When menstruation becomes a regular part of your life, it's easy to forget the significance of it. After all, getting a period every month means your body is prepared to give life to another human being. That's a pretty big deal, right?

But when you're actually on your period, that detail understandably gets lost amidst the mood swings, the cramps, and the occasional worry that your tampon string might be poking out of your bathing suit at the beach.

Luckily, Kourtney Kardashian is here to put that whole tampon-string struggle into perspective. (Related: Do You Really Need to Buy Organic Tampons?)

ICYDK, Menstrual Hygiene Day happened earlier this week, and Kardashian commemorated the occasion with an Instagram post and an article on her new lifestyle site, Poosh. (Related: The Weirdest Products On Kourtney Kardashian's New Site Poosh)

The IG post shows Kardashian and Shepherd hanging out at the beach in their bikinis. In the caption, Kardashian admits that Shepherd voiced a possible concern about the photo: "'Is my tampon string showing?' @steph_shep whispered to me."

As relatable as it is to worry about a visible tampon string, Kardashian took this opportunity to talk about why it's actually pretty silly to feel self-conscious about these things. "The source of life shouldn't be embarrassing or hard to talk about," she wrote. "Mothers, teach your sons too."

Kardashian then encouraged her followers to head over to Poosh to read Shepherd's article about menstruation and learn more about period hygiene.

Shepherd's column sheds important light on the lack of menstrual hygiene resources in certain parts of the world (particularly in Sub-Saharan Africa) and how that affects young women.

"Many girls stop going [to school] entirely once they start their period," Shepherd wrote. But with menstrual hygiene interventions in place, girls can "overcome obstacles to their health, freedom, and opportunities such as gender-based violence, school dropout, and child marriage," she explained. "Not only does this benefit girls individually, it also benefits the countries in which they live."

An example of a menstrual hygiene intervention? A pair of underwear—yes, really. Girls in developing countries like Uganda not only lack access to menstrual hygiene products, they also have trouble finding clean underwear to hold said menstrual products in place.

Enter: Khana, a nonprofit that aims to "ensure every girl has the panties she needs to manage menstruation and stay in school—starting with Uganda," explained Shepherd, who sits on the organization's board of directors. Khana uses funds from donations and online sales to give girls the underwear they need, and the clothing is actually manufactured in Uganda to create jobs and boost the economy. "Exceptional quality for you, equal opportunity for her. That's the possibility of just one pair," Shepherd wrote.

Kudos to Kardashian and Shepherd for using their platforms to support women around the world, and for reminding people everywhere that conversations about menstruation, both big and small, are too important to feel embarrassed about.
