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.
