Tissue from uterine lining on bedikot

17 January, 2017


I have an IUD and at the end of my period after I have stopped bleeding, I continue to expel some tissue from the uterine lining. It is clearly lining and not blood. Since the badim are not white during this time, I always push off starting the 7 nekim. Since this is lining and not blood, can I start counting during this time, or must I still wait till i get a fully clean bedika?


Tissue from the uterine lining does make a woman niddah, just like blood.  However, it is possible that the color of the tissue you are describing is not a niddah color, in which case it would not push off the clean days.  

We recommend soaking in a bath as part of the cleaning prior to making a hefsek taharah, so that there is less chance of having old blood interfere with the clean days.  We also recommend, in your case, that you make early attempts at a hefsek taharah and bring the cloths for evaluation, in case the color is indeed acceptable. Even some browns can be accepted on a hefsek taharah!  If you'd like to share your location with us, we can try to make a referral to a local halachic authority.
