How do I insert and remove a menstrual disc?

If you’re a first-time menstrual disc user, don’t forget to reference the Instructions for Use enclosed in your disc’s packaging! For more detailed information, including video, head over to our complete “How to use a disc” page

Just need a quick refresher on disc insertion and removal? Here’s an abbreviated version: 

How to insert a menstrual disc:

  1. Wash your hands. Always wash your hands before insertion and removal. If you’re using Flex Reusable Disc, wash your disc, too, with warm water and a mild cleanser. 

  2. 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!

  3. 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! If you’re using Flex Reusable Disc, insert the disc notch-side-first

  4. Tuck the rim above and behind your pubic bone. Make sure it's pushed past the pubic bone as far as it can go. Another way to think about it: You want to bring the front rim of the disc up towards your belly button, so the front of the disc is angled higher than the back. 

  5. 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!

How to remove a menstrual disc:

  1. Relax. Making sure your muscles aren't tense will help you remove your menstrual disc swiftly and comfortably. So take a couple of deep breaths. You got this!

  2. While sitting over the toilet or standing in the shower, bear down gently on your pelvic floor. The sensation will be similar to that of pooping (don't worry, you won't actually poop). This will help pop the disc out from behind the pubic bone, making it easier for you to reach. Another way to think about engaging your pelvic floor is to imagine you’re hitting the “eject” button for your vagina and push your disc forward

  3. With a clean finger, hook the rim of the disc in a "come hither" motion and pull it out gently. Be sure to keep your disc horizontal (parallel to the floor) to prevent any spillage.

  4. Empty the contents of the disc into the toilet or down the shower drain. If you’re using Flex Disc or Flex Plant+ Disc, dispose of the used disc in the trash. If you’re using Flex Reusable Disc, rinse with cold water and then clean thoroughly with warm water and a mild soap or cleanser (like Flex Foaming Cleanser), then air dry and store in its pouch until next time. 

Know that it’s normal for it to take a couple of cycles before you’ve mastered disc insertion and removal! Every body is different. You might even find that the position of your cervix—which changes almost daily—impacts your insertion angle. The more comfortable you get with your body and with the disc, the easier it will be.

How long can I wear a menstrual disc?

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 reworn. 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. 

Will Flex Disc work for a heavy period?

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.

Can I really use a menstrual disc during sex?

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.
