Can You Use a Menstrual Cup with an IUD? A Gynecologist's Guide

If you have an intrauterine device (IUD) and are considering switching to a menstrual cup, you're not alone. This is one of the most common questions we hear from women who want to make the transition to reusable period care. The short answer is yes, you can use a menstrual cup with an IUD — but there are important precautions to keep in mind.

Let's break down everything you need to know, with expert insight from our OB-GYN team.

Understanding How an IUD Works

An IUD is a small, T-shaped device inserted into the uterus to prevent pregnancy. There are two types:

Both types have thin strings that hang down through the cervix into the upper vaginal canal. These strings allow your healthcare provider to check that the IUD is in place and to eventually remove it.

• Hormonal IUDs (such as Mirena, Kyleena, or Liletta) release progestin to thin the uterine lining and thicken cervical mucus
• Copper IUDs (such as Paragard) use copper to create an environment that is inhospitable to sperm

The Main Concern: IUD Strings and Suction

The primary worry about using a menstrual cup with an IUD is the suction effect. When you remove a menstrual cup, breaking the seal creates suction that could theoretically pull on the IUD strings.

The evidence here is genuinely mixed, and it is worth being straight about that. A 2012 study published in Contraception found no significant difference in IUD expulsion rates between menstrual cup users and women using pads or tampons. However, a later systematic review of menstrual cup safety (Lancet Public Health, 2019)30111-2/fulltext) collected several case reports of IUD expulsion in cup users and concluded that a possible association cannot be ruled out, while the overall quality of evidence remains low. In practice this means: cups and IUDs are widely used together, the absolute risk appears small, but no cup — including ours — can claim to protect your IUD.

The key is proper removal technique — which we'll cover below.

Tips for Safely Using a Menstrual Cup with an IUD

1. Wait After IUD Insertion

After getting an IUD placed, wait at least one full menstrual cycle (or as your doctor advises) before using a menstrual cup. This gives the IUD time to settle into its proper position and reduces the risk of displacement.

2. Learn Where Your Strings Are

Before using your cup, familiarize yourself with where your IUD strings sit. Your healthcare provider may trim the strings short, but they can vary in length. Knowing their position helps you avoid accidentally pulling them when removing your cup.

3. Always Break the Seal First

This is the most important step. Never pull your menstrual cup out by the stem without first breaking the suction seal. To break the seal:

The Leia Cup has air holes near the rim that help release suction more gradually, which many users find makes removal easier. This is a comfort feature, not a proven safeguard for an IUD.

• Pinch the base of the cup firmly
• Gently press one side inward to release the vacuum
• Only then begin to ease the cup out

4. Don't Position the Cup Too High

A menstrual cup should sit in the lower part of the vaginal canal, below the cervix — not up against it. If your cup sits too high, it could come into contact with IUD strings. The Leia Cup's anatomically contoured shape naturally positions itself in the optimal location, away from the cervix.

5. Check Your Strings Regularly

After each period, take a moment to check that your IUD strings are still in place. If you notice they feel longer, shorter, or you can't find them at all, contact your healthcare provider. These changes could indicate the IUD has shifted.

Which Menstrual Cup Is Best for IUD Users?

Not all menstrual cups are created equal when it comes to IUD compatibility. Here's what to look for:

The Leia Cup was designed with these principles in mind: a reinforced rim for reliable sealing, a softer body that reduces the force needed to release the seal, and a short contoured shape intended to sit below the cervix. To be clear about what this does and does not mean — these are design choices, not proven clinical outcomes. We have no study showing that Leia reduces IUD displacement, and we do not claim it does. Whichever cup you use, breaking the seal properly before removal is what matters most, and your own clinician's advice comes first.

• Softer silicone — generates less suction force, which is more comfortable to release (no cup has been shown in clinical studies to lower IUD expulsion risk)
• Proper air holes — help release the vacuum seal gradually during removal
• Anatomical shape — sits lower in the vaginal canal, away from the cervix and IUD strings
• Not too long — shorter cups are less likely to interfere with IUD positioning

When to See Your Doctor

Contact your healthcare provider if you experience any of the following while using a menstrual cup with an IUD:

• You can feel the hard plastic of the IUD at the opening of your cervix
• Your IUD strings seem significantly longer or shorter than usual
• You cannot find your IUD strings at all
• You experience unusual cramping, pain, or heavy bleeding
• You suspect the IUD may have shifted or been partially expelled

Frequently Asked Questions

Can a menstrual cup pull out an IUD?

While theoretically possible if the cup is removed incorrectly (without breaking the seal), the risk is very low with proper technique. Always pinch the base to release suction before removal.

Should I use a smaller menstrual cup with an IUD?

Not necessarily. The right cup size depends on your anatomy, flow, and cervix height — not your IUD. However, choosing a cup with softer silicone and good air holes is advisable. Our size guide can help you find the perfect fit.

Can I use a menstrual disc instead?

Menstrual discs sit higher in the vaginal canal, closer to the cervix, which may increase the risk of contact with IUD strings. A menstrual cup that sits lower, like Leia, may be a safer choice for IUD users.

How soon after IUD insertion can I use a cup?

Most healthcare providers recommend waiting at least one menstrual cycle. Some suggest waiting two to three cycles. Always follow your doctor's specific advice.
