Menstrual cups are one of the safest and most sustainable period products available today. They're reusable, comfortable and can be worn for up to 12 hours at a time. Like any product though, menstrual cup safety is important for your health and comfort.

Here are seven common menstrual cup mistakes to avoid.

1. Don't share your menstrual cup

A menstrual cup is a personal hygiene product and should only be used by one person. Even after washing or sterilising, sharing one can increase menstrual cup infection risk by transmitting bacteria, fungi and other infections. If someone else needs a menstrual cup, they should use one of their own.

2. Don't wear it for more than 12 hours

A menstrual cup should not be worn for longer than 12 hours, even on lighter flow days. Leaving it in for longer can lead to toxic shock syndrome. If you have a heavier flow, you may need to empty and rinse your cup more often to prevent your menstrual cup leaking.

3. Don't use a menstrual cup without consulting your doctor if you have an IUD

People with an intrauterine device (IUD) can often use a menstrual cup safely, but it is best to speak with your healthcare provider before making the switch.

During removal, pulling on the cup without releasing the suction seal first may put pressure on the IUD strings and increase the risk of displacement. Your doctor can advise you on whether a menstrual cup is suitable for you and how to use it safely. If you have an IUD and are considering switching to a menstrual cup, read our guide on using a menstrual cup with an IUD.

This small cup is not just a solution to your period care but is also a significant step towards maintaining a sustainable lifestyle.

4. Don't pull the cup out without breaking the seal

This is one of the most common menstrual cup removal tips. A menstrual cup creates a gentle seal inside the vagina to stay in place. Pulling without releasing it first can cause discomfort or make you feel like the menstrual cup is getting stuck. Instead, pinch the base of the cup to release the seal first, then gently wiggle it out. This makes removal easier and helps prevent discomfort.

5. Don't choose the wrong size

Menstrual cup sizing depends on several factors including your age, flow, cervical height, and pelvic floor strength. A cup that is too small may leak or move around. Getting your size right is one of the most important menstrual cup dos and don'ts. If you're unsure, our menstrual cup sizing guide can help you find the best fit.

6. Don't skip sterilising your cup

Your menstrual cup should be sterilised before using it for the first time and before each new cycle. Boiling the cup according to the manufacturer's instructions helps eliminate bacteria and keeps your menstrual cup hygiene. During your period, rinse or wash the cup before reinserting it. If you don't have access to a stove or are travelling, here's how you can sterilise a menstrual cup without boiling it.

7. Don't use a menstrual cup for postpartum bleeding

A menstrual cup should not be used to manage postpartum bleeding, also known as lochia. After childbirth, healthcare providers recommend avoiding internal menstrual products until your body has healed and you've been medically cleared. Using a menstrual cup too soon can increase the risk of infection and interfere with recovery.

The bottom line

A menstrual cup is safe, comfortable and convenient when used correctly. Following a few simple guidelines can help you avoid discomfort, reduce the risk of infection and get the most out of your cup.
