Discs And Tampons Comparative 1 Disc = 3 super tampons

FLEX sits above the vaginal canal where it can move with your body and can’t be felt at all. Sleep through the night, swim or enjoy mess-free period sex. Ready to challenge your period as well?

Watch our how-to video here
  1. Insert - Wash your hands, pinch the disc in half and insert it into the vaginal canal by pushing the edge that goes in first down toward the floor. Tuck the rim above your pubic bone.
  2. Wear it for up to 12 hours.
  3. Remove - With clean hands, slide your finger up under the front edge of FLEX Disc and pull straight down, keeping it parallel to the floor.
  4. Dispose- Turn disc upside down to empty in toilet. Place the empty disc in a wrapper and dispose of in the trash.

Are you afraid to try it? We totally get it, trying something new can be challenging but once you nailed it, your period will never be the same. The disc can’t be felt at all once in place. If you need help, our team of amazing FLEXperts are here for you at hello@flexfits.com

Never in my life have I loved being on my period until I found the flex desk! I have really long, heavy periods that end up having a lot of large blood clots. I always bleed through my tampon and typically end up changing it every hour. I have to buy ugly plain “granny panties” to wear during my periods because I always end up bleeding through. I’ve ruined clothing, bedsheets, get embarrassed about smell, and am consistently in and out of the bathroom to the point that it affects my life on the daily when I am on my period because of how much I have to change my tampon. There’s been times that I’ve had to put down a panty liner, use a tampon, and even fold pieces of toilet paper because of how heavy my periods get. I even avoided going to the gym because I was terrified that I would bleed through while I was working out. I decided to get flex when I saw it at Walgreens. I also bought tampons just in case. Let me tell you that I was skeptical at first! There were a lot of claims in the commercials, on the packaging, and videos I have watched, honestly I didn’t think that it would work at all. I thought I was gonna have the same problems that I always have had. I thought to myself “ no way 12 disk we’re going to last through my whole period!” That night I got home I open the box before I went to bed and I struggled to get it in. 😅 I watched a few instructional videos a few times and finally I got it…. and I actually learned a lot about my anatomy when using this product, I…

Very honest review

I have been intimidated by any period product other than tampons. But I was sick of buying them, tired of the cramps, and felt awful about the waste. These flex discs are an absolute game changer. I tried the disposable ones first because they’re thinner; and it gave me an idea of how the reusable one would work/feel. I felt NOTHING. No leaks, very easy to insert and remove. Not as messy as I thought it would be, and these discs have been through the ringer with me. I experienced a really heavy flow with blood clots and it held up with no spillage and cramps felt like nothing. It’s so refreshing to go to sleep with it in and not worry about bulky pads or TSS. I have it a whirl with sex and I freaked out at first because since it’s against the cervix, it got pushed back. Once my muscles relaxed after the deed has been done, it settled back into place. Not a speck of blood on either of us. I’ve been recommending this to anyone that will listen. Game changer

Game Changer!

***Absolute beginner review***I had read a little about menstrual discs and cups but never tried either. I had grown tired of tampons and they were starting to become uncomfortable. I purchased the disc yesterday, tried it after watching the tutorial videos and got it in perfect position on the first try! I will say I'm very comfortable with my anatomy and getting blood on my hands doesn't bother me, these things probably helped me with proper placement. I couldn't believe it was working but it was and I felt nothing! I kept checking for leakage expecting to find some, but never did. It was amazing! Guess what? I had mess free sex a few hours after putting it in! I'm completely sold on this product and kicking myself for waiting so long to try it.

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.
