I have been using flex since 2019 and I don't know how I ever lived before. I originally got it since I was on my period during my honeymoon and wanted to have some mess-free period sex, and it definitely did the trick! Since then I've been using them every month; they are easy to insert (after a little of practice) and there is no leaking: I can wear thongs and don't need any sort of liner. I no longer have any cramping! It's so wonderful I have to literally set a timer on my phone to change them out because I forget. Being a nurse and working 12-16 hours, these are a must-have.
I also love the subscription plan; I was pregnant and it was great to pause my subscription or modify it at anytime.
This has changed my life! Everyone needs this!
