Found thread after mikveh

7 January, 2021


When getting dressed after the mikva, I noticed a brown thread on my arm that seemed the same colour as my towel. I only put the towel over me after tevilla. Nothing to worry about, is there?

Am I the only one who works hard to prepare but then afterward feels so frustrated that these things happpen?

If it was on me for some unbeknown reason it surely would have floated off in the mikva.

I’m undergoing ivf so am extra stressed.

Thank you


Based on your description, that you saw what looked like a brown thread from the towel after tevilah, there is no cause for halachic concern.

There are many women like you, who find themselves frustrated and worried by concerns that they have found something that invalidated their immersion. In many cases there is no halachic cause for concern, since common sense explanations such as you provide can be relied on. Additionally, the halachot regarding preparation for mikveh already build in a number of stringencies, so that a woman who makes a real effort to prepare for immersion will generally have one that is valid.

All that being said, if you find these concerns recurring month after month, you might benefit from speaking with a counselor who can help you learn to cope with them. It is understandable that IVF has created real stress for you. That is something else with which a professional may be able to help. Referrals to religious therapists can be found at or
