Menstrual Discs: Complete Guide + How to Use

If you've been in the menstrual product conversation for a while, you've heard about tampons, pads, cups and period underwear. But there's a fifth category quietly winning over converts — menstrual discs. They're different enough from cups that they deserve their own guide, and for many people they turn out to be the option they wish they'd tried years ago.

This guide covers what a menstrual disc is, how it differs from a cup, how to insert and remove one, safety considerations, and how to decide between reusable and disposable versions. Brand-neutral — categories only.

This is educational, not medical advice. If you have questions about a specific health condition, please see a clinician.

What is a menstrual disc?

A menstrual disc is a shallow, flexible disc — usually medical-grade silicone in reusable versions — that you insert into the vagina to collect menstrual fluid. It looks like a soft, thin rimmed bowl. Reusable discs typically last 5–10 years with proper care. Disposable versions are made of thinner materials designed for single use.

Discs have been around for a couple of decades but only recently entered mainstream awareness. The reusable silicone versions in particular have driven the growth, largely because they offer the same "collect not absorb" benefits as cups but with a fundamentally different fit.

How it works — position matters

The single most important thing to understand about discs is where they sit — and why that changes everything.

A menstrual cup sits in the vaginal canal, held in place by a suction seal against the vaginal walls. It's below the cervix.

A menstrual disc sits higher up, in a space called the vaginal fornix — the area around and behind the cervix. It's tucked back and up, with the front rim resting behind the pubic bone. It's not held by suction; it's held by the shape of your anatomy.

That single positional difference explains almost every feature of a disc:

• Most people can't feel it at all, because it's not in the canal
• Penetrative sex is possible with it in — the vaginal canal is unobstructed
• People with a high cervix, who struggle with cups, often find discs fit better
• Some discs allow "auto-dumping" — sitting on the toilet and pushing lightly to release fluid without removing
• No suction means slightly different removal technique

Menstrual disc vs cup — the honest comparison

Neither is universally better — they're different tools. Some people love their cup and don't need anything else. Others try both and prefer the disc. Some own one of each for different situations.

How to insert a menstrual disc

Insertion has a technique to it. Here's the standard approach:

1. Wash your hands with soap and water.
2. Find a comfortable position — sitting on the toilet, one leg raised, or squatting all work.
3. Pinch the disc in half between your thumb and forefinger. Some people use a "taco fold" (pinching the sides together lengthwise).
4. Insert horizontally. Push the disc into the vagina, angling it back and down toward your tailbone — not up. This is the opposite direction from what feels intuitive at first.
5. Push it all the way back until you feel it slide past your cervix.
6. Tuck the front rim up behind your pubic bone with your finger. This is the step that locks it in place.
7. Check. Once positioned correctly, you shouldn't feel it. If you can feel the front rim poking, tuck it further behind the pubic bone.

It takes practice. Most people take 2–3 cycles to feel confident. Don't be discouraged by early leaks or awkward attempts — this is universal.

How to remove it (without mess)

Removal is where discs have the steepest learning curve. Here's the technique:

1. Sit on the toilet. First-time removal is much less nerve-wracking here.
2. Hook a clean finger under the front rim — the one you tucked behind your pubic bone.
3. Pull down and out slowly and steadily. Try to keep the disc horizontal so fluid stays inside.
4. Empty into the toilet or a sink.
5. Rinse with clean water and reinsert (reusable) or dispose (disposable).

Some spillage on removal is normal at first. Doing it over the toilet (not the shower floor) makes any spills a non-event.

Auto-dumping (with some discs): When your disc is in and full, you can sit on the toilet, bear down gently as if going to the bathroom, and the disc will tilt slightly to release its contents into the toilet — without removing the disc itself. It resettles into position when you relax. Not all discs work this way, and it takes practice to do without shifting the disc completely, but many users find it a game-changer.

Period sex with a disc

This is one of the main reasons discs have gained popularity. Because the disc sits above the vaginal canal, penetrative sex is possible and mess-free with most discs in place. Your partner won't feel it, and you shouldn't either.

Important caveats:

• Discs are not contraception. Use appropriate birth control separately.
• Discs do not protect against STIs.
• Sex may occasionally shift the disc — check position after.
• Not every disc is designed for this use — check the manufacturer's guidance.

Reusable vs disposable

Reusable menstrual discs (typically medical-grade silicone) last 5–10 years, cost $30–50 upfront, and generate no waste after purchase. They require rinsing between uses and sterilizing between cycles (boiling in water for 5–10 minutes).

Disposable menstrual discs are thinner and made for single use. They're useful for travel, first tries, or people who don't want to deal with cleaning. They cost more per use over time and generate waste.

Many people start with a disposable to try the format, then switch to reusable once they're comfortable. Others prefer disposables long-term for convenience.

Who a disc suits best

Discs tend to suit:

• People with a high cervix who find cups get lost
• People who want the option of period sex
• People with a heavy flow who want maximum capacity
• People with an IUD (discuss with clinician — some evidence suggests reduced expulsion risk vs cups due to no suction, though guidance varies)
• People with a sensitive bladder, since discs don't press on the urethra the way cups sometimes do
• People who found cups uncomfortable but still want a reusable internal option

Discs may be less suitable if you have very short fingers relative to a high cervix (removal requires reaching to hook the rim), certain pelvic floor conditions, or if you struggled with cups specifically because of insertion (removal is harder with a disc).

If a cup didn't work for you but you liked the idea of a reusable internal product, a disc is worth trying before giving up on the whole category.

Safety considerations

General safety points for menstrual discs:

• Don't exceed the manufacturer's maximum wear time (typically 12 hours)
• Wash hands before insertion and removal
• Sterilize reusable discs between cycles
• Never share a disc
• Very rarely, TSS has been associated with menstrual products — if you develop sudden high fever, rash, vomiting or dizziness, remove and seek urgent medical care
• If you have an IUD, discuss disc use with your clinician
• Stop use if you experience pain, unusual discharge, or difficulty removing

Frequently asked questions

What is a menstrual disc?

A menstrual disc is a shallow, flexible disc worn inside the vagina to collect menstrual fluid. Unlike a cup, which sits in the vaginal canal held by suction, a disc sits higher up in the vaginal fornix — tucked behind the pubic bone. This position means most people can't feel it, and mess-free period sex is possible while it's in place.

What's the difference between a menstrual disc and a menstrual cup?

Both collect menstrual fluid, but they sit differently. A cup sits in the vaginal canal held by suction and comes in silicone. A disc sits higher, in the vaginal fornix, held by the pubic bone and doesn't rely on suction. Discs typically hold slightly more fluid, allow period sex, and can be easier for people with a high cervix. Cups are typically reusable for years; discs come in both reusable and disposable versions.

How do you insert a menstrual disc?

Wash your hands, then pinch the disc between your fingers to fold it in half (some people use a taco fold). Insert it horizontally into the vagina and push it back and down along the vaginal wall, aiming toward your tailbone. Tuck the front rim up behind the pubic bone. When positioned correctly, you shouldn't feel it. It takes a few tries to get comfortable with — that's normal.

Can you have sex with a menstrual disc in?

Yes — one of the main appeals of a disc is that it enables mess-free period sex. Because the disc sits above the vaginal canal in the vaginal fornix, penetration doesn't disturb it. Discs are not a form of contraception and do not protect against STIs — use appropriate contraception separately.

How long can you wear a menstrual disc?

Most menstrual discs can be worn for up to 12 hours before emptying, similar to menstrual cups. On heavier days you may need to empty every 4–8 hours. Always follow the specific manufacturer's guidance. Wearing longer than recommended raises the risk of leaks and, very rarely, TSS.
