Is It Safe to Use a Menstrual Cup with an IUD?

When birth control emerged in the 1960s, it revolutionized reproductive health, and intrauterine devices (IUDs) brought added convenience by eliminating the need to remember daily pills. Today, as menstrual cups and discs gain traction, questions arise about their compatibility with IUDs.

Research indicates a potential increased risk of IUD expulsion when using menstrual cups or discs. A 2020 study showed that 14% of menstrual cup users experienced IUD expulsion within a year, compared to 5% of non-users. By the two-year mark, expulsion rates rose to 23% for cup users versus 6.5% for non-users. Most expulsions occurred during cup removal due to suction or accidental pulling on the IUD strings. While no specific studies focus on menstrual discs, their rim-based design might reduce suction-related risks.
To minimize expulsion risks, consult your doctor about trimming IUD strings flush to the cervix and carefully breaking the cup's seal during removal. Regularly check your IUD strings after menstruation for changes in length or position.
Reusable menstrual discs may offer a safer alternative as they don't rely on suction and allow for penetrative sex without mess. However, further research is needed to confirm their safety with IUDs. If you’re not certain inserted period products are right for you, leakproof period panties offer a reliable and safe alternative that will save money, and are better for your body and the planet. Always discuss options with your healthcare provider to make informed choices for your body.
