What is the best menstrual cup for heavy flow? There are many options out there, but finding the best menstrual cup for you can be a bit confusing.

In this article, you can find a selection of the best menstrual cups specifically designed for heavy flow.

Let’s jump right in!

6 menstrual cups for heavy flow

The Venus Cup comes in two sizes (small or large) and there is a very affordable Starter pack offer that contains both menstrual cup sizes.

This is because our cervix moves throughout our cycle, so it is possible that you feel more comfortable with a different size during certain days of your period.

Key points:

• The Venus Cup can hold approximately 30% more than the average large-sized menstrual cup – equal to 9 regular absorbency tampons.
• The cup should last you at least 10 years.
• You can get a full refund if the cup isn’t comfortable after 2-3 periods (90 days guarantee).
• The cup has an invisible secondary rim with a slightly thicker silicone. There is also an inner ring for reinforcement. These features will help the cup to open after the fold is released.
• Their big size is the largest capacity menstrual cup on this list.

FAQ

Are menstrual cups good for heavy flow? 

Menstrual cups are suitable and work perfectly, even if your flow is heavy. 

Another thing is that tampons or pads sometimes make it look like your period is very heavy, but once you switch to a cup, you might notice that your flow isn’t as heavy as you think. 

In any case, larger menstrual cups can hold up to 9 regular absorbency tampons. 

Which menstrual cup has the largest capacity?

The large Venus Cup has a capacity of 47ml to the cup’s rim. This equals about 9 regular absorbency tampons. The second one is the MeLuna Cup, holding up to 42ml. 

How much can a period cup hold?

The larger menstrual cups can hold between 41-47 ml of liquid. To put this into perspective, a super tampon or a pad can hold up to 12-15 ml. That means a larger menstrual cup can hold about three times the amount of a super-absorbent tampon or pad. 

How often should you fill a menstrual cup?

This entirely depends on your flow. If you worry about overflowing, empty it once every 4-6 hours (or 2-4 times per day), especially on the first days of your period.

This will help you see how full the cup is and know if you can keep it longer. You should never keep the cup for more than 12 hours.

Is it normal to fill a menstrual cup in 2 hours?

Most menstrual cups offer between 6-12 hours of coverage. However, it strongly depends on your flow. Try sizing up if you must empty a full cup every 2 hours. 

If this doesn’t solve the problem, your flow is way heavier than average, and you should make an appointment with your gynecologist to figure out what’s happening.

What happens if my menstrual cup overflows?

If your periods are very heavy and you have a smaller cup size, you might experience leaking. You can size up or empty the cup every couple of hours to prevent overflow. 

Why am I bleeding through my menstrual cup?

It might be because the cup hasn’t fully unfolded. Once you insert it, you must ensure the cup opens, creating suctions and preventing leaks. You may have to downsize if it can’t open fully after many trials. There are several ways to see if the cup is open – you can find more about that here.

Conclusion

To summarize, many options and menstrual cups exist, even if you have a heavy flow! 

While getting a cup that’s the wrong size and doesn’t fit can be annoying, it is worth it to keep looking for the one that will suit you the best. 

If you do some extra research beforehand, measure your cervix, and figure out what type of cup would be best for you, you will find the perfect cup on the first try.
