Do Menstrual Discs Leak When You Sit? | How Menstrual Discs Work
If you’re new to menstrual discs or considering switching from pads or tampons, you may wonder: Do menstrual discs leak when I sit? And how exactly do these flexible little discs work?
Here’s everything you need to know about how menstrual discs function—and whether they’ll stay leak-proof when you move, sit, or sleep.
🩸 What Is a Menstrual Disc?
A menstrual disc is a reusable or disposable internal menstrual product made from medical-grade silicone or polymer. Unlike tampons and menstrual cups, which sit in the vaginal canal, discs sit at the vaginal fornix, the widest part near the cervix.
Think of it like a shallow bowl that collects blood instead of absorbing it. Many users choose discs for their:
-
High capacity (up to 70 mL)
-
Longer wear time (up to 12 hours)
-
Mess-free intimacy
-
Reduced risk of leaks
✅ How Does a Menstrual Disc Work?
A menstrual disc works by being inserted horizontally into the vagina and tucked behind the pubic bone. This creates a secure seal that holds the disc in place, even during movement.
Insertion Steps:
-
Wash your hands.
-
Pinch the disc to make it narrow.
-
Slide it into the vagina at a horizontal angle.
-
Tuck the front rim securely behind the pubic bone.
The disc then collects menstrual fluid in its basin, which you remove, empty, rinse, and reinsert every 8–12 hours.
💺 Do Menstrual Discs Leak When You Sit?
The short answer: They shouldn’t—if inserted correctly.
When properly tucked, the disc forms a seal at the top of the vaginal canal, and sitting or standing shouldn't cause leaks. However, leaks can occur for a few reasons:
🔹 Common Causes of Leaks When Sitting:
-
Incorrect placement – If the disc isn't fully behind the pubic bone, it may slide or tip.
-
Overfilled disc – Sitting adds pressure to the pelvic floor. If the disc is full, it might auto-dump a bit.
-
Size mismatch – Some bodies may need a disc with a wider or narrower rim to fit comfortably.
-
Sudden movements – Deep squats or coughing can sometimes unseat a poorly placed disc.
🛠️ How to Fix It:
-
Always check the placement: you shouldn’t feel the disc at all.
-
Empty the disc before it’s full.
-
Choose the right disc size for your anatomy (some offer S and L).
-
Practice a few insertions—just like tampons, it takes a little time to get right.
😴 What About Sleeping or Exercising?
Menstrual discs are great for overnight protection and active days. When placed correctly, the disc stays in place during:
-
Sleeping on your side or back
-
Jogging, yoga, dancing
-
Intimacy (many users say it’s mess-free!)
👩⚕️ Do Gynecologists Recommend Menstrual Discs?
Yes! Many OB-GYNs recommend menstrual discs for their long wear time, lower odor, and reduced waste compared to pads or tampons. They’re especially helpful for people with heavy flow who want fewer bathroom trips.
