’s zero odor. I have had sex; although it weirds my husband out… it’s possible and if you’re desperate, it can absolutely be done. I cannot use one on Day 1 because my period is so heavy after two kids… I have tried many times and I still leak. I use a tampon the first day and disc every day after that— aside from dumb perimenopausal side effects (ugh) it’s like you are not even on your period. I’ll be a customer for the rest of my life. Give it a try. It’s worth it!!

    This thing changed my life!!!

    This thing makes me feel like I’m taking my power back and “winning” against my period. Way easier to use than expected, no discomfort whatsoever. Game changer for period sex. I cannot recommend this enough!!!! Never going back to any other period products.

Frequently Asked Questions

All Flex menstrual discs, including Flex Disc, Flex Plant+ Disc, and Flex Reusable Disc, can be safely worn for a maximum of 12 hours. 

Flex Disc and Flex Plant+ Disc are single-use products and cannot be washed and reworn. After 12 hours, dispose of your Flex Disc or Plant+ Disc and insert a new one.

Flex Reusable Disc, on the other hand, is meant to be washed and re-worn. Make sure to empty and clean your Reusable Disc at least every 12 hours (using warm water and a mild soap or cleanser) before reinserting. 

Menstrual discs, including all Flex products, are regulated by the FDA. They are approved for a maximum of 12 hours of continuous wear. Please use as directed. 

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.
