Not sure how to use a menstrual cup? This simple guide will provide the basics, plus a few tips and tricks to help you succeed with menstrual cup wearing.

The Basics of a Menstrual Cup

A menstrual cup is a reusable tampon alternative that collects menstrual fluid rather than absorbing it.

A cup is worn inside the vaginal canal and it sits below your cervix (the base of your uterus and the thing that dilates to allow a baby to exit during birth.) During menstruation menstrual fluid exits your uterus (sloughs off the lining inside) through the cervix.

When you wear a tampon the fluid is absorbed. When you wear a pad the blood exits the vagina and is absorbed by the pad in your underwear. When you wear a menstrual cup the fluid is collected inside until you remove the cup and empty it.

Menstrual cups can be worn for up to 12 hours at a time. The actual wear time will vary for each person, but generally speaking if you have an average flow you will be able to wear a menstrual cup the full 12 hours. If your flow is heavier you will need to change more frequently.

How to Insert Your Menstrual Cup

To insert your menstrual cup you will want to fold it first. There are many menstrual cup fold styles, but the easiest for a beginner is the "punch down fold" shown below.

It can take practice to get your menstrual cup to fold and stay folded, so keep playing with it until you feel comfortable. 

Once folded, it's time to insert the cup. This can be done when you're not on your period if you want to practice. 

While inserting your cup, you will want to try and keep it folded as long as you can until it's fairly high in the vaginal canal. If it opens too soon you can still try to wiggle it to the correct position, but if this doesn't work remove it and try again. Remember, this is a new thing! Mistakes will happen but you will get better with practice.

The cup should fit inside without anything sticking out of you, including the stem if there is one. If the stem sticks out you will want to remove the cup and trim it to a comfortable length. 

For you to be successful with your cup it needs to be fully opened and sealed against the vaginal walls. To make sure this has happened you can insert a finger and run around the cup walls to check for dents. To help it open fully you can try pushing the base or pushing the vaginal walls out to allow it to open fully.

Is it a good fit?

If your cup can't be felt, stays in place, and doesn't leak you have a winner! This may only happen after some trial and error. Most cup users take 1-3 cycles to get things going how they should be. You may want to wear backup liners or period underwear until you know it's going well.

How to Remove Your Menstrual Cup

Removing a menstrual cup can be pretty simple, though it is a scary thought at first! You can try removing your cup for the first time while you're in the shower to reduce your worry about a mess.

First, relax! Again, fear and worry will tense up your muscles making it harder to remove your cup. 

You must break your cup's seal before removing. The stem is not to be pulled on as a removal device, it's just to find the cup! Pinch the base of the cup to break the seal. If it's too high inside, bear down using your vaginal muscles until it's low enough, then pinch the base and break the suction. If you have an IUD in place it's especially important to be sure your strings are not in the way and you aren't grabbing them. 

Gently wiggle down the cup and once it's out of your body, keep a firm grip with your pinched fingers on the base and keep the cup upright. If over a toilet, tip over and dump the contents. If in the shower, bend down towards your drain and dump the contents low towards the drain.

Once removed, you should wash your menstrual cup with warm water and a cup safe cleanser (if desired) and re-insert.

Tips for Menstrual Cup Success (or, ahem... Period Nirvana)

1. While inserting your cup, push against it with your vaginal muscles (like you're pooping) while pushing it in. Release the muscles when the cup is in the highest position. This gives it extra security to keep it in place.

2. "Burp" your cup after inserting it by pressing the base and releasing air. This can help it open.

3. Bubbles = Trouble! If you feel bubbles it means your cup may be full and it's time to remove it before you have a leak.

4. Cup too soft? Run it under cold water to stiffen the silicone before you insert it. Firmer cups open easier and are easier to insert. 

5. Cup too firm? Run it under hot water to soften the silicone before inserting. Check the temperature before inserting to make sure it doesn't burn the skin.

Menstrual Disc Size FAQ

Which size menstrual disc should I pick? Disc sizing is determined by your cervix height. Not sure where your cervix is located? Watch your  How to Measure Your Cervix  guide.

One Size Fits Most | Regular sizes will fit almost everyone with the exception of people with a low cervix. If you have a high cervix you can wear a One Size menstrual disc but consider one with a removal loop or tail.

Medium | Small | Short sizes are meant for lower than average or very low cervix heights. Sizes Small or Short are very small diameter options and should only be used if you have a low cervix. 

Consider taking the  Period Nirvana Quiz  when choosing your menstrual disc to be matched with the style and size most likely to work for you.

Menstrual Cup Size FAQ

Menstrual cup sizing refers only to the cup's rim diameter, and to pick the size best for you the determining factors are based on your age and pregnancy history (primarily.) Other fit factors include your cervix height and the shape/firmness of the cup. It can be tough to find the perfect fit on your first try; let us take the guesswork out of the process by taking our menstrual cup quiz.

Teen | Mini | 0 | XS sizes are best for first time users, and geared toward teens. These have the smallest diameter.

Small | Medium | A | 1 sizes are best for first time users who are under 30 and haven't had a full term pregnancy. This is a general guideline and not a rule - exceptions to consider would be if you are very active or have a hypertonic pelvic floor. These sizes have a smaller diameter.

Large | Regular | B | 2 sizes are best for users who are over 30 and/or anyone who has had a full term pregnancy. These sizes have a larger diameter to stay in place when pelvic floor muscle tone is more lax. 

Other factors to consider for cup sizing include the length (corresponding to your cervix height), shape, and firmness. We suggest taking the Period Nirvana Quiz for help selecting the right size/shape/firmness for your unique anatomy.
