“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.
“Flex was basically life changing because I didn’t have to worry about changing it.”
Lauren
“I found this to be 10x more comfortable than a cup while I was lifting.”
Meg Squats
“Flex was great because it slides in and out and there’s none of that horrible cotton pull.”

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.
