Birth control is an important concern for all who are in the reproductive phase of their life. People want options that are safe, readily available and convenient. An IUD (Intrauterine Device) is a popular option and IUD users often want the option to combine it with a practical menstrual cup.
But can a menstrual cup and an IUD be used together?
Yes. You can use a menstrual cup and IUD together. Just follow our simple tips below to make sure that both your menstrual cup and IUD work well together.
What is an IUD?
IUDs, also known as coils, are small, t-shaped devices inserted into the uterus to prevent pregnancy. Lasting for years— between five and ten -they mean you can have sex without condoms or other contraception. Just make are sure that both you and your partner don’t have any STIs as IUDs don’t protect you against sexually transmitted infections.
Your family doctor, gynaecologist or reproductive health care professional will be able to advise you on which one will work best for your body and your needs. It may be an IUD which releases hormones or one without. Tell your health care professional that you are using or thinking of using a Ruby Cup and ask them to trim the strings a little. Ask them when you can start using the menstrual cup after your IUD has been inserted as each person is different.
After inserting the IUD you will be called back for a 6-week check-up. If you forgot to mention that you wanted to use a Ruby Cup when you had it inserted, now is a good time to ask if you can start using a menstrual cup. You will also be asked to check that you can feel the strings regularly to make sure that it hasn’t moved. You can do this just before inserting your menstrual cup.
Can a menstrual cup dislodge an IUD?

You can ask the strings to be trimmed when it is first inserted.
Can the suction of your menstrual cup interfere with your IUD?
