Key Takeaways:

• Cups sit lower in the vaginal canal and stay put with a suction seal, while discs sit higher in the vaginal fornix and tuck behind the pubic bone without relying on suction to seal.
• Discs hold more and can be worn during sex, while cups tend to feel more familiar to tampon users and are easier for beginners.
• The best pick depends on your flow, your anatomy, whether you have an IUD, and what your day actually looks like.

If you're considering reusable period care products, the cup-versus-disc question comes up fast. Both options collect your flow instead of absorbing it, both are reusable, and both can be a real lifestyle upgrade. At Cora, we make both because there's no single right answer, just the right fit for you.

The core difference comes down to placement. A menstrual cup sits in the vaginal canal and uses a gentle suction seal to stay put, roughly where a tampon goes. A menstrual disc sits higher, behind the cervix and pubic bone, and does not use suction to seal. That one difference shapes nearly everything else.

The Easy-Does-It Cup and cups like it have been the reusable go-to for years. Menstrual cups can be great because they offer:

• Familiar placement if you've used tampons
• Reliable seal that holds up through activity
• Long-term usage, as they last for years with proper care
• Multiple sizes for different bodies

That said, the suction takes practice to break on removal, and a cup's suction also may, in very rare cases, dislodge an IUD. Menstrual cups also need to come out before penetrative sex, and a weaker pelvic floor can affect the seal.

The Perfect Fit Disc sits differently, which gives it a different set of perks:

• Discs hold the most of any period product, great for heavy days
• Can be worn during penetrative sex
• Does not use suction to seal
• Comfortable for people with a low cervix or a weaker pelvic floor
• One size, so there’s no guesswork involved in matching a size to your body

Menstrual discs can have a steeper learning curve for insertion and removal, and they can also be a little messier coming out.

Match your period product to your real life:

• New to internal products? A cup's tampon-like placement is the gentler intro.
• Heavy flow? A disc's higher capacity means fewer changes.
• Want period sex? A disc is the one that stays in.
• Low cervix or weaker pelvic floor? A disc often sits more comfortably.

Plenty of people keep both on hand and switch depending on the day. There's no wrong choice — just pick what feels best for your body.

If either is placed correctly, you shouldn't feel it. Feeling it usually means it needs a small adjustment.

Discs generally have the highest capacity, which is why they're popular for heavy flow and long days.

Yes, both can typically be worn up to 12 hours. Empty sooner on heavy days and never exceed the recommended wear time.
