If you are concerned that performing your full usual set of bedikot may lead to extra halachic questions, you may perform fewer bedikot at this time.
Even now you must, at absolute minimum, perform a hefsek taharah and one bedikah each on days one and seven. If any of these three examinations are omitted, the seven clean days are not valid, so it’s crucial to remember the bedikah on day seven.
If at all possible, you should also do a bedikah on at least one intermediate day. This helps ensure that you don’t inadvertently go more than five days without a bedikah, which would invalidate the entire count and require you to start over.
In the event that you do nonetheless have a questionable bedikah, we recommend that you call the halachic authority to whom you usually bring such questions to consult. (You could also contact a Yoetzet Halacha through Nishmat’s Golda Koschitzky Hotline, or a local Yoetzet Halacha.) Explain that it is difficult to bring in the cloth because of social distancing, and give as many details about it as possible.
Another possibility is to seek to have it evaluated by a rabbi online through Tahor App (available on iPhone and some models of Android phones), which uses special color calibration technology to ensure that the stain is photographed and transmitted accurately. While some borderline colors will require in-person evaluation, many questions can be accurately assessed through the app.
If you will need to drop the bedikah off for in-person evaluation, lay it flat to dry and then place it in a clear plastic bag. Wash your hands and place the bag in an envelope with a note with your phone number and other relevant information.
Be”H, the pandemic will pass and we’ll be able to return to our normal mikveh practices soon!
