FLEX logo disc is easy to use

  •    Position
    • Wash your hands and take a deep breath. You've got this! You can sit over the toilet, stand with a leg up, or go in a full squat. Play around until you find a position that works best for you! FLEX disc may look big but it’s actually smaller than a tampon when you pinch it in half.

  •    Pinch
    • Pinch FLEX in half and begin inserting it into the vaginal canal by holding the disc pointing downwards in a vertical position.

  •    Insertion
    • Make sure you are pushing the edge that goes in first down toward the floor so that it sits at an vertical angle and fully covers the cervix. Down and back is key!

    Insert the pinched disc partway into your vaginal canal. Angle your thumb towards yourself pointing to the floor (think thumbs down). Now, use your thumb to push the tip of the rim the rest of the way in making sure you are pushing the edge that goes in first down toward the floor. Down and back is key! By doing this, you’ll have more control over the direction your disc is going.

  •    Placement
    • Tuck the rim (the front edge that goes in last) above 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 it at all if it’s in the right place.

  •    Wear it for up to 12 hours
    • Swim, work out, have sex, go to the bathroom, sleep, go along your day without having to worry about leaks or changes.

    If FLEX is leaking when you go to the bathroom, that’s normal. FLEX will push part way out when you relax your pelvic floor, but pops right back into place when you stand up. If it feels like it hasn't gone back into place, just use a clean finger and push it back up behind the pubic bone. You can also do a kegel afterwards.

  •    Removal
    • Always start with clean hands. Take a seat on the toilet or stand with one leg up and slide your finger up under the front edge of FLEX disc and pull straight down, keeping it parallel to the floor.

    While removing FLEX shouldn't be too messy to begin with, removing FLEX in the shower at the end (or beginning!) of your day can help prevent any mess at all. Go slow & steady is the way to go! Keep the disc parallel to the ground to help minimize mess.

  •    Disposal
    • Once you've removed FLEX disc, turn the disc upside down to empty the fluid into the toilet, place the empty disc in a wrapper and dispose in the trash.

FLEX with Heavy Flows

FLEX for Active People

Questions & Answers
1. How much can FLEX Disc hold?

FLEX Disc can hold three super tampons worth of period blood + discharge. Unlike a tampon however, FLEX Disc collects, rather than absorbs, menstrual fluid and is safe to wear for up to 12 hours.

2. Does FLEX Disc work with a heavy flow?

Yes! The majority of FLEX Disc users have heavy flows - including those with endometriosis and PCOS.

FLEX Disc can hold up to 3 super tampons(!) worth of menstrual fluid + discharge. Another major benefit of using FLEX Disc on a heavy flow day is that you can utilize our hands-free emptying trick for a worry-free period for up to 12 hours!

3. Does removing FLEX Disc get messy?

The short answer is that yes, it can get a little messy though most customers find that it's not nearly as messy as they expected. It also gets easier the more you do it.

Many users like to establish a routine with their FLEX Disc usage. Most users will plan their wear around their schedule so they can insert + remove the disc in the comfort of their own home until they get the hang of it. New users will also opt to remove FLEX Disc in the shower.

4. Can I use FLEX Disc with an IUD?

Yes, FLEX is safe to use with an IUD. However, if you have an IUD, you should be informed about your particular IUDs benefits and risks.

5. Is this a menstrual cup?

We love this question! FLEX Disc is not a menstrual cup, it's a menstrual disc and they are very different products.

A menstrual disc is a round, flexible ring with a catch that collects - rather than absorbs - menstrual fluid and other matter discharged from the uterus during your period.

FLEX Disc is also disposable which means you simply throw it away after using. Menstrual cups, on the other hand, must be emptied and rinsed because they are reusable and typically have to be boiled every month to disinfect.

The other big difference is that a menstrual cup sits in the vaginal canal, while FLEX Disc sits at the base of the cervix in the widest part of the vagina called the fornix. This is why you can have sex with FLEX Disc but not a menstrual cup.

Try FLEX with some liners at first.

Sometimes you just feel better with a little backup. FLEX plus liners would be a great combination for you while you transition to FLEX to help guard against leaks until you get the hang of positioning FLEX.
