Why is my menstrual cup leaking?

PMS Leaking Woman experiencing troubles

Ever found yourself wanting to scream with frustration: ”why is my menstrual cup leaking now?”, after it had worked so fine during your last menstrual cycles? But just because your menstrual cup started leaking once, doesn’t mean it has to stay that way. There are a couple of reasons why your menstrual cup is leaking – and all of them can be solved. 

So, why is your menstrual cup leaking?

1. Your Ruby Cup didn’t open properly

This is one of the main reasons for a menstrual cup to start leaking. The menstrual cup will only work if it was able to pop open fully after insertion. Only then can the vacuum be formed and keep you protected.

Solution: Do the test! Once inserted, carefully try pulling the cup in a downward movement – if the vacuum has formed, it will only move a little and not be removable without you feeling the suction. You can also run your finger around the edge to see if there might still be a small crease, hindering the vacuum to form.

A good trick to get the cup to pop open easily is to slightly move it around in a downwards movement once you’ve inserted it, you will most likely feel it pop open at the latest then.

2. The cup was inserted too high

Solution: You don’t have to put the cup in very high – if the stem gets in your way or pokes you, you can always trim it. In that way you can let the cup sit deeper down in your vagina without any disturbances.

How to stop your menstrual cup from leaking

If you have a low cervix

During menstruation, your estrogen levels drop, releasing the cervix lower down into the vagina. Also, your cervix opens lightly or swells to permit the uterus lining and mucus to flow out easily. It’s common that during that time it might tilt a little to one side.

If that happens, the cervix might dip into the cup, taking away capacity and filling it up faster, leading to an overflow. This is likely to occur especially during the first day(s) of your period or if you have a very heavy period.

Solution: remember to empty your cup more frequently and/or try to go with a different size.

If you have a tilted cervix

Due to the angle of your cervix, you might have to check that your cervix is actually insidethe Ruby Cup. It can happen that the Ruby Cup may open next to the cervix instead of around it, letting the blood flow past the cup freely instead of getting collected in the cup.

Solution: run your finger around your cup and try to feel if the cervix is outside of it. If so, take the cup out and re-insert it.

Understanding even better
