My Experience With a Menstrual Cup

There is a product on the market right now that holds twice as much menstrual fluid (blood) than a tampon. That same product has little to no risk of health risks such as toxic shock syndrome. Its true, menstrual cups are slowly gaining traction as a viable alternative to menstruation care. In addition, using tampons and pads each month can be both expensive, wasteful, and in many cases are tested on animals. If youre looking to break out of the usual menstrual routine, there might be a perfect product for youthe menstrual cup.

What is a menstrual cup?


Credit:WikiCommons/Menstrual Cup

Menstrual cups are small devices made from soft medical grade silicone and similar safe materials such as latex. It does exactly what the name says, it is a cup for menstrual blood. The cups come in a large variety of colors, shapes, and sizes.

There are some extremely informative instructional videos I highly suggest watching before making any type of decision about a menstrual cup. Knowing about your body and vagina is the first step when thinking about purchasing a menstrual cup. Is your flow light, medium, heavy, or a combination of all of these? Do you have a long or short vagina? Where does your cervix sit? All of these questions will affect whether or not you want to try a menstrual cup and exactly which cup will be the right fit for your body and your lifestyle.

How does it work?

The soft cup can be folded in a few different ways and is then inserted into the vagina. It should work the same as a tampon and feels just the same. Because the cup collects fluid and doesnt absorb it, it doesnt need to be changed nearly as often. Most cups hold about 1 ounce, but some can hold a little bit more. Just to give you an idea, that is about twice as much as a regular flow tampon.

I have been using a fold in which I push one side of the cup down into itself to create a smaller applicator. This seems to work better for me than the U fold in which the cup is simply folded in half. However, it just takes some practice. I may end up switching folds later on once I have a little more experience.

I personally havent had too much trouble getting the cup inserted. However, I have definitely found that I unknowingly tense my muscles a bit, which can definitely give some resistance. So, just remaining calm and relaxed is definitely the key. Another tip I’ve heard is to find some unscented water-based lubricant to help with insertion. Of course, this is not mandatory, but if you’re having trouble with insertion, this might be a good option for you.

Once the cup has been inserted it will open on its own, but every so often it may need a tiny bit of help. It’s suggested to run your finger along the outside of the cup in order to make sure the seal has formed. Other cups also say rotating the cup one full rotation (360 degrees) after it has been inserted will allow any corners to fully open and create a proper seal. This way the user wont experience any leaks while using the cup.

Menstrual cups can be worn for up to 12 hours straight, but can be removed and inserted as many times as needed. When it’s time to remove the cup, pinch at both sides tightly in order to break the seal inside of the vagina and slowly pull out the cup. The fluid can be dumped right into a toilet and flushed. Then rinse out the inside of the cup thoroughly and it’s ready for another insertion. At the end of every day of use the cup should be washed well with unscented soap and either left to dry or patted dry with a cloth. Most cups come with a small cloth carrying pouch for discreet storage as well.

Are there any health risks?

As with any product that is inserted into the vagina, there are some small risks involved. If the item is not cleaned properly, an infection could develop. So, making sure the hands are clean before touching, inserting or removing the cup is an absolute necessity. The cup should always be cleaned thoroughly at the end of every day of use and be allowed to fully dry.

Studies have shown that using the cup does not increase risks of infections such as yeast infections. Whats more, because the cup does not absorb vaginal fluids or menstruation, it does not disturb the natural pH balance and healthy bacteria that naturally clean the vagina.

The cup can be safely worn for up to 12 hours, which is a huge advantage to tampons or pads. Not only for the sake of having to worry about leaks, but also for the possibility of toxic shock syndrome, which occurs when bacteria (the staphylococcus aureus or streptococcus bacterium) enters the body and produces a deadly toxin. Toxic shock syndrome has been linked to tampon use because of the fact that tampons can harbor bacteria when inserted into the vagina and can become a breeding ground for harmful infections. Toxic shock syndrome is very rare and is usually found in usage of super absorbent tampons, but is still a risk nonetheless.

My conclusions/advice about menstrual cup use.

Pros:

Saves money each month.
Creates no waste. So the cup is better for the environment!
Can be worn for long periods of time (up to 12 hours).
Feels no different than a tampon. I cant feel mine at all.
Lowers risk for bacterial infections.
I have had no leakage issues.

Cons:

There is a small learning curve when initially using a menstrual cup.
It costs more money up front. Mine was about $40, but they range from about $20 and up. In my personal opinion spending a little extra on your cup is worth it. Getting something that is better quality will last much longer.
Can be a bit messy. I have found that it’s no messier than a tampon (I have a pretty heavy flow). However, I have been a little clumsy and have gotten blood on myself once or twice.
It can be tricky to remove. As with the rest of the instructions, there is very detailed information and videos about how to combat this issue. Although understandably, this can cause panic in new users.
Positioning can be important. My body does not seem to like when my diva cup sits too low. It seems to affect my ability to urinate. I can still urinate just fine, but I can feel that there is pressure on my urethra and the urine escapes a little slower. However, when I sit the cup up a little higher into my vagina that problem is gone.

There is not a doubt in my mind about menstrual cups. I will continue to use my cup for as long as I possibly can. I have enjoyed learning more about my body and feel I am now more in control of my body than ever before. I feel that most, if not all, of the negative aspects of the cup can be completely eliminated by proper education. Although, every body is different, everyones feelings are different, and menstrual cups might not be the right thing for every person.

This is what happens when a guy from Malden, Mass., sees a weird-looking fish in Boston Harbor, and decides to record his reaction, bro.

“I don’t know, man. I went nuts. We didn’t know what the hell it was,” Michael Bergin told the Boston Globe. “It was scaring me to death, it was like a dinosaur. It was so … ugly.”

Teddy Roosevelt Was Obsessed With Making the Dollar Look Like the Greek Drachma

Mother Jones

<!DOCTYPE html PUBLIC “-//W3C//DTD HTML 4.0 Transitional//EN” “http://www.w3.org/TR/REC-html40/loose.dtd”>

After Sunday’s decisive vote to reject a financial bailout offer, Greece may now be inching closer to leaving the Eurozone—the collection of 19 countries that maintains the Euro. If it does, it will need a new currency, of course, likely the drachma—the name of Greece’s currency going back to ancient times.

Ancient Greek drachma coins, as it happens, were famous for their artistry, especially the handcrafted, high-relief designs—three-dimensional and elaborate—that rose from the faces of the coins. Many coins from Athens featured an owl, the bird representing the goddess Athena, with her face on the flip-side of the coin (the owl design was replicated for Greece’s modern-day 1 Euro coin). “Ancient Greek coins are undeniably some of the most beautiful coins ever produced in the ancient world,” said Philip Kiernan, a professor of archeology at the University of Buffalo where he studies ancient money, a field known as numismatics. “They’re little miniature works of art.”

The Athenian tetradrachm (worth four drachmas) was probably the most commonly used coin, starting around the 6th century B.C., and lasting until the 2nd century B.C., according to Kiernan. The Romans finally sacked Greece and installed their own currency, but at its peak, “Athens once produced what was essentially the US dollar of the ancient world,” Kiernan said. “They were considered, remarkably, a very stable currency in the ancient world.”

“Would that our coins today were as pretty as that!” he bemoaned when I spoke to him.

In fact, the enduring beauty of the ancient drachma has reached far into the modern world, even captivating, for several intense years, President Theodore Roosevelt.

TR thought the designs of US coins at the time were lifeless and stale, unbecoming of a great nation. “I think our coinage is artistically of atrocious hideousness,” he wrote to the Treasury Secretary in 1904. Roosevelt wanted new designs that harked back to the high-relief Hellenic masterpieces, but also captured the spirit of a nation growing in stature around the world.

At a White House dinner the following year, an obsessed Roosevelt located his kindred spirit: an Irish-born, New York-raised sculptor named Augustus Saint-Gaudens, who had already designed the president’s inaugural medal and shared the president’s love of drachma coins. Roosevelt—so moved to redesign the country’s currency that he feared the treasury secretary thought him “a crack-brained lunatic on the subject”—commissioned the master sculptor to make designs for a new penny, $10, and $20 coin. “This is my pet crime,” said the president, referring to his passion for the subject.

Saint-Gaudens got to work. “You have hit the nail on the head with regard to the coinage,” he wrote to the president. “Of course the great coins (and you might say the only coins) are the Greek ones you speak of…”

What emerged from his arduous commission, which was plagued by political, bureaucratic and technological problems, was the famous 1907 $20 gold coin, a.k.a the double eagle, widely regarded as an artistic triumph.

Saint-Gaudens’ Lady Liberty powers towards the viewer of the coin, carrying an olive branch and a torch, with dawn light splintering behind her. The US Capitol building can be seen in the bottom left-hand corner. Law required the artist to use an eagle for the design on the flip side of the corn.

But the coin was hard to make: it took nine strikes from a hydraulic press to fashion each one, making mass production impossible. Fewer than 24 were minted, in February and March 1907, according to the Smithsonian.

“The minting process of the day was not conducive to high-relief coins,” says the US Mint. “As a result, despite being considered one of the most beautiful gold pieces ever minted, Saint-Gaudens’ full vision for the production of an ultra high relief coin was never realized.”

Roosevelt was nonetheless deeply impressed by Saint-Gauden’s work. Writing about the sculptor’s prototypes for a new $10 coin, Roosevelt wrote ecstatically: “Those models are simply immense—if such a slang way of talking is permissible in reference to giving a modern nation one coinage at least which shall be as good as that of the ancient Greeks… it is simply splendid. I suppose I shall be impeached for it in Congress; but I shall regard that as a very cheap payment!”

The sculptor died of cancer in August 1907, amid mounting problems with manufacturing the new coins. His design, though, lasted in some form until 1933—though fundamentally altered from his dramatic, high-relief original.

The fascinating, and quite personal, correspondence between Roosevelt and the sculptor was published in April, 1920, in The Century, which editorialized enthusiastically about the project:

The Century’s article on Roosevelt’s coin obsession, in 1920.

“The President’s share in the new issue of coins, the thought, the patience, the unflagging enthusiasm, and the insistence that he brought to bear is a vivid example of his high regard for the need of artistic development in our national life.”

In 2002, one of the only 1933 “double eagles” known to have survived sold for more than $7 million at auction.

Kevin Vickers, Canada’s Badass National Hero, Is a Portrait of Humility

Mother Jones

<!DOCTYPE html PUBLIC “-//W3C//DTD HTML 4.0 Transitional//EN” “http://www.w3.org/TR/REC-html40/loose.dtd”>

Kevin Vickers, Canada’s sergeant at arms since 2006, is being heralded worldwide as a national hero after he reportedly shot and killed an armed assailant in the nation’s Parliament building Wednesday morning. It was a highly emotional moment when Vickers returned to Parliament today—watch the video above—and was greeted with an extended standing ovation. Witnesses are convinced that Vickers, 58, prevented a large-scale massacre in Ottawa. And though he has not yet spoken publicly about his actions (he’s notoriously modest), his record of public service is proof enough of his exceptional character.

Eight years ago, Vickers celebrated his election as the House of Commons’ top cop by traveling in style from Ottawa to New Brunswick on a brand new Harley. “As a gift, his two daughters bought him a vanity licence plate with the letters SGTATRMS,” wrote Bea Vongdouangchanh of The Hill Times. But his career began nearly three decades earlier as a member of the Royal Canadian Mounted Police (the “Mounties”), who are responsible for policing provincial and criminal cases while monitoring Canadian internal security.

The Mounties were convened in 1873, in part to monitor and deal with Americans who were trading with Native Americans in Canada—cheap whiskey for buffalo hides. Today, the force focuses on issues like organized crime and national security, and has jurisdiction in eight provinces, three territories, 184 aboriginal communities, and three international airports. Vickers signed up almost 40 years ago, and spent 29 years on the force—a true-blue local boy from small town Miramichi who moved up in the ranks over time.

In 2000, he was put in charge of the Burnt Church Crisis, a heated battle in which Canadian fishermen destroyed hundreds of indigenous people’s lobster traps. The Native lobstermen retaliated by trashing fish-processing plants. The Mounties were called in to deal with the tense standoff and resolved it peacefully thanks to Vickers’ “thorough assessment” and “measured response,” according to an account from a book on Canadian policing. In an interview with his hometown paper, Vickers credited his experience delivering milk in Burnt Church and Neguac during summer vacations as vital to his understanding the region’s people—which helped him deal with both sides of the crisis respectfully.

Vickers was also involved in several high-profile investigations involving murders, drug crimes, and a tainted Red Cross blood supply. By the end of his term with the Mounties, he held the title of chief superintendent.

In 2005, he joined the House of Commons as director of security operations, and a year later was elected sergeant at arms. From the start, Vickers led the charge on the development of Canada’s “bias-free policing strategy”—now a part of RCMP officer training—by reaching out to the Canadian Muslim community to discuss cultural sensitivity. He served a security guard for the Queen of Canada herself, and was awarded the Queen’s Jubilee Medal to “honor contributions and achievements made by Canadians,” according to an official fact sheet. He also received the Canada 125 Medal and the RCMP Long Service Medal. The United States has offered Vickers a commendation for his “Outstanding Contribution to Drug Enforcement.”

Vickers has remained humble despite his many plaudits—he insists he’s just doing his job. A 2011 feature on Vickers in The Globe and Mail describes how he defended the right of people to wear the kirpan—a ceremonial dagger carried by baptized Sikhs—in the National Assembly. In response, the World Sikh Organization hosted a dinner in his honor. He spoke with The Globe and Mail about why he stood up for the Sikhs:

“As we go forward, we should ask ourselves what Canada should be when it grows up…We have a long way to go before reaching adulthood. The seizure of the kirpans at the Quebec legislature last winter demonstrates the challenges that lay before us as we continue on this journey of sewing together the fabric of our nation with the thread of multiculturalism. Perhaps it would be beneficial for our country, as a nation, to define its core values. What are the core values of Canada, what makes up the soul and heart of our nation?…I told them Canadian officials that if they made me their sergeant-at-arms, there would be no walls built around Canada’s Parliamentary buildings…and the fact that you may wear your kirpans within the House of Commons proves there are no walls around Parliament and I have kept my promise.”

Nine Gifts the NSA Will Hate

Mother Jones

<!DOCTYPE html PUBLIC “-//W3C//DTD HTML 4.0 Transitional//EN” “http://www.w3.org/TR/REC-html40/loose.dtd”>

In the wake of the Edward Snowden-enabled revelations about the reach of the surveillance state, your more privacy-sensitive loved ones may have spent the year discovering TOR, making the jump to mesh networks or encrypted email, or mumbling about converting their nest egg to Bitcoin.

But now that gift-giving season is well upon us, what’s left to get the security-obsessed person who already has it all? Tin foil hats have a timeless appeal, but here’s a short list of slightly more practical devices:

Camera-Detecting Armor

Surveillance Spaulder Demonstration

stml/Vimeo

London artist James Bridle has thought up a wearable device known as a “surveillance spaulder,” which—through infrared detection—would alert the wearer to surveillance cameras by triggering a small muscle reaction. While not “currently a functioning device,” he claims the device is more than possible given the correct components, power supply, and a little bit of tinkering.

Anti-Facial Recognition Hats

The Perfect Anti-Surveillance Hat?

CafePress

Concerned about having your face detected in photos or by security cameras? If Anonymous’ advice of wearing a mask or continuously tilting your head more than 15 degrees seems a little cumbersome, try the hactivists’ suggested DIY project of making an infrared LED-fitted hat to tuck under the Christmas tree.

Camera-Confusing Eyewear

Anti-Facial Recognition Glasses

Isao Echizen/National Institute of Informatics

Not the DIY type? Professor Isao Echizen at Japan’s National Institute of Informatics may have the answer: eyewear that transmits near-infrared rays to render the wearer’s face undetectable to cameras. Not only will this give someone on your list that cool cyberpunk look, but by keeping their image from being captured it will be harder to track their movements.


Face-Disgusing Makeover

CV Dazzle Make-Up

Adam Harvey/ahprojects.com

For the more fashion-conscious, consider a haircut and makeup using style advice derived from WWI and WWII camouflage techniques. The project, created by NY designer Adam Harvey and known as CV Dazzle, uses “cubist-inspired designs” to break up symmetry and tonal contours, creating an “anti-face” technique the designer claims will confuse the detection algorithms of most facial recognition software.

Drone-Proof Clothing

Adam Harvey’s Stealth Wear

Adam Harvey/ahprojects.com

The stylish options don’t stop at simple facial recognition. Harvey’s more recent Stealth Wear project puts together a series of heat-reflecting burqas, scarfs, and hoodies purported to limit potential drone surveillance. Simply put the clothing on, and you’re blacked out to most thermal imaging. According to the website’s rather garbled recounting of Islamic tradition, the clothing reflects “the rationale behind the traditional hijab and burqa,” acting as a veil to separate women from God—only in this case, “replacing God with drone.”

Reflective Drone Survival Guide

Drone Survival Guide

A field guide to various Unmanned Aerial Vehicles and tactics for hiding from drones printed on an aluminum paper reflective enough to “interfere with the drone’s sensors.” While the price is cheap ($15 or €10), the information is also downloadable for free.

M-65 Jackets

Military Camouflage

SPC Gerald James/Wikimedia Commons

Does your giftee need a new coat? Some military-inspired jackets—already made with a camouflage pattern known as Disruptive Pattern Material—also have infrared reflective coatings that make them harder to spot in certain lights.

Bug Detectors and Noise Generators

All-in-One RF Bug Detector

brickhousesecurity.com

For the slightly more gadget-oriented, noise generators, surveillance bug detectors, and virtually invisible bluetooth earpieces could all make great stocking stuffers—especially for those particularly concerned with being followed or having their conversations tracked. The downside? They all come with hefty price tags.

Abandoned Missile Silo

Minuteman III Silo
Department of Defense/Wikimedia Commons

Of course, if all else fails, you could buy a “luxury survival condo” in a converted Atlas missile silo for the strangely reasonable cost of $750,000 to $1.5 million. The company’s press release promises “extended off-grid living” and walls “designed to withstand a nuclear blast.” At this point, going inside a bunker and unplugging might be the only way to completely remove yourself from the NSA’s all-seeing eye.
