Can I use a menstrual cup with an IUD?

As long as you’re careful to avoid accidentally suctioning or pulling your IUD strings when you remove your menstrual cup, it’s fine to use a cup and an IUD together. Research has found that the use of tampons or menstrual cups does not increase the risk of an IUD coming out early. The packaging information for IUDs can be inconsistent, but you can use whatever your usual menstrual product is and not increase your risk of your IUD coming out.
