Here is one users experience of using the menstrual cup.
Benefits of Using the Cup
There are so many benefits to switching to a cup. I have my reasons, in order of importance.
Comfort- When I wear a cup I cannot tell it is there. There are no strings, no weird cramps, and no pads that can be very uncomfortable. I have forgotten I was on my period several times. Some women report fewer menstrual cramps and a lighter or more regular flow after using the cup for a while. Unlike tampons and pads, cups do not pull any moisture away with them and only hold your flow.
Less changing- I used to change tampons at least 4-6 times a day. They just weren’t comfortable to wear any longer than that no matter how heavy my period. I can go all day without changing my cup and usually change first thing in the morning and then before bed. You could go an entire day of work or school without having to rummage for a tampon at the bottom of your purse in the public restroom.
Less waste- Since switching I have not purchased or wasted any more plastic packaged tampons. No more applicators, packaging, or actual feminine products being tossed or flushed.
No more chemicals- Feminine hygiene products are exposing you to more than just cotton.
Stop the midnight Target run and save money- I haven’t had an “oh shit” moment when starting my period since using a cup because my cup is always right where I left it. Running out of tampons and making my husband run to the store late at night is no longer an event we face. If I only had one cup it would have paid for itself twice over since starting to use it. Maybe even more. You’ll need to replace your cup every few years but that is nothing like buying a box or more of disposable products each month.
