Small removable circles on moch

15 November, 2023


I did a hefsek tahara and it came out clear. The moch dachuk came out clear but had 2 little brownish circles/balls that were able to be picked up and removed (once removed the moch was clear). I wasn’t sure if that was ok so I repeated the process the next day (another hefsek and another moch) and the same thing happened, where the hefsek tahara was clear and the moch had 2 little brownish circles/balls that were able to be removed and again left no residue. Is that old blood that for some reason has not been washed away? How would I proceed? Thank you!


A light brown (like the color of coffee with milk or lighter) with no reddish tint is not a niddah color. It would not invalidate a moch dachuk, or any bedikah.

Additionally, we follow the halachic position that anything that can be easily removed and doesn’t leave a residue does not invalidate a moch or bedikah, regardless of color. Therefore, the first hefsek and moch you did are valid. The second hefsek, which you did the next day, counts as the bedikah of the first day of the seven clean days.

It’s possible there is some leftover blood or discharge in your vaginal canal that the moch dachuk caught. In the future, we recommend cleaning yourself out gently, either by soaking in a warm bath or using water or a wet cloth cloth at least fifteen minutes before doing the hefsek to remove any leftover blood.
