Menstrual Cups and IUDs—Can You Use Them Together?

Menstrual cups have become a game-changer for many women looking for a comfortable, eco-friendly, and cost-effective period solution. At the same time, intrauterine devices (IUDs) are one of the most reliable forms of birth control. But can these two coexist?

The short answer? Yes, you can use a menstrual cup with an IUD—but with a few precautions.

Let’s break down everything you need to know to use your cup and IUD safely without worrying about dislodging your birth control.

How an IUD and a Menstrual Cup Work Together

First, a quick refresher:

• An IUD is a small, T-shaped device inserted into the uterus by a healthcare professional. It has thin strings that hang down through the cervix into the vagina.
• A menstrual cup is a flexible, reusable cup that sits in the vaginal canal to collect period blood.

Since both are inside the vaginal area, it’s important to use the cup correctly to avoid any interference with your IUD.

How to Safely Use a Menstrual Cup with an IUD

1. Wait After Your IUD Insertion

If you just got your IUD, give your body time to adjust before using a menstrual cup. Doctors often recommend waiting at least 6 weeks before inserting anything into the vagina—including cups, tampons, or sex toys.

2. Know Your IUD Strings

Your IUD has small strings that hang down into the vaginal canal. These strings allow your doctor to check placement and remove the IUD when needed.

Before using a menstrual cup:

• Ask your doctor to trim the strings shorter if they feel long.
• Learn how to check your IUD strings so you can tell if your IUD has shifted.

3. Insert Your Menstrual Cup Correctly

Proper insertion ensures your cup and IUD can peacefully coexist. Here’s how:

• Angle the cup downward toward your tailbone instead of straight up.
• Make sure the cup is sitting low in the vaginal canal, not too high near the cervix.
• Check for a good seal by running a finger around the base of the cup.

4. Break the Seal Before Removing the Cup

This is the most important step. Never yank your menstrual cup out without breaking the suction first- IUD or not!

To remove it safely:

• Pinch the base of the cup to release the suction.
• Rock it gently side to side as you pull it out.
• Avoid pulling on your IUD strings accidentally.

Improper removal is one of the biggest risks of IUD displacement, so always be gentle and take your time.

5. Check Your IUD Placement Regularly

Every month, after your period, do a quick IUD string check:

• Wash your hands and insert a clean finger into your vagina.
• Feel for the thin, firm strings near the cervix.
• If the strings feel shorter, longer, or missing, your IUD might have moved.

If anything feels off, schedule a visit with your doctor.

Will a Menstrual Cup Dislodge My IUD?

While rare, IUDs can get displaced. However, studies show that the risk of IUD expulsion is not significantly higher for menstrual cup users compared to non-users.

The key to preventing this is:

• Breaking the suction before removal.
• Making sure your cup sits low in the vagina.
• Checking your strings regularly.

Who Should Avoid Using a Menstrual Cup with an IUD?

You may want to skip the menstrual cup if:

• Your doctor advises against it due to medical reasons.
• You have a history of IUD expulsion.
• You’re unable to check your IUD strings or feel uncomfortable doing so.

In these cases, you might consider other period products like organic pads or period underwear.

Final Thoughts

Yes, you can safely use a menstrual cup with an IUD—as long as you take a few simple precautions. Always break the suction before removal, check your IUD placement regularly, and consult your doctor if you notice any changes.

With the right technique, you can enjoy the benefits of both a menstrual cup and an IUD without worry!
