If there is good reason to suspect that local authorities are weighing closure of the mikveh, or that you or your husband are at risk of quarantine, then you should attempt to perform an early
hefsek taharah on
day four, as well as a thorough
bedikah on day five. That way, should closure on short notice remain a concern, you will be able to immerse a night earlier than you ordinarily would, based on the early
hefsek taharah (and counting the
bedikah the next day as the first
bedikah of the
clean days). If the concern fades, then you will immerse on your usual schedule.
As you go through the clean days, you should keep two counts in mind: one based on the early
hefsek taharah, and one based on the regular schedule with the day five
bedikah counting as your
hefsek.
If you typically perform a reduced number of
bedikot, please consult with us to confirm how best to adjust your practice to this scenario.
