The Status in Question
In the laws of family purity, niddah is a specific halachic status of a woman associated with restrictions on marital intimacy. Shulchan Aruch begins this section with rules concerning blood originating in the uterus. The circumstances defined by halachah matter in determining whether this status arises; the everyday description “I noticed something” alone is not enough to assess every case. [1]
Ketamim—discovered stains—are considered separately. Their laws were established by the Sages and have their own conditions. It is therefore important to report precisely whether there was bleeding or a discovered stain, where it was found, and under what circumstances it appeared. These details help formulate the right question without confusing different cases. [2]
Marital Boundaries
When niddah status is established, spouses refrain from sexual intimacy and observe harchakot—rules of separation in everyday life. These include restrictions on touching and passing objects directly from hand to hand. These rules remain in effect during the seven clean days as well. [3]
Knowing the general rules makes life together easier: you can agree in advance on how to pass objects and arrange sleeping and everyday tasks. Explaining your situation to your spouse, making calm requests, and paying attention to each other's fatigue help maintain clarity. Both spouses' participation is especially important when the usual routine needs to change.
How This Period Ends
Rambam describes the accepted practice: after bleeding that prohibits marital intimacy has stopped, seven clean days are counted, followed by immersion. Beginning the count requires a hefsek taharah—the appropriate check; its procedure and permissible day are discussed separately. The seven clean days are not the same as seven days that have simply elapsed since menstruation began. [4] [5]
Even a prolonged cessation of bleeding does not in itself end niddah status. Rambam explicitly states that the passage of time does not replace the prescribed immersion in a suitable mikveh. It is therefore helpful to distinguish in your personal records between the beginning of bleeding, the hefsek, the days of checks, and the completed immersion: these are different stages of the same process. [6]
Where Prayer and Everyday Life Fit In
The term ritual impurity should be understood in its halachic sense. It is not a judgment of a woman's character or human dignity. Rambam rules that ritual impurity in itself does not prevent prayer: the relevant general requirements for preparation apply to it. [7]
If it is unclear whether niddah status has arisen, how to assess a stain, or whether the count may begin, the answer depends on the specific circumstances and the accepted custom. Recorded dates and a precise description of the situation make it possible to consult a rabbi who deals with the laws of family purity and receive an answer to your own particular question.
