1. One menstrual cup will last you forever.

(According to Diva Cup's website, you replace annually. Many other eco sites claim that with proper care, one cup could last 10 years.)

2. Save money.

Even buying one cup a year will cost you much less than a box of pads or tampons each month.

3. Visit the pharmacy less.

Even if you replace your cup annually, that's 11 times fewer a years than if you used disposable products.

4. Get an extra five hours between changes.

Tampons offer just eight hours before TSS becomes a possibilty. With menstrual cups, you can go up to 12 hours between emptyings.

5. Hold more liquid.

A normal tampon holds between six and nine grams of liquid. Menstrual cups hold almost five times that amount, capable up to one ounce (about 28 grams). That makes life a lot more easy for ladies with a heavier flow.

6. Dodge chemicals going *up there*.

Cups don't contain latex, BPA, dye or other creepy additives. Not to mention, almost all tampons contain bleached rayon - a material that creates the possibly carcinogenic byproduct dioxin. Plus, that is BLEACH you're shoving up there. Menstrual pads arnt any less innocent, only slightly less invasive.

7. Suffer less leaks.

With proper insertion, your menstrual cup should form a suction. Meaning. All liquid should pool directly into it without a hitch. When a tampon shifts or becomes saturated, that's when leaks can happen.

8. Decrease your chance of TSS.

Toxic Shock Syndrome is a bacteria-spurred illness that can kill you. If your tampon has even a slightly higher absorbency than your actual flow, you risk shredding. Tiny bits of cotton can cause small cuts in your vaginal walls - a perfect breeding ground for the bacteria causing TSS.

9. Don't dry out.

Cotton in tampons can strip your vagina walls of naturally occurring lining, making your lady bits more susceptible to disease.

10. ...no, really.

Tampons absorb extra juices tiny ducts in your vagina walls released when you're sexually aroused. So when you remove it before Bonesville, it could make for a rougher trip. In addition, some brands like the Softcup claim that you can wear it during intercourse mess-free!!!

11. Ward off rashes.

Yep, adults can actually contract diaper rash. Pads can create chafing in the absolute last place you'd want it.

12. Lighten yor purse.

No more self-combusting tampons or runaway pads to tote around or accidently fall out with your wallet. You have the cup, that's all you need.

13. Juggle less.

Cups can handle any stage of your period - unlike tampons, with you should be careful to match an absorbency to your specific flow that day.

14. Sleep better.

Even if you're having a *super* night, the cup holds more liquid so you won't have to fumble in the dark to change your pad or tampon.

15. Rock on after childbirth.

Most cups come in two sizes - one before childbirth and one after. The one after is slightly larger and accommodates your body's changes.

16. Go untethered.

Tampon strings have the pesky, gross habit of getting soaked in pee or worse - popping out to make an appearance at the pool or beach... or bathtub.

17. Get to know your body.

Since the cup clears up all mystery about your exact flow volume, you should have the chance to learn about your unique cycle. It's your body, after all, shouldn't you know these things?

18. They arn't that scarey.

Cups are just as comfortable as tampons, once you get the hang of them. (Remember middle school? See. Tampax weren't always your BFF.)

You can maintain cups in a public restroom, but you probably won't have to because you can keep it in for so long. Just wash your hands and wet a paper towel to bring into the stall with you. Then you can safely empty your cup into the toliet, wipe it out with the towel and pop it back in for another dozen hours.

Does the idea of collecting your flow in a cup gross you out? Then likely collecting it in a cotton vagina plug or slab of adult diaper does, too. In that case, good luck.
