HOW IT WORKS

A helpful guide to Flex Disc insertion, wear & removal.

PINCH

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

INSERT

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

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.

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.

    Truly AMAZING

    Never have I thought I would review a period product, but this one is worth the review! I am truly so impressed by the Flex Disc.

    First of all, so comfortable ~ you really cannot notice it is there at all. I was intimidated by the disc at first but the tutorial video via QR code on the box was helpful & reassuring. First day of my period I tried it and went to the gym after ~ no leaks at all, which was stunning as someone with a heavier flow!

    Second & pairing with comfortability is also security. I felt secure using this product and reassurance against fear of TSS (especially with previous use of tampons). The flex disc is a real game changer in that regard.

    I really can speak so highly of this product ~ it takes a moment of learning for use, but really is so easy, so comfortable, and so secure. Thank you tons to all the thoughtful minds who made this! You really changed my periods for the better in so many ways!

    SAVED MY LIFE FROM THE ENDOMETRIOSIS SUPER HEAVEY FLOW

    I have used tampons plus backup pads for most of my life due to my super heavy flow and horrible debilitating periods plus endometriosis. When I first discovered Flex discs I was skeptical that it would be any better than what I was used to. I WAS WRONG! These things are a game changer: I can swim, I can work long shifts, I can do whatever I want while wearing one and the only thing that happens when my flow is at its heaviest is a bit of auto-dumping when I go to the bathroom. If the disc becomes too full, the seal is broken by the force of the pelvic muscles during urination. However, when that happens all I have to do is (with clean hands) push it back into place. They have given me back my freedom. Also, I have never given birth (as is recommended before you use certain kinds or sizes menstrual cups) and these are very easy for me to insert.

    Unfortunately, using flex discs did not lessen the severity of my cramps, but that was not the reason I switched to them and I wasn’t too disappointed because I know my cramps and period pain are extremely severe. So that wasn't a dealbreaker.

    A word of advise: if you have to poop, wash your hands before going to the toilet and remove the disc FIRST, empty your bowels, wash your hands again THOROUGHLY, and then insert a new disc. In my personal experience, it’s very difficult to insert the disc when you are about to poop because there’s less space in the vagina when the rectum is full.

    The only people I wouldn’t recommend these…

    10/10 love

    I got the disposable ones because I wasn’t sure about a reuseable flex disc and these are great, weird to insert at first but once you get used to it it’s a life changer. My cramps have been nonexistent and my periods are actually shorter! It’s great to not have a tampon string or have to worry about smell. I will say if you don’t change after 12 hours or if you have very heavy flow there is a risk of leakage but it depends on each person, I only had leaks the first period I tried this

    Absolute Game Changer

    I first tried them 2023. I used Cups before but wanted to try Discs for the longest. I hate Tampons and Pads. Flex was a Game Changer for me. Currently we are in Germany and I even have them shipped here since they are not available on Base or in any local Drugstore. So worth it. My Period was usually super heavy and long. Now since using the Discs and Period Panties my Flow isn’t as heavy and long anymore. It took some Practice to get them sit comfortably but once you figure it out it’s smooth sailing.
