Best Thing Ever

After more than a decade of no periods due to an IUD, I had it removed and restarted. I discovered that my former go-to, tampons, were very uncomfortable, and I could not get a cup in comfortably. I decided to take a chance on these, and actually looked forward to my period. It was amazing. Though I did have a day or so of a tricky removal, ultimately it was like not having a period at all. I was so comfortable, not a single leak, and I couldn't even feel it. I highly recommend, and I rarely feel strongly enough about anything to recommend. It is awkward, especially if you're on the heavy side, like me, but it was the best. I am going to try re-usable discs, but will definitely get these again, if necessary! I'm talking them up to my 12 year old too, as she hates tampons.

Flex Runs the World

You guys. Stop what you’re doing and buy these!! I suffer from endometriosis including heavy periods (think adult diapers to bed), migraines, severe cramps, etc. Flex are life changing. I just empty it once or twice a day, it’s easy to insert, it doesn’t smell, it’s disposable, they ship automatically... I mean, I recently went off birth control and was almost in tears dreading my period but these have made them bearable. Thank you thank you thank you. Never going back.

Ahhhhmazing

This is honestly a game changer! I had tried a cup and could never get it to work for me. First time and I loved it, it has never leaked and truly works the full 12 hours! I don't think I will ever go back to pads and I will never go back to tampons!!!

Game Changer!!!

Ok not gonna lie, I initially bought them so I could have sex during my period, but I was so impressed with them that I wear them all the time! You genuinely can’t feel them, tampons you can still kinda feel. My cramps were not as bad. Please try them!! You won’t regret it!

Period game changer

I started using Flex Discs in December and I can officially say I’ll never go back to using tampons EVER! The first couple of times I used a disc I was terrified and I wasn’t exactly comfortable. I definitely had a little bit of anxiety with the removal a couple of times too. Here’s a few tips and reasons I love the discs..

*I usually have light periods with 1-2 heavier days and I still only need to change them out every 12 hours and the disc is so darn comfortable that you don’t even know its in.

*I remove the disc in the shower to not worry about spillage and put the new one in with ease

*I can wear white, a bikini, swim and have sex and never worry about any leakage

*NO period pain anymore...seriously, periods don’t have to be painful

*Travel with no worries of finding a bathroom every few hours to change a tampon....nope not anymore!

Thanks Flex ladies! You’ve changed the period game and I appreciate you so much!

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.
