1. If you do not experience an actual flow, you may take precautions against becoming
niddah from any staining by wearing colored underwear and waiting at least a few seconds (ideally 15 seconds) after urinating before wiping. This way you may disregard stains found on your underwear or on
toilet paper. Should you find stains larger than a
gris (the size of a US dime or Israeli shekel) on a white garment, or multiple stains that are cumulatively larger than a
gris on your skin, you still may be rendered
niddah. Additionally, if you see blood exit your body (while you are on the toilet or in the shower, etc.) you would be rendered
niddah. Please see our pages on
stains and
toilet paper for more details.
You should not perform any
bedikot unless it is required (e.g., on an
onah day).
2. It can be difficult to distinguish between staining and a flow. There are no set limits for length of staining or specific amounts that would render you
niddah. As a general rule of thumb, bleeding that could be contained by a pantiliner would be considered staining. Bleeding that requires stronger protection, like a pad, would be considered a flow. Please see our page on
stains for additional discussion.
On your
onah days (
haflagah,
yom hachodesh, and
onah beinonit based on your last period), you are required to perform a
bedikah, which may render you
niddah.
3. You may inspect your black underwear to see what is going on with your body. You may also wear colored underwear that isn’t black, which could be easier to evaluate. Or you could use disposable pantiliners; a stain on a
disposable pantiliner would not make you
niddah. Additionally, if you waited at least a few seconds after urinating before wiping, you may examine the toilet paper.
Please feel free to get back to us with any further questions.
B’Hatzlacha!
