Learn how menstrual discs work
Meet our discs
A menstrual disc is a comfortable, sustainable alternative to tampons and pads that sits in a different part of the vagina: the vaginal fornix. It’s the widest part of the vaginal canal, all the way at the back and just beneath the cervix.
Flex Disc, Flex Reusable Disc, and Flex Plant+ Disc all work the same way: They’re held in place by your pubic bone, leaving your vaginal canal totally unobstructed. This means you can enjoy all the period sex—without stained sheets—your heart desires. 😉
Insertion, mid-wear, and removal
MENSTRUAL DISC INSERTION
STEP 1: PINCH YOUR DISC
First, wash your hands. Pinch the disc in half (it may look big, but once pinched it’s the same width as a tampon).
If you’re using Flex Reusable Disc, wash your disc before inserting. Make sure you’re pinching it around the insertion notch, so that the notch creates a narrow point at one end. There is no notch on Flex Disc or Flex Plant+ Disc.
STEP 2: GET READY TO INSERT
Take a breath and relax! Get into a comfortable position—you can try sitting on the toilet, squatting with your legs spread, or standing with one leg up.
STEP 3: INSERT THE DISC
Insert the pinched disc into the vagina, angling it down and back towards your tailbone. Use your thumb or forefinger to push it as far back as it will comfortably go. Then, tuck the front rim of the disc up behind your pubic bone.
STEP 4: 12-HOUR WEAR
All-day wear means you can do whatever you want—even sleep in. Wear Flex Disc, Plant+ Disc, or Reusable Disc for up to 12 hours at a time.
MENSTRUAL DISC REMOVAL
STEP 5: READY TO REMOVE YOUR
First, wash your hands. Take a deep breath (it’ll help your pelvic floor muscles relax). Then, take a seat, squat, or stand with a leg up. Slide your finger into your vagina until you feel the front edge of the disc. Hook your finger under the rim and slowly pull the disc out, keeping it parallel to the floor as you remove it.
Flexpert Pro Tip: Removing the disc in the shower is a game-changer. It’s super easy and washes any messiness away (along with your worries).
STEP 6: GOOD TO GO
USING FLEX DISC OR FLEX PLANT+ DISC?
Empty the contents of the disc into the toilet. Place your used disc back in its wrapper, if you’ve held onto it, use a Flex Eco Disposal Pouch, or just wrap it in some TP. Then, simply toss it in the trash. Ta-da! You’re done.
USING FLEX REUSABLE DISC?
Empty the contents into the toilet (or rinse in the shower) and wash Flex Reusable Disc. First, rinse with cold water to prevent trapping odor. Then, massage with a mild soap or cleanser like Flex Foaming Cup Wash. Rinse again, this time with warm water. Reinsert or store your Reusable Disc in its pouch until next time.
Menstrual disc pro-tips
The thumb trick
Once you've inserted your disc into the vaginal canal and you can no longer keep it pinched, place your thumb on the rim and push it back and down until it's just behind the pubic bone. You can then use your index finger to prop the rim up behind the pubic bone to keep the disc in place.
Bear down for easier removal
To pop the rim of your period disc out from behind your pubic bone, it can be helpful to engage your pelvic floor muscles. To do so, just bear down as if you were trying to poop. You don’t have to push crazy hard, just a little bit—and try to do so while you have a finger inserted so you can get ready to hook your disc and pull it out.
Explore different positions
Because every body is different, it's important to find the position that feels best for you when inserting your disc. Some options include: sitting on the toilet, standing with a leg propped up, squatting toward the floor, laying on your side, or even getting into tabletop pose.
