If I fell ill on the seventh day of the seven clean days and only did one bedikah in the morning, do I have to do another bedika if I am better on the ninth day since usually you do not continue bedikot if you delay the mikva when you are ill?
Answer
Since you did manage to do one valid bedikah on the seventh day, you completed the bedikot required for the clean days. You need not add a bedikah just because the mikveh immersion was delayed.
