What are Menstrual Cups?

Menstrual cups are reusable feminine hygiene devices made of medical-grade silicone, latex, or thermoplastic elastomer (TPE). These cups are designed to be inserted into the vagina to collect menstrual blood, unlike tampons and pads, which absorb it. They come in various shapes and sizes to accommodate different body types and flow levels. The increased popularity of menstrual cups stems from their eco-friendliness, cost-effectiveness (as they can last for several years), and convenience, offering longer wear times compared to traditional options.

Common Menstrual Cup Side Effects

While menstrual cups are generally considered safe, users may experience some side effects, particularly when first starting out. These issues are often easily resolved with some adjustments to technique and cup selection.

Discomfort and Pain

Discomfort is a common complaint among new menstrual cup users. This often stems from improper insertion, muscle tension, or choosing the wrong cup size. If the cup is positioned incorrectly, it can press against the bladder or urethra, causing a feeling of pressure or the urge to urinate frequently. The cup’s rim can also rub against the vaginal walls, leading to irritation.

• Solutions: Experiment with different folding techniques (C-fold, punch-down fold, 7-fold) to find one that works best for you. Using a water-based lubricant on the rim can also ease insertion. Try to relax your pelvic floor muscles during insertion, as tension can make it more difficult and uncomfortable. If discomfort persists, consider trying a smaller or softer cup made from a more flexible material.

Leaking

Leaking can be frustrating, but it’s often a sign that the cup isn’t properly sealed or is overflowing. An improper seal allows menstrual blood to bypass the cup and leak out. Leaking can also occur if the cup is full and hasn’t been emptied in time. Another reason is if the cup is not fully opened inside the vagina to form a proper seal.

• Troubleshooting Tips: Ensure that the cup is fully opened inside the vagina by running a finger around the rim to check for creases or folds. Squeeze the base of the cup and rotate it to create a better seal. Empty the cup more frequently, especially on heavier flow days. Consider using backup protection, like a panty liner, until you’re confident in your cup’s performance. If leaking persists, you may need a larger cup size or a cup with a firmer rim. Consider reading articles from The Period Blog for additional troubleshooting tips.

Difficulty Inserting/Removing

Many first-time users experience anxiety surrounding insertion and removal. This can be due to unfamiliarity with their anatomy, fear of pain, or simply difficulty maneuvering the cup. Insertion can be challenging if you’re not relaxed, and the cup might feel awkward or uncomfortable. Removal can be tricky if you’re unsure of the proper technique or worried about spilling.

• Detailed Instructions:
  • Insertion: Wash your hands thoroughly. Fold the cup using your preferred method (C-fold, punch-down fold, 7-fold). Relax your body and find a comfortable position (squatting, sitting on the toilet, or standing with one leg elevated). Gently insert the folded cup into your vagina, angling it towards your tailbone. Once inside, release the fold and allow the cup to open. Run a finger around the rim to ensure it’s fully open and sealed against the vaginal walls.
  • Removal: Wash your hands thoroughly. Relax your body and find a comfortable position. Reach inside your vagina and locate the base of the cup. Pinch the base of the cup to break the seal. Gently wiggle the cup downwards, avoiding pulling on the stem alone. Once the cup is near the opening, tilt it slightly to avoid spilling the contents. Empty the cup into the toilet, wash it thoroughly, and reinsert.
• Folds:
  • C-fold: Simple and easy to learn, but can be wider for insertion.
  • Punch-down fold: Creates a smaller insertion point, good for those with tighter vaginal openings.
  • 7-fold: Similar to the punch-down, offering a narrow profile for easier insertion.
• Relaxation: Deep breathing exercises and pelvic floor relaxation techniques can make insertion and removal easier and less stressful.

Allergic Reactions/Irritation

Although rare, some individuals may experience allergic reactions or irritation to the materials used in menstrual cups. Most cups are made of medical-grade silicone, which is generally hypoallergenic. However, some people may be sensitive to silicone. Latex cups are available, but they pose a risk for those with latex allergies. TPE cups are another option, but their hypoallergenic properties can vary. Irritation can also occur from improper cleaning or residue left on the cup.

• Recommendations: Choose hypoallergenic options, such as medical-grade silicone or TPE, and carefully read the product label. If you suspect an allergic reaction, discontinue use immediately and consult with a healthcare professional. Always clean and sterilize your cup thoroughly before and after each use to remove any potential irritants.

Infections

One of the main concerns for users of any internal menstrual products is the risk of infections, bacterial vaginosis or yeast infections. However, menstrual cups are not inherently more likely to cause infections than tampons or pads if used correctly. Infections typically arise from poor hygiene practices, such as failing to wash hands before insertion and removal or not cleaning the cup properly.

• Prevention: Always wash your hands thoroughly with soap and water before inserting or removing your menstrual cup. Clean the cup with mild, unscented soap and water after each use. Sterilize the cup between periods by boiling it in water for 5-10 minutes or using a specific menstrual cup cleanser. Store the cup in a clean, breathable container when not in use. Consider reading guidelines from the CDC on hygiene for more information.

Toxic Shock Syndrome (TSS)

Toxic Shock Syndrome (TSS) is a rare but serious bacterial infection associated with tampon use. While the risk of TSS with menstrual cups is considered significantly lower than with tampons, it’s essential to understand the potential risk and take precautions. TSS is caused by toxins produced by Staphylococcus aureus bacteria.

• Minimizing Risk: Although rare, it’s important to empty your cup every 4-8 hours to prevent the buildup of bacteria. Clean and sterilize the cup regularly as recommended. Be aware of the symptoms of TSS, which include sudden high fever, rash, vomiting, diarrhea, dizziness, and muscle aches. If you suspect TSS, remove the cup immediately and seek medical attention. It is also important to see the instructions on Menstrual Cup Side Effects

Impact on IUDs

There is a potential risk of dislodging an IUD (Intrauterine Device) during menstrual cup removal. The suction created by the cup can potentially pull on the IUD strings, leading to dislodgement.

• Recommendations: Consult with your healthcare professional before using a menstrual cup if you have an IUD. They can provide personalized advice based on your individual situation. When removing the cup, be sure to break the seal completely before pulling it down to minimize the risk of dislodging the IUD. Some doctors recommend using a menstrual disc instead of a cup, as it sits higher in the vaginal canal and is less likely to interfere with IUD strings.

Bladder Irritation

A menstrual cup may press against the bladder, leading to irritation or frequent urination. This is most likely to happen with a larger sized cup that is more rigid.

• Recommendations: Try using a smaller, more flexible cup made of silicone so that it provides less pressure against the surrounding tissue.

Vaginal Dryness

Although menstrual cups do not absorb moisture, dryness can still occur in some cases. This is caused by the cup disrupting the natural lubrication of the vagina.

• Recommendations: If this occurs, use a water-based lubricant during insertion to ease the process.

Less Common but More Serious Risks

While most menstrual cup side effects are minor and easily managed, there are some less common but more serious risks to be aware of.

Pelvic Organ Prolapse (POP)

Pelvic Organ Prolapse (POP) is a condition where the pelvic organs (bladder, uterus, rectum) descend from their normal position. Some have suggested that straining during menstrual cup removal might contribute to POP, but strong evidence supporting this direct link is lacking.

• Important Note: The connection between menstrual cup use and POP is largely theoretical. However, to minimize any potential risk, it’s essential to use proper removal techniques and avoid excessive straining. If you have concerns about POP, consult with your healthcare provider.

Vaginal Ulceration/Erosion

Vaginal ulceration or erosion is extremely rare but can occur due to prolonged pressure or ill-fitting cups. This involves the development of sores or lesions on the vaginal walls.

• Prevention: To prevent ulceration or erosion, ensure that the cup fits properly and doesn’t cause excessive pressure or rubbing. If you experience any pain, discomfort, or unusual symptoms, remove the cup immediately and consult with a healthcare professional.

Minimizing Risks and Choosing the Right Cup

Selecting the right menstrual cup and practicing proper hygiene are crucial for minimizing risks and ensuring a comfortable experience. Consider the following factors:

• Size and Shape: Choose the appropriate size and shape based on your age, parity (whether you’ve given birth), and cervical height. A higher cervix may require a longer cup, while a lower cervix may benefit from a shorter cup.
• Material: Medical-grade silicone is the most common and generally hypoallergenic material. TPE is another option, but latex should be avoided by those with latex allergies.
• Cleaning and Sterilization: Clean the cup with mild, unscented soap and water after each use. Sterilize the cup between periods by boiling it in water for 5-10 minutes or using a specific menstrual cup cleanser.
• Insertion and Removal Techniques: Practice proper insertion and removal techniques to avoid discomfort, leaking, and potential injuries.
• When to See a Doctor: Seek medical attention if you experience severe pain, persistent bleeding, signs of infection, or any other concerning symptoms.

Addressing Concerns and Misconceptions

There are several common misconceptions about menstrual cups that can deter potential users. Let’s address some of them:

• Myth: The cup can get lost inside you.
  • Fact: The vagina is a closed cavity, so the cup cannot get lost inside you.
• Concern: Using menstrual cups with a tilted uterus or other anatomical variations.
  • Fact: Most women with tilted uteruses can use menstrual cups successfully. You may need to experiment with different cup shapes and insertion angles to find what works best for you.
• Reassurance: When used correctly, menstrual cups are a safe and effective menstrual product. It’s important to do your research, choose the right cup, and practice proper hygiene.

Conclusion

Menstrual cups are a popular alternative to traditional menstrual products for their sustainability and cost-effectiveness. While generally safe, it’s vital to be aware of potential side effects like discomfort, leaking, difficulty with insertion/removal, and the risk of infection. By choosing the right cup size and material, practicing proper hygiene, and consulting with a healthcare professional when needed, you can minimize risks and enjoy the many benefits of menstrual cup use.
