So happy I stepped out of my comfort zone!
As a black woman in my mid-40s, it’s been interesting trying new methods and using new tools for my feminine health needs… But I am thrilled to say that by stepping out of my comfort zone (in this and other areas) I discovered Flex Period Discs and there’s no way I’m going back! Ha ha.
I am doing my best to share this positive message with my doctor, my family and my friends, because most women from my community have no idea that products like this are out there and available to us.

Better than a cup!
I have been using a menstrual cup for several years now, to save money and be eco friendly. The cup had a learning curve for insertion and removal, and even after years of use, I would still sometimes be spending 10+ minutes in the morning trying to get it to open and suction. I had the opportunity to try a flex disposable disc for the first time and wow! No learning curve for me- went in so easy. Taking it out was no problem either. I wore it on my heaviest day and didn’t have any leaks even after 12ish hours. So satisfied that I preferred a kit the next day! I’m excited to have the option of my old cup and a new reusable flex disc. I work outdoors and sometimes don’t have access to a bathroom for 8+hours, so tampons and pads don’t work well for me. Happy to be done with them for good now.

AMAZING!!!!
I truly cannot feel it at all, it is a little difficult at first to insert it and be sure its behind your pubic bone, but my cramps have been so much better so far! It can be a learning curve but once you get the hang of it, SUPER EASY!!! I do recommend getting a box of gloves just for removal purposes, because it can be messy or i could even recommend removing in the shower as well.

Bye tampons and pads FOREVER
I bought these for a vacation where I was going to have my period. I was so upset but hopeful for these.
I gotta say, I am *never* going back to tampons and pads. It's comfortable, lasts for 12 hours and I had sex with it inside of me - no leakage and my partner had no idea. You honestly cannot feel it inside of at all.

Frequently Asked Questions

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 re-worn. 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.

Have Qs? Feel free to reach out to our Flexperts: Call 800-931-0882 or email help@flexfits.com.

How do I insert Flex Disc?

First, wash your hands. 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!

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! Then, tuck the front rim above and behind 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 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! Learn more here.
