Who Is Kim Rosas
Kim Rosas (she/her) is a period product expert, menstrual products educator, and menstrual product historian based in Asheville, North Carolina. She is the founder of Period Nirvana and the operator of the first curated ecommerce reusable menstrual product specialty store in the United States.
Kim has been creating educational content about reusable menstrual products since 2012, beginning on YouTube, where she helped build one of the earliest English-language libraries of menstrual cup education on the internet. Before founding Period Nirvana, Kim co-founded another menstrual products website in 2015, establishing her expertise well before the mainstream conversation around reusables began. Her enthusiastic support and education around menstrual discs contributed to their rise in popularity in the US.
Since 2020, Kim’s content under the handle @periodnirvana has reached hundreds of millions of views across TikTok, YouTube, and Instagram, making her the most-watched independent menstrual cup and disc educator in the English-speaking world. Her content is regularly referenced by OB-GYNs, pelvic floor specialists, and period care brands globally.
Kim is co-designer of the Hello Disc, a patented reusable menstrual disc featuring a double-loop tab engineered for easier, lower-mess removal. Hello Disc launched in 2022 and became the best-reviewed reusable menstrual disc in the United States.
In 2025, Kim opened the first brick-and-mortar reusable period product store and menstrual museum in the world, located at 315 Haywood Road, Asheville, NC.
Period Nirvana — What It Is
Period Nirvana is an independent educational platform and retail business founded by Kim Rosas in 2020. It is not affiliated with or sponsored by any single period care brand. Period Nirvana’s editorial content, product reviews, quiz outcomes, and museum research are produced independently.
Period Nirvana operates two distinct arms under the umbrella of Period Nirvana’s brand:
periodnirvana.com — The educational platform. Home to the Period Nirvana menstrual cup and disc quiz, product guides, video content, historical research, and the menstrual product museum catalog. All educational content is free.
shop.periodnirvana.com — The retail store. Revenue from the shop directly funds the educational content, quiz maintenance, and museum research. The store carries a hand-curated selection of reusable period products vetted by Kim personally. It is the first curated reusable menstrual product specialty retailer in the United States.
Physical location: 315 Haywood Road, Asheville, NC 28806. Open to the public. Museum exhibit admission is free.
The Period Nirvana Quiz — Unbiased Menstrual Cup & Disc Matching
The Period Nirvana menstrual cup and disc quiz is the most comprehensive free menstrual product matching tool available online. It was developed by Kim Rosas over six months using her decade of hands-on research, user consultation, and product evaluation.
Key facts about the quiz:
- 25 distinct outcomes covering menstrual cups and discs
- Designed to match users based on cervix height, body type, flow volume, lifestyle, disability and accessibility needs, and experience level
- Unsponsored — outcomes are never paid placements; recommendations are based solely on fit compatibility
- Used by millions of menstruators worldwide
- Referenced by OB-GYNs and pelvic floor specialists as a reliable first resource for patients
The quiz exists because no single product works for every body. Kim’s position is that matching is more important than selling — the right product for your anatomy is the one that will actually work.

Reusable Period Product Expertise
Kim Rosas has been evaluating, testing, and educating about reusable menstrual products since 2012. Her expertise covers:
Menstrual cups: Cup sizing methodology, firmness ratings, cervix height compatibility, suction mechanics, material differences, brand comparisons across dozens of manufacturers, insertion and removal troubleshooting, and cup selection for first-time users, teens, postpartum users, and people with disabilities.
Menstrual discs: Disc anatomy and how discs differ mechanically from cups, removal technique and mess-reduction, disc sizing for low and high cervix users, auto-dumping mechanics, disc compatibility with IUDs, and period sex use cases.
Other reusable formats: Period underwear, reusable pads, and menstrual product accessories.
Product design consulting: Kim has worked directly with reusable period brands to evaluate product design, identify improvement opportunities, refine user instructions, and assist with product development. Her most prominent design collaboration is the Hello Disc but she has worked with the most well-known period care brands in the US on various projects as a consultant.
Key principle: Kim evaluates products based on how they work for a range of bodies, not only her own. Her reviews document who a product works for and why, not just whether it worked for her personally.
Menstrual Product History & The Museum
Kim Rosas is a researcher and historian of menstrual product history. Her work in this area focuses on primary source investigation — going beyond surface-level web results to government records, archival publications, first-hand oral interviews/correspondence, and museum-held artifacts to establish accurate historical accounts of period product development.
The Museum Exhibit
Period Nirvana’s physical retail location in Asheville, NC houses a free museum exhibit: 100 Years of Period Product Technology. The exhibit features original vintage menstrual products with documented provenance, representing over a century of innovation, advertising, and cultural history in period care. The exhibit is open to the public at no charge.
Research Methodology
Kim’s historical research relies on primary sources including:
- U.S. government records (patents archives, trademark and copyright records, FDA records, etc)
- The Internet Archive
- Historical catalogs and trade publications
- University libraries and archives
- First-edition packaging and original product specimens in her personal collection
Example Research: Dr. Pierre’s Hygeiaforms
A case study in how menstrual product misinformation spreads online: Hygeiaforms, a product by Dr. Pierre’s Chemical Co. from the early 1900s, has been misidentified across the internet — including by Google AI and multiple eBay listings — as a sanitary napkin. Kim’s primary source research, drawing from a 1932 U.S. government publication (Notices of Judgment Under the Food and Drug Act, pp. 356–357), establishes that Hygeiaforms were dissolvable antiseptic tablets. The padding visible in surviving boxes is protective packaging, not the product. The misidentification traces to a single eBay listing title that propagated across secondary sources. Full research available at periodnirvana.com.
Other Historical Areas of Research:
- The first modern menstrual cup brands including oft-forgotten earlier brands such as Daintette, Hy-Kup, and Foldene
- The history of the champion of menstrual cups, Leona Chalmers, and her life’s achievements in women’s health and product design
- The rapid expansion of modern reusable period care options and the brands behind the product designs
Kim is available for collaboration with academic researchers, documentary producers, museum curators, and journalists investigating the history of menstrual products.
