Trois femmes qui rient en culottes menstruelles


You’ve got questions. We’ve got answers. Lots of ’em.


Each pair Mme L'Ovary daytime undies includes 3 removable pads, so you can stay dry in the same pair all day long.

You can change your pads as the day progresses and according to your flow.

In other words, just one pair of Mme L'Ovary's daytime undies is equivalent to 3 pairs from another brand.

Mme L'Ovary's products are practical, economic, and, well, awesome!

In the product descriptions of every item we stock, you can find a size guide that shows the measurements associated with each size.

Strong odours are produced when blood comes into contact with synthetic materials like plastic.

The reaction between our blood and the chemical components in sanitary pads or tampons is what's responsible for those strong smells you sometimes notice.

It's super important not to associate your menstrual blood with smelly and embarrassing waste!

When blood comes into contact with natural fibres like cotton, the smell is way softer and more neutral.

What are we trying to say? It's simple. You've got nothing to worry about if you're wearing a pair of Mme L’Ovary panties.

You betcha! Mme L'Ovary is every menstrual cup's best friend, an ideal COMPLEMENT or even an outright replacement! With our undies, you can choose when you want to let your blood flow out naturally – no need for a foreign object to collect it inside you. Go that route, and not only will you likely feel pretty liberated, you’ll also get fewer menstrual cramps. And even if you do wear your cup throughout the day, it’s always nice to get a break at night. According to Health Canada and several gynecologists, you shouldn’t leave a menstrual cup inside your vagina for more than 4 to 6 hours. Something to think about! For more information on why you might want to choose menstrual panties over menstrual cups, Check this out!

Mme L'Ovary's undies can be used in cases of mild incontinence, meaning you don't have to worry about those itsy-bitsy oopsies! But we don't recommend them for severe incontinence.

Yep! We design our undies for all types of flows.

The only thing is that people who have heavy flows will change their removable pads more often than people with moderate or light flows.

We also offer MAXI pads to anyone looking to boost their protection during heavier flow days. Our products can be easily tailored to fit your needs!

Everyone uses them differently based on their flow, lifestyle, and sense of comfort.

Yep! Depending on your flow.

During those early days after you give birth, your flow can be pretty heavy. When that happens, you've got two options:

- our daytime period panties with a MAXI pad

- or our nighttime panties, which offer more protection in the front and back.

After a few days, your flow should ease off.

Once that happens, you can switch to our daytime panties, which come with three removable pads (each with absorption equivalent to a regular pad). You'll be able to change pads according to your flow and sense of comfort!

After the sun goes down, our nighttime period panties offer protection that can go hours without being changed. (absorption equivalent to a MAXI pad)

If you've had a caesarean section: Thanks to a lot of great feedback from our community, we can now suggest which styles you should use if you've had a C-section.

The Highty and  The Highty Nighty have higher waistbands than some of our other styles, so they won't irritate your scar.

The Lacy  also has a higher and softer waistband, so they're cozy around your hips.

Menstrual panties make a smooth and simple transition into the life of a young teenager.

Wash and care

You clean them just like normal undies, except you take 1 extra step: rinse them in cold water.

It's as simple as that!

See the maintenance guide for more details.

Yep, that's always preferable because we handle them a lot when we make them and put them in our classy little carrying bags.

Yep! Discoloration of both your pad and panties is normal. Nothing to stress about!

It's caused by acid from your mucus membranes and menstrual blood. And guess what? Acidic vaginal secretions are a sign of good health!

You can consult your doctor or gynecologist to get more information or to have your vaginal pH tested.

No, at Mme L'Ovary, we're proud to offer menstrual underwear certified without PFAS by the external labratory QUIMA.

PFAS, also known as "forever chemicals," are synthetic chemical compounds that can have harmful effects on human health and the environment.

We're aware that many period underwear brands on the market use PFAS, and we're firmly committed to providing a safer and healthier alternative.

We believe that all menstruating people deserve access to menstrual products that honour their bodies, without compromise ♡

* Certified in april 2023 - Test : US States Requirement, Per-and Polyfluoroalkyl Substances (PFAS) Content (Total Fluorine Method).

Nope. We made the choice not to use chemical processes that treat fabrics with metal nanoparticles.

Unlike other menstrual underwear brands, we prefer to avoid these procedures because studies have yet that prove that there's no risk to consumer health.

They have the same lifespan as your "normal" panties, but the difference is that you'll wear them once a month (or maybe twice if you wear them twice in the same week).

If you take good care of them, they should last for many years!

We offer removable pads made of 100% organic cotton, they are not dyed and are made especially for people who can't tolerate any dye.

We pay close attention to the fabrics we use for fabrication.

A pair 100% organic undies would have cost more, and our goal is to make our products accessible to as many people as possible.

That's why Mme L'Ovary's products aren't currently made of organic cotton, but we're open to going that route in the future!

Our undies are 94% cotton and 6% lycra.

For people who are very sensitive and have problems with irritation related to dyes in underwear, we offer our 100% organic cotton removable pads, which are made without dye.

Mme L'Ovary is a Quebec-based initiative with a commitment to be ECO-RESPONSIBLE and ETHICAL.

We design everything in Quebec, and then we go to the city of Medellin in Colombia (nicknamed the "Undies Capital" because of its many expert seamstresses!) for manufacturing, which we personally manage and supervise ourselves, in a workshop that meets ethical, social, and environmental standards. In addition, the fabrics we use are made in right there in Colombia.

Every one of Mme L'Ovary's removable pads fits into our daytime undies and absorbs as much as regular protection. Worn alone, the undies can absorb as much as a panty liner, and that gives you a whole extra layer of protection.

Each pair of Mme L'Ovary nighttime undies is equivalent to an overnight maxi pad and reaches higher both up front and behind, so you're sure to feel dry when you wake up. 

We've used different types of fabrics in a specific order and design to ensure maximum absorption.

Among other things, our undies are made of cotton, fleece, PUL(a material also used in cloth diapers), and absorbent fabrics.

DAY: Our daytime undies have built-in protection equivalent to a panty liner. But here's the thing: the pouch inside lets you insert removable pads to bulk up your level of protection. You can change sanitary pads as needed throughout the day.

NIGHTTIME: Our nighttime styles can be worn on their own, just the way we made 'em, because their absorbent fabrics are sewn directly inside. The absorption surface is larger and protects you both behind and in front. Whether you sleep on your back or your stomach – you can even sleep on your head! – it absorbs the equivalent of a nighttime maxi pad.
