Question:
If my wife's mikvah night is on the night of Ohr Zarua for Ona Beinonis, does she go to the mikvah?
Answer:
She should go to the mikva and she is muter even though it is the time of the Ohr Zarua, because even those who are makpid on the Ohr Zarua, it is not on the mikva night.
Best wishes
