What is considered a heavy flow?

First, let's understand what's considered a heavy flow. You may think you have a heavy flow because you change your tampon or pad every 2 to 3 hours, especially at the beginning of your cycle. But did you know that it's normal for a menstrual cycle's flow to be heavier during the first few days? So let's check some facts to put heavy flows into perspective:

But it's difficult to understand how much blood you're losing with a pad or tampon. Instead, with a menstrual cup, you'll know exactly how much blood you're losing because you'll know the cup's full capacity. And most cups come with fluid levels grooved into the cup’s silicone walls to see the amount of blood collected each time you empty your cup. 

But that same study found that heavy menstrual bleeding is more common than once thought. And it can wind up causing you fatigue and affecting your lifestyle. So if you suspect that you have a very heavy flow, consult your gynecologist or healthcare provider to rule out any underlying medical conditions.

Why a menstrual cup is good for a heavy flow

Apart from tracking blood loss, menstrual cups can make your period a much more pleasant experience and protect the environment. Here's how:

  • Fewer leaks: Wondering about tampon vs cup leaks? Since a menstrual cup creates a seal within your vagina, it shouldn't leak unless you're using the wrong size or the cup hasn't created a seal. New studies show cup leakage is the same or lower than tampons.
  • More freedom: You can lead an active lifestyle and run, swim, jump, and dance as much as you want. The right menstrual cup for heavy flow will stay in place.
  • Less waste, fewer worries: A period cup collects more blood than traditional period products. For example, the Ruby Cup Medium collects as much blood as 3-4 tampons. So you'll have fewer changes than sanitary pads or tampons because you can use a period cup longer before needing to empty it. 
  • Save money: Using a menstrual cup costs a fraction of what you would spend on pads and tampons.

Heavy flow menstrual cups: What should you look for?

Now that you know how a cup could change your life, here's what to look for when choosing a menstrual cup for a heavy flow:


  • Capacity: When you choose a cup that has ample capacity, you no longer have to run to the bathroom every 2 hours. We recommend emptying your cup no later than every 8 hours, but, for heavy flows, you may want to empty your cup every 4 to 6 hours. A cup with a minimum of 30ml should give you the peace of mind you need when you start using a cup until you understand how much blood you're losing per day.


03 Ruby Cup sizing chart for the best menstrual cups for heavy flow


  • Size: A menstrual cup works by creating a seal with your vaginal wall that allows the cup to stay in place to collect your period blood. So using the wrong size is the reason your cup will leak. To know the right size cup for you, know your cervix. For a high cervix, you might need a longer cup to create suction in your vaginal canal. If your cervix is lower, you might need a shorter or smaller cup. For greater peace of mind, use our sizing guide and our cervix-measuring guide to help you choose the right size cup for you:

  • Firmness: This is probably the most subjective of all. You'll need a cup that's not too soft or too firm because it needs to sit comfortably and imperceptibly inside your vagina.

  • Refund Policy: Let's be honest. Even with this information, you may not get the right cup on the first try. Because each body is unique, you might need a cup of a different size, shape, or firmness. So, whether you have a heavy flow or not, look for a cup with a flexible return policy.    


What about wide vaginas?

We know everyone's body is one of a kind. Even if you don't have a heavy flow, you may have a wide vagina, which means you'll need a bigger sized cup to prevent leaks, create suction, and keep the cup from sliding down.

To date, there aren't enough studies to understand what makes a vagina wider than another or what the average size of a vagina is. But we know that our Ruby Cup Medium is 45 mm wide, one of the widest cups on the market that can deal with even the heaviest of flows.

    Here are the most common questions answered about heavier flows, beginner cup users with heavier flows, and more. 

    How much blood do you lose during your period?

    Did you know that the average menstrual flow equals 35 ml? And a heavy flow is considered as 80 ml of menstrual fluid or more per menstruation. You may think you have a heavy period because you need to change your pads and tampons often. But using a menstrual cup helps understand how much blood you're actually losing every month.

    Are menstrual cups good for heavy flow?

    Menstrual cups are good for a heavy flow because they:

    • collect blood rather than absorbing it, leaving you feeling cleaner.
    • have a lower risk for Toxic Shock Syndrome than tampons.
    • have a higher capacity than pads or tampons.
    • let you lead an active lifestyle—you can swim, dance, or do handstands with a cup.
    • let you sleep leak-free.

    What is the best menstrual cup for heavy flow?

    The best menstrual cup for a heavy flow will be wider and have a bigger capacity than most cups. For example, Ruby Cup Medium can hold up to 34 ml of menstrual fluid and is 45 mm wide. But each body is different, so use this sizing guide to choose the best cup for you.

    What is the best menstrual cup for beginners with a heavy flow?

    The best menstrual cup for beginners with a heavy flow is one that has a bigger capacity than most cups. However, since it's your first time, use a sizing guide to help you choose. When in doubt, opt for a duo pack, like Ruby Cup's, so you can experiment with two sizes. 

    Which menstrual cup holds the most fluid?

    Currently, the menstrual cups that hold the most fluid are the ones with a higher fluid capacity. When you consider that a heavy flow equals 80 ml or more of blood loss per cycle, any cup with 30 ml of capacity or more can handle heavy periods.
