Insert & remove

Can I do this?

Your first cycle with a disc is a learning curve. Almost everyone's is. Here is the whole thing including taking it out.

1. PINCH

1. PINCH

Flex Reusable Disc may look big but it’s actually smaller than a tampon when inserted. Start by washing your hands and pinch it in half.

2. INSERT

2. INSERT

Use a clean finger to push the disc back and down toward the cervix, then tuck it up and behind the pubic bone.

3. WEAR

3. WEAR

Once the disc is in place, you should be comfortable and unable to feel it. You can wear it safely for up to 12 hours.

4. REMOVE

4. REMOVE

To remove, hook a clean finger under the rim of the disc and pull straight out. Keep it parallel to the floor to avoid spillage.

Why you’ll love Flex Reusable Disc

Will it fit?

Flex Reusable Disc was designed to fit most vaginas. When you pinch the disc in half to insert, it’s about the same size as a tampon. It sits comfortably in the vaginal fornix—at the back of the vaginal canal, just beneath the cervix—and collects, rather than absorbs, your period.

What first-timers ask most

  • Yes! You can swim, sleep in, go for a run, and even have period sex while wearing Flex Reusable Disc without having to worry about leaks or irritation. Since the disc collects your period blood rather than absorbing it, it’s ultra-comfortable both on land and underwater. Say goodbye to that waterlogged feeling and ditch tampons for good with Flex Reusable Disc.

  • We get it—it’s hard to imagine. How can you wear a menstrual disc and have sex at the same time?! But you totally can, and it’s one of our favorite benefits of using a disc. Here's some more detail: 

    The vagina expands and elongates during arousal and intercourse. This allows a menstrual disc to be worn during sexual activities without it getting in the way or coming out. It already sits at the back of the vaginal canal, in the fornix, and it should move well out of the way when you’re turned on and once penetration takes place. 

    In other words, a menstrual disc should be comfortable for both you and your partner during period sex—and that includes sex of all kinds (from penetrative to oral). There is a chance that one of you may notice the rim, but there shouldn’t be any pain or irritation. How much you or your partner may feel the disc depends on your position, your anatomy, and your partner’s anatomy. 

    Warning: You may have stronger orgasms while wearing a disc! This is because it gently rubs on the cervix during intercourse for additional stimulation. 😉

    FYI: Only menstrual discs (Flex Disc, Flex Plant+ Disc, or Flex Reusable Disc) can be worn during penetrative sex. If you’re using a menstrual cup like Flex Cup, you’ll need to remove it beforehand. 

  • When inserted properly, you shouldn't be able to feel a menstrual disc at all (with your vagina). Over 97% of users surveyed did not feel Flex Disc while using it. 

    In other words, once you’re going about your day, you shouldn’t be able to feel the disc inside of you. This includes Flex Disc, Flex Plant+ Disc, and Flex Reusable Disc

    If you’re experiencing any sensation or discomfort, it’s likely caused by the disc not being inserted quite right.

    The first thing we suggest is removing your disc and taking a moment to locate your cervix. You can try to feel your cervix by inserting a clean finger into the vaginal canal and feeling around until you notice a firm spot that feels like a tiny donut (about the firmness of the tip of your nose). It may also feel like puckered lips. 😗​ If you can’t reach your cervix—this is normal!—bear down gently with your pelvic floor to bring it closer to you. 

    Once you’ve located your cervix, you’ll have a better idea of where your disc needs to sit and how far back it will need to be inserted. 

    To make insertion easier, try doing so from a seated or squatting position to move your cervix closer to the vaginal opening. Remember: You want to aim the rim of the disc that enters your body first down and back, towards your tailbone. Aim for under your cervix! Then, you’ll use your finger to pull the front rim (the side that enters your body last) straight up towards your belly button, tucking it securely behind your pubic bone. Don’t be afraid to get in there!

    You can even use your pelvic floor muscles during insertion to “pull” the disc into place once you’ve pushed it down and back as far as it will go by doing a kegel. This is basically just an inward pulling motion with your pelvic floor—the opposite of bearing down. 

    When you’re done inserting, the disc should be sitting at an angle and completely surrounding your cervix. Think back rim down towards the floor, front rim up towards your belly button. 

    Everyone's anatomy is different, so don’t be surprised if it takes you a couple of cycles to get the hang of using a disc!

  • First, don’t panic! A menstrual disc (or cup, or tampon, or any period product, for that matter) cannot get “lost” inside your body. Your vagina is shaped like a cul-de-sac, thanks to your cervix. 

    In most cases, all it takes is a little relaxation and some command over your pelvic floor muscles to get literally anything that might happen to be stuck inside your vagina back out of your body. 

    If you’re having a hard time removing your menstrual disc, including Flex Disc, Flex Plant+ Disc, or Flex Reusable Disc, please reach out to our team of Flexperts at (800) 931-0882 so they can help. You can text! Hours are 5:00 a.m. to 7:00 p.m. PST every day of the week.

    In the meantime, here are some additional tips and tricks to help with disc removal:

    First, take a few deep breaths. Try using a box breathing technique to calm your nervous system and help you relax your pelvic floor muscles. Breathe in for 4 seconds, hold for 4 seconds, out for 4 seconds, hold for 4 seconds, and repeat. 

    If you’ve just had period sex with a disc, make sure you wait at least 15 minutes to give your body a chance to “cool off” and your cervix to move back to its normal position. During sex, arousal can make the vaginal canal twice as long as normal! This moves your cervix further back in your body, which can make it tough to reach your disc if you try to remove it right away.

    Insert a clean finger into the vaginal canal and, at the same time, push down (or think down and forward, like ejecting a DVD) with your pelvic floor muscles. You can deepen the push by saying “moo” out loud at the same time—it may sound silly, but it really works. 

    When you bear down, you should feel the rim of your disc move further down the vaginal canal and pop out from behind your pubic bone. Make sure your finger is already inserted while you do this! When the disc is easily within reach, hook your finger under the rim and slowly pull it out, keeping it parallel to the floor to avoid spills. If you feel like your finger is slipping out from under the rim, try gently bracing against one side of the vaginal wall. 

    Still not working? Try a different body position: Squatting low (bum-to-floor) with your feet wider than hip-distance can make it easier to pop the disc out from behind the pubic bone. Doing this while in the shower is a great way to stay relaxed and prevent any messiness. Alternatively, try laying on your bed, sitting on the toilet with feet propped up on a stool, standing with one leg propped up, or even tabletop pose. 

    If you're still struggling with removing your disc, please take 30 minutes to an hour to relax your body, and come back to removing your disc once you feel calm and ready. Do not use any foreign objects to remove your disc as this can cause damage to your vaginal canal. Contact us whenever you need help or, if it’s after-hours and you’re still stuck, try asking a partner or friend for help. You can also always reach out to a healthcare provider or Ob/Gyn!

    Life changing

    I'm almost angry that I only discovered this menstrual disc in my late 30s. God, my life would've been so much easier if I had this 20 years ago. I wouldn't have had that mortifying experience where I bled all over myself in an airport lounge without realizing it, didn't have time to buy a change of clothes, had to sprint to my gate clutching a purse strategically, and then sit an entire flight with my legs crossed. TMI, but the point is: this thing will change your life.

    There's a bit of a learning curve, but once you get past that, it's easy breezy. Also, a heads up: if you have vasovagal syncope, like I do, be aware that the first couple of times might trigger a fainting spell. So be ready to lie down on your bathroom floor to stop it. That sounds dramatic, but after the first couple of times, it'll likely stop registering as a trigger (like it did for me).

    Wow.

    I can’t believe that I am alive at the same time that this exists. I wish every woman throughout all of history could experience this method of dealing with their period. The way that this has made my life so much easier on the worst time of the month makes me feel so grateful. You think I’m being dramatic?! Try it yourself. This s**t is life changing.

    Hello Full Night Sleep!

    I love wearing mine at night so I don't need to wake up at 2am to change a tampon. I already get extra tired on my period and disturbed sleep made it worse. The reusable cups has been so nice for that.

    This saved me from dealing with a heavy flow

    My heavy flow days are heaaaavy. Like soaking thru a tampon every 90 mins to 2 hrs. I have to have a pad on just to make sure that it catches the overflow. Flex changed my life. I love the self emptying tech with the silicone disc. I love how comfortable it is, I forget that I have my period and can go about my day. I still use a pad on my heavy days to make sure I dont have accidents, but this little thing lasts for at least 8-9 hrs for me and then I can go pee and empty it out a little. Phew! Don't ever stop making this!
