8 FAQ about menstrual cups

Menstrual cups are hardly a new idea. In fact, the first menstrual cup was invented in 1937 by a woman named Leona Chalmers. It was met with a lot of resistance and didn’t make as big as an impact as Chalmers had hoped. Over the years, menstrual cups have become more and more popular but, still, people have a lot of questions about this seemingly-odd bell-shaped cup. Understandably! With pads and tampons being the most mainstream types of period care products, it can be hard to find solid information on menstrual cups. Fear not - we are here to answer your bloodiest questions.

1. What are the holes in menstrual cups for?

Those holes at the top of the cup are not there for decoration! They play an important role in making sure that the cup is easy to remove. These holes can get blood caught in them over time, so make sure to clean your cup thoroughly after every cycle.

2. How much blood can a menstrual cup hold?

Lunette menstrual cups come in 2 sizes. Model 1 can hold about .85 fluid ounces of blood and Model 2 can hold up to 1 ounce. This might not seem like much but the average person only releases about 2-3 tablespoons (or 1.5 ounces) of blood during each period.

3. Can you wear a menstrual cup longer than you can wear a tampon?

Oh yeah you can! Tampons shouldn’t be left in for more than 4 to 8 hours, depending on your flow because they absorb (and dry!) and can cause micro wounds. Menstrual cups are good to go for up to 12 hours. That’s right - you can stop worrying about whether you have enough tampons to last through the day. But, if you have a heavy period, you might want to empty it more often to prevent leakage.

4. Can you get Toxic Shock Syndrome from a menstrual cup?

Great question! It’s possible but highly unlikely. There are very few cases of TSS relating to menstrual cup use that have been reported. At least of one of the cases was due to very prolonged use. Neither of the cases were related to Lunette Menstrual Cups.

5. You aren’t supposed to use a tampon on light flow days but can you use a menstrual cup?

The reason you shouldn’t use a tampon on light flow days or spotting days is because your vagina is much drier during this time. Since tampons are absorbent, this could dry you out even more and increase your risk of Toxic Shock Syndrome. Menstrual cups are non-absorbent (they collect the blood, instead of soaking it up) so you can use it whenever you’d like.

6. How long should a menstrual cup last?

Menstrual cups can last for several years. We recommend replacing your period cup every 1-2 years. You should replace yours if it has any tears, holes, or just isn’t in good condition anymore. 

7. Can I do inverted yoga poses with a menstrual cup in?

There has been a lot of debate over whether you can do yoga while on your period and even more questions about whether doing upside down poses will cause your blood to leak all over you. Thanks to the suction of the menstrual cup, this isn’t something you should worry about. Staying upside down for a long time might weaken the seal but if you’re just going through asanas in a class, rest easy.

8. If I’m allergic to latex, can I still use a menstrual cup?

You sure can if the cup is made of silicone! Lunette menstrual cups are made of medical grade silicone, so you can bleed without worrying about a latex allergy.

Menstrual cups are the period care of the future. The more you know about how they work, the easier it will be to rock your cup all period long. Check out all our menstrual cup options at Lunette.

    Hi tillie!

    Even if you haven’t used your cup in a year or so, you can still start using it again now :) Just make sure that your cup is in good condition, so that it does not have scratches, cracks or any signs of deterioration and you are good to go. If your cup does not seem to be completely intact and in good condition, please replace it!

    Hi Asli,
    thank you for your message. A menstrual cup won’t loosen or widen the vagina. When you have the cup in your vagina, your vaginal and pelvic floor muscles keep it in. So you actually kinda work out when you wear the cup.
    Best regards, Team Lunette

    I love using Lunette but have a concern. Somehow it feels like it might cause my vagina to expand and lose tightness over time. Is it something I should worry about?
