Is a light flow on Mirena a period?

28 December, 2016


I'm in my 4th year on Mirena. Recently I started getting a dark brown flow/discharge for 4–5 days. It's light enough for a pantyliner. Is this considered a period to render me niddah?

Thanks for your help in clarifying this issue.


A discharge that is light enough that a pantyliner is sufficient (as opposed to one that requires a pad or tampon to contain the bleeding) is likely considered staining rather than a flow. This is true even if it continues for a few days.

Therefore, you may take precautions against becoming niddah from this staining by wearing colored underwear (or disposable pantyliners) and waiting 15 seconds after urinating before wiping.

We also advise abstaining from intercourse until 24 hours after the staining subsides so your status may be fully clarified.

Please note that if the staining becomes heavier (comparable to a period), and is a niddah color, it will render you niddah. So too, if you find a stain larger than a gris (the size of a US dime or Israeli shekel) on your skin or on a white garment, it may render you niddah depending on its color.

Please feel free to get back to us with any further questions.
