Try One of These Menstrual Cups for Heavy Periods

If you have a heavy period, the thought of one little cup catching your flow can be a tad hard to believe - but would you believe that there are some larger capacity menstrual cups that can hold as much fluid as 2-3 super plus tampons?!

One of the benefits of menstrual cups is that they can allow you to go a full 8 hours before needing to be removed and emptied (cue happy tears), and many people report that using a cup allows them to forget that they’re even on their period at all. But for those with a heavy flow, finding a menstrual cup that has a high enough capacity to allow them to go anywhere close to 8 hours before needing to empty their cup can be a challenge. But don’t worry - there are larger capacity cups on the market that will help those with heavy periods find more freedom and fewer bathroom breaks. And we’ve done our very best to track down some of the best high capacity menstrual cups for heavy periods at Period Shop.

How much do you actually bleed during your period?

It’s worth mentioning first up that a lot of us who are used to only using tampons and pads don’t truly know how much fluid we lose during our period. This is because tampons and pads absorb our flow so well that it’s impossible to get a good reading of just how much we lose. A lot of people are surprised to learn that they actually bleed less than they thought when switching to a cup! And keep in mind that the average menstrual cup holds more fluid than two super tampons, which usually hold around 10ml each.

The average person loses between 30ml and 45ml (equal to 2-3 tablespoons) of fluid during their entire period, and anything over 80ml is considered a heavy flow. If you have to change your ‘regular’ pad or tampon more than every 2 hours, it’s most likely you have what is deemed to be a heavy flow.

It’s also important to note that if you have excessive heavy bleeding (soaking a pad or tampon in an hour or less) you should always get it checked by a doctor to rule out any underlying health issues. Very heavy periods can be caused by anything from stress to endometriosis, PCOS, thyroid issues and more - so always discuss and investigate further with your doctor. 

The best menstrual cups for heavy periods

If you have a heavy period, our biggest tip for making it more comfortable and a whole lot more convenient is to choose a high capacity menstrual cup. The higher the capacity, the closer you’ll be able to get to that magical convenience of emptying your cup every 8 hours!

Depending on the brand, size or model number, all menstrual cups hold varying amounts of fluid. Here are our top picks for high capacity menstrual cups to suit a heavy flow:

Super Jennie Menstrual Cup

The Super Jennie Model 2 is one of our favourite higher capacity cups! It holds an impressive 41ml of fluid to the rim. This is a softer cup with a short rounded stem, so is suitable for those with sensitive bodies, or if you tend to experience period pain or cramping.

Pelvi Menstrual Cup

The Large size Pelvi Cup holds up to 40ml of fluid, falling just slightly short of the Super Jennie. We love that Pelvi is an Australian owned brand and their cups are made from extra-soft silicone, making them another good option for those with sensitive bodies. The stem is short and rounded, similar to the Super Jennie, and can’t be trimmed.

Canack Menstrual Cup

The Large Canack Cup is a great option if you’re on a budget (coming in at $25.95), and it holds up to 38ml

Merula Cups

Merula cups are well known for their larger capacities - the standard One Size model holds 38ml, while the Merula XL holds a massive 50ml! Merula menstrual cups have a unique ladder stem that is easy to trim if you have a low cervix

Intimina Ziggy Cup

The Ziggy Cup by Intimina is a bit different to the other cups we’ve mentioned, because it’s actually a menstrual disc - meaning it’s made from a thinner, softer and more flexible silicone and has a flat fit design. And the best part? It can hold up to a whopping 76ml of fluid! Keep in mind that due to the flexible nature of the Ziggy Cup, the capacity may decrease depending on the shape of your body and how the cup is positioned. Extra bonus: the Ziggy Cup can also be worn during sex! High fives all round. 

Preventing menstrual cup leaks with a heavy flow

Dealing with heavy periods can be challenging, but we’ve got you covered! The best combo we’ve found for managing a heavy flow is to choose a high capacity menstrual cup, and pair it with some absorbent period underwear to catch any overflow or leaking. It’s like a match made in period heaven.
