I found a tiny bit of blood on a tampon…turns out I’m pregnant. Am I niddah?

14 January, 2024


I thought I was going to be getting my period and I had a long car ride, so I used a tampon just in case it came during the drive. Turns out I’m pregnant but had the tiniest (less than a gris) bit of red blood on the tampon. Does that make me nidah?


B’sha’ah tovah!

Yes, that does make you niddah. Any amount of blood found on something inserted internally, like a tampon, can make a woman niddah. The leniency for stains smaller than a gris applies only to stains found externally (learn more here).

For the future, if you want to use protection just in case your period comes, we recommend using a disposable pad. Since the pad is external, all the leniencies of stains would apply, and a small quantity of bleeding would not make you niddah.
