12-HOUR LEAK PROTECTION
HOLDS 5+ SUPER TAMPONS
IN AND OUT IN A PINCH
MESS-FREE PERIOD SEX™
1. Pinch it. Wash your hands and pinch the disc in half. Once it's pinched, it's about the width of a tampon.
2. Insert and tuck. Angle it down and back toward your tailbone, push it as far back as it goes, then tuck the front rim up behind your pubic bone. Then forget about it for up to 12 hours.
3. Hook and remove. Hook a finger under the rim, pull slowly and keep it level to prevent any spillage. Pro tip: For a low-stress first removal, try taking your disc out while in the shower.

AMAZING PRODUCT
Living with PCOS is very difficult. My last period lasted for 11 days and I had to change my tampon every hour or less because I had such a heavy flow... I tried Flex. Best decision I have ever made! It's comfortable and I can still do whatever I want without worrying about it.

HEAVY BLEEDING
PERIMENOPAUSE
I was usually fine with just a regular tampon and pads, until I hit Perimenopause... I really still don't know how I would be able to hold employment at this stage without this disc.

PERIMENOPAUSE
LIFE CHANGER
I have the worst cramps ever and a very heavy flow... switching over to these flex discs was truly a life changer. Much less cramping, and no worries of over flooding super tampons. [...] Truly the best switch of my life. If you’re thinking about it, just go and do it.

PERIOD CRAMPS
HELPED MY CRAMPS
I have endometriosis and after I started using the discs, it actually HELPED my cramps! It's cleaner than tampons/pads/period underwear. Reduces risk for TTS. Can hold up to 5+ super tampons. Can be worn while sleeping, swimming and...... Sex. I'm never using anything else besides these. Thank you.

- KJKarlie J.Verified Buyer3 weeks agoRated 5 out of 5 starsNever using tampons again
I have been using Flex Discs going on 2 years now. I will absolutely never go back to tampons. I have had to use them when I am in a bind or start my period without being prepared and have had to get one from a friend, and I get irrationally mad every time.
I have a system down with my discs when I need to change them, and overall I feel so much more sanitary then when using tampons. They also work great when I am on my period during jiu jitsu, I never feel like I have to check whether or not I am bleeding through any of my gear during training.
I recommend Flex to ALL of my girlfriends, they really are life changing.
- CChloe4 weeks agoRated 5 out of 5 starsLife Changing
When I stopped using standard period products and switched over to a mensal cup, and didn't like the fit or fell.
Desperately, I then tried the disc, it was like a light switch flipped in my head. No dry tampon pulls, no wet pad "diaper rashes", just clean insertion, keeping me well maintained throughout anything my day has in store, PLUS a clean removal , truly making my periods slightly less dreadful to look forward to
I recommend it to literally every women who will let me talk about it.
I cant recommend it enough.
- AKAndrea K. P.Verified Reviewer4 weeks agoRated 5 out of 5 starsThanks to the founder!
Dear Lauren,
I wanted to personally thank you for your innovative approach to menstrual care! Your invention has truly changed lives and I personally thank you for transforming Gynecologic care in this country. My hope is that it will reach worldwide to women on all continents & your vision will translate internationally. I only wish this would’ve been available to me during my high school and collegiate years. I am now 52 and perimenopausal, but have enjoyed your products during my “transition” years.
I have recommended FLEX to several of my girlfriends whose daughters are starting their periods and they too love the products!
I would love to support your company if ever you want to extend any philanthropic pursuits in Africa or Asia to support our sisters “across the pond”.
Gratefully,
Andrea Parde M.D.

- LLiv1 month agoRated 5 out of 5 starsActually Does What It Claims!
I bought this product solely because it claims to work for mess-free period sex. My boyfriend and I were a little skeptical that it would stay in place and be comfortable. I’m happy to say it worked perfectly! It didn’t move out of place or feel weird at all and we tested it thoroughly. I didn’t even need to think or worry about it! I am about to buy the reusable one because for the price it is definitely worth it and I also try to be as sustainable as I can with period products.
- CGCaitlin G.1 month agoRated 5 out of 5 starsI wore white pants on my second day
I love flex discs!!! I am someone who has a small pelvic floor and the cup is just too much for me. I have tried the discs and I am NEVER going back to tampons!!!! I can leave them in for a long period of time without worrying about leaking. They are so comfortable and reduce my cramping and bloating. I don’t even realize I’m on my period anymore. Serious life savers.
Honest answers to your most common questions
-
Flex Disc currently comes in one size and was designed to fit a wide range of bodies. It sits in the vaginal fornix (just beneath your cervix) instead of in the canal, so it doesn't press on your vaginal walls the way a cup or tampon can. And the fornix just so happens to be the widest part of the vaginal canal. So if you’ve had trouble with a cup before, don’t be afraid of a disc based on how it looks. That said, Flex Disc does run on the larger side in terms of discs. If it's not right for your body, don’t give up on discs altogether. There may be another option in your drugstore aisle that works better.
-
Flex Disc shouldn’t leak as long as it’s inserted correctly, fully surrounding your cervix. When you’re learning, we recommend wearing a liner for the first couple of days. Most leaks come from a disc that isn't pushed all the way back, isn’t fully tucked behind your pubic bone, or from overflow on a heavy day. If it empties a little when you use the bathroom, that's normal: your pelvic floor relaxes and the disc can slip forward, letting a little fluid out into the toilet. Just tuck it back up with a clean finger when you’re done.
-
Removal can take some practice, but don’t worry: your disc can’t get lost! If it feels hard to reach, try removing in the shower when your body is more relaxed, changing positions (like a low squat or a leg up on the toilet), or using your pelvic floor muscles to gently bear down and push the disc forward. Then just hook a finger under the rim and pull. There's no suction seal to break. If you're stuck, our Flexperts can walk you through it.
-
Lots of Flex Disc users have IUDs, and the disc doesn't use suction to stay in place, which may reduce the risk of accidental IUD expulsion. Every IUD sits a little differently, though, so check with your doctor or Ob/Gyn before using any internally worn product. They'll know how your specific IUD is positioned.
-
Yes, but make sure to use a fresh disc before intercourse. Some people will see a little residual blood from your vaginal walls. As long as the disc is inserted correctly, it will be up and out of the way for sex, sitting beneath your cervix to catch any blood while leaving your vaginal canal clear. If your disc feels low at first or it causes any discomfort for you or your partner, you may just need more foreplay: your vaginal canal expands when you're aroused, and your disc will typically move farther back as that happens. If you continue to experience any discomfort, it’s best to stop, wait a bit, and remove your disc. If you use lube, make sure it’s water-based. After sex, wait 30 minutes to an hour before taking it out so your body can settle. Flex is not a contraceptive and doesn't protect against STIs. If you use condoms, friction with the disc can make them less effective, so use a backup method.
