“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.”

is easy to use

Pinch.

FLEX may look big but it’s actually smaller than a tampon when you insert it. Start by washing your hands and pinching it in half.

Insert.

Use your index finger to guide the front edge, tucking it up behind your pubic bone. You shouldn’t be able to feel it at all if it’s in the right place.

Wear it for 12 hours.

Swim, workout, have sex, go to the bathroom, sleep, all without having to worry about leaks or changes.

Remove.

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

Dispose.

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

Life saving!

I was hesitant to try this product due to a previous bad experience with the nuvaring birthcontrol, however I am completely blown away at how phenominal this product is. Watch all the videos and read the tips for insertion and removal to ease any nerves. I was successful on my first try, and completely forget that I'm menstruating while using this product. I personally get tons of pain and cramping while using tampons that would put me in the fetal position for hours, with this I have no pain or cramping which is a life saver for me.

Love the disc!!

I absolutely love the Flex disc!! I got it in right on the first try without any leaks! I also have the Flex cup and I like it but the disc is much easier to put in and seems like less hassle. No more tampons or pads for me!! I will definitely tell every woman I know about the Flex disc!

Day 3 of Period: Game Changer

I’m currently on day 3 of my period and this has been an absolute game changer. If you’ve never used a cup-like product before, the mess is a little daunting at first but you only have to deal with it once every twelve hours. (Definitely take their advice about removal in the shower for the first few tries!) Menstrual cups have never worked for me because of their shape/size and this has worked perfectly literally every time I’ve used it. I haven’t had any leaks yet!

Love!!

This is my first cycle using them and WOW. It was a little intimidation at first but after 2 days or so, I got the hang of it and it was second nature. Super comfortable. Also, the period sex claim is legit. Which is my fav part about it ;)

Comfortable, effective, and it's true you can have period sex!

I switched from tampons to flex discs probably 6 months ago give or take. I don't even know if I can call it comfortable because I cannot feel it AT ALL ( to the point that my first period trying them I freaked out when I had realized I completelyforgot it was in). I have a pretty heavy flow and I have had no issues with the 12 hour wear. I usually ensure it's popped in place anytime I use the restroom, for the most part it stays where it's meant to while using the restroom. I have also tested the period sex claim, neither my partner or I felt it at all and there was no leakage. I still cannot wrap my head around the semantics for period sex, but hey it all worked out! It is a little messy removal wise but not enough to deter me. I am extremely happy I made the switch. I am no longer constantly worrying about leaks or changing tampons or what the chemicals are doing to my body. If you're on the fence about trying it, just do it! Yes, the cost is a little bit higher than tampons but a box of disc's honestly lasts longer since there is more time between when it has to be changed out, better "absorbancy" and so on and so forth. 100000% recommend.

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.
