Considering the switch from tampons? Period innovation is here to give you freedom.

Flex Disc sits somewhere different

Flex menstrual disc insertion diagram

Unlike other period products that sit in the vaginal canal, Flex Disc sits in the vaginal fornix. Plus, Flex Disc collects fluid rather than absorbing it like a tampon.

“Flex was designed to solve many of the problems caused by traditional menstrual products. It doesn't change the vaginal flora reducing the risk of infections and has not been linked to toxic shock syndrome."


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



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.

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



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.



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.



Pour the liquid into the toilet, and wrap the disc in toilet paper (or a Flex Eco Disposal Pouch) before tossing it in the trash.

    To scared to even try this product. Just feels very intimidating!

    I have been using these for a few years now. I was usually fine with just a regular tampon and pads, until I hit Perimenopause. Then they got so heavy that I became anemic. Iron supplements helped, but I really still don’t knowhow I would be able to hold employment at this stage without this disc. I mean, it self-empties when you pee! That is the most convenient thing ever on a work break. (I do still wear a pad just in case.)

    Never thought at 48 yrs of age I'd find Life Changing Period Protections

    I switched to the Flex discs single use first and yes the first time there's a learning curve but I then ordered the cup and then they reusable disc and I can't imagine dealing with tampons anymore. I also don't get yeast infections like I use to. I just ordered the bamboo pads. I wish Flex was around 20 years ago. Our daughters all use the Flex products now too! Life changing for so many reasons!

    These have changed my life. I felt like I had tried everything, including a cup and I was seriously contemplating sleeping in adult diapers because I was so uncomfortable sleeping during my period and then my sister told me about these. My first couple days I have to wear a panty liner with them (which is fine) but then the rest of my period I completely forget about it. I could never go back to tampons or pads.
