When Should I Empty My Menstrual Cup?
If you’ve switched to using a menstrual cup (or are thinking about it), one of the most common questions is: how often do I need to empty it? The short answer is:
👉 Every 4 to 12 hours, depending on your flow.
Let’s break it down:
⏰ General Rule: Every 8–12 Hours
Most menstrual cup manufacturers — and gynecologists — recommend that you empty and rinse your cup every 8 to 12 hours. This means for most people, you’ll need to do it:
-
Once in the morning
-
Once again before bed
This schedule keeps things hygienic and prevents leaks.
🩸 On Heavy Flow Days: Every 4–6 Hours
If you have a heavier flow, you may need to empty your cup more often:
-
Every 4–6 hours is typical on day 1 or 2 of your period.
-
You might fill the cup faster than you expect, especially if you’ve never tracked your flow volume before.
⚠️ Tip: If your cup is leaking, it’s probably full — or not inserted correctly. Try checking the cup sooner next time to see how quickly it fills.
🛏 Can I Wear It Overnight?
Yes — menstrual cups are safe for overnight use, as long as you don’t exceed 12 hours. They are a great alternative to pads or tampons for uninterrupted sleep.
🧽 How to Empty and Clean It Properly
-
Wash your hands thoroughly.
-
Remove the cup by gently pinching the base to break the seal.
-
Empty the contents into the toilet.
-
Rinse with cold water (to avoid staining), then warm water and mild soap.
-
Reinsert and go about your day!
👉 Don’t forget to boil your cup at the end of your cycle to sanitize it completely.
🧪 How Much Blood Does a Menstrual Cup Hold?
-
Most standard cups hold 20–30 ml of fluid.
-
For reference: A regular tampon holds about 5 ml, and a super tampon about 10 ml.
-
This means you may not need to empty a cup as often as you’d change a tampon.
