you got this

Insert - Wash your hands and the FLEX Cup for 20 seconds. Press the sides of the cup together and then fold it in half again forming a tight ‘U’ shape. OR place a finger on the top rim of the cup and press it down into the center making the top smaller for insertion. Get in a comfortable position, relax your vaginal muscles, insert the FLEX Cup into your vagina, sliding it up and back toward your tailbone (not straight up).
Wear it for up to 12 hours.
Remove - Simply pull the ReleaseRing™ to break the seal and remove. The ReleaseRing™ pulls the top of the cup in to break the seal and help prevent spillage during removal. Before using or reusing, remove the ReleaseRing™ and thoroughly wash the cup for 20 seconds with warm water.

Wonderful cup for first time users

So I have been looking into cups for years now. There are so many different kinds out there and honestly it's kind of intimidating when you don't really know what to look for. So after years of wondering around the internet and seeing the flex come up a few times I decided to look into. I personally came on the page to check out the flex disc because I liked the idea of still getting my period but not actually having it interfering with my daily life. I also have an IUD that I didn't want to risk pulling out. So after talking with my OBGYN and getting the ok from her I decided to continue my journey. When I looked at the flex cup I couldn't decide between the slim fit or the the larger one.. once looking into a little more and with some.help from the website I went with the slim fit. There is like hardly any difference between the two but if you have a really really heavy flow you may need that itty bitty more space. It took a week to get to me and came like a day or two before my monthly friend came. I boiled it and and popped it in like the installation video suggested. For my first month not gonna lie I checked every time I went to the bathroom because that's what I was use to.. never once did I leak or have an accidental spill. I'm not on my second month of use and I completely forget it's even in. The last two periods are the most comfortable periods I have ever had. This thing last the whole 12 hours never spilling over or leaking, I'm not uncomfortable doing anything I…

Very useful and easy

I have used menstrual cups now for the past 3 Yeats I'd say and by far this one has been the best. I was concerned about the pull tap, I thought I would be able to feel it but it's not the case. It's also easier to remove and stays in place for 12 hours. I have 2 daughters and the slim for me worked great but I also only menstruate for 3 days (TMI). I definitely recommend!

Don’t Wait...Do It Now!!!!

I really wish they had invented this a long time ago. I finally discovered the flex cup at age 51 and will never look back. I gave away all of my feminine hygiene products because I don’t want to use anything else. The learning curve was interesting but now it’s like second nature. I LOVE LOVE LOVE my Flex cup!!!

Amazing!

I had always wanted to try a menstrual cup but thought it looked tricky to use. how wrong i was! Once I got the hang of it-which took me a day, i had no trouble inserting and removing it! I can leave it for 12 hours without emptying it (and even then, it's not nearly even full!) I cant feel it and almost forget it's in. I am now trying to convert other friends and families. So glad to no longer have to purchase pads and tampons!

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.
