is a menstrual disc like a diaphragm?

While a menstrual disc and a diaphragm are both inserted into the vaginal canal, they serve completely different purposes. A menstrual disc, such as the my mimi disc, is designed to collect menstrual blood and can be worn for up to 12 hours, including during penetrative sex. A diaphragm, on the other hand, is a contraceptive device that must be used with spermicide and removed before intercourse. Although both are reusable, their usage, materials, and functions are fundamentally different.

Let’s take a closer look at the differences between a menstrual disc and a contraceptive diaphragm.

menstrual disc vs. diaphragm

Feature	Menstrual Disc	Diaphragm
Primary function	Collects menstrual fluid during your period	Prevents pregnancy by blocking sperm from reaching the cervix
Placement	Sits in the vaginal fornix, just below the cervix	Fits over the cervix, positioned high in the vaginal canal
Material	Medical-grade silicone or thermoplastic elastomer (TPE)	Typically made from silicone or latex
Insertion method	Folded into a taco shape and inserted to expand in place	Inserted using fingers with spermicide applied, must fully cover cervix
Duration of wear	Can be worn for up to 12 hours	Typically used for 6 to 8 hours
Sexual activity	Yes, suitable for mess-free period sex (my mimi is designed for this)	No, it should be removed before sex
Reusable	Yes – rinse, wash, and reuse each cycle	Yes – must be cleaned and stored between uses
Effectiveness	Excellent for leak-proof menstrual protection	Effective contraception when used correctly with spermicide
Comfort level	Soft and flexible – designed for all-day wear	May require custom fitting and proper placement

do diaphragms and menstrual discs look the same?

At a glance, they might appear similar due to their round, flexible design, but their construction is distinct. A diaphragm is shaped like a shallow dome with a firm rim, while a menstrual disc is more flattened and wide with a softer rim to sit snugly at the base of the cervix. These subtle design differences reflect their unique functions – contraception versus period care.

can a menstrual disc be used for birth control?

No, menstrual discs like my mimi are not contraceptive devices. They are designed to collect period blood, not to block sperm. While they sit in a similar anatomical position as diaphragms, they should never be relied upon to prevent pregnancy. Always use approved contraceptive methods for birth control.

is it safe to use a menstrual disc if i have an iud?

Yes, most people can use a menstrual disc safely with an IUD. In fact, my mimi is specifically designed to be IUD-friendly. Since discs rest below the cervix and don’t rely on suction (unlike menstrual cups), they are less likely to interfere with your IUD strings or placement. Always consult your healthcare provider if you have concerns.

benefits of switching to a menstrual disc

Longer wear time – up to 12 hours without changing
Reusable and eco-conscious – great for the planet
Can be worn during sex – mess-free intimacy
Suitable for heavy flows – holds more than a tampon
IUD-safe design for peace of mind

conclusion: understanding the difference

Although a menstrual disc and a diaphragm share a similar shape and position in the body, their purposes could not be more different. If you’re looking for a reusable, eco-friendly way to manage your period with maximum comfort and flexibility, a menstrual disc like my mimi may be your perfect fit. Just remember – it’s not birth control. Always use the appropriate method for your reproductive needs.
