My wife and I came to Toronto from Israel last week on Thursday night, it was a long day of traveling and she forgot to take her birth control pill. Last night (Saturday night) she was supposed to go to the mikvah. Although Saturday morning she woke up to find blood and her period had started right at the end of her nida time. She obviously didnt go to the Mikvah last night due to the blood. Does she have to wait the full nida time (5 plus 7 days)? can she go to the mikvah after 5 days?
She has to start the seven days over, meaning to count seven clean days.
There is no need to count another five days, but if her period has begun, she will probably not be able to start counting “clean days” right away.
