Shivah Nekiyim
Shivah Nekiyim are seven consecutive days that begin after a valid Hefsek Taharah An organized calendar helps show where each day falls in the sequence and what comes next
Shivah Nekiyim are seven days following a valid Hefsek Taharah No numbered days appear before that report, or beyond day seven An unsuccessful check alone does not interrupt the sequence; a confirmed invalidation requires a new valid report
Reports about checks and completion update the process only They are not new source events for Veset Hachodesh, Haflagah or days 30 and 31
