Q. Due to their strained relationship, a wife refrained from going to the Mikvah. After 5-6 years, the couple made peace and returned to happily being married. When the wife returns to the Mikvah and the couple resumes marital relations, must the couple observe a separation period of 4+7 days and should she reimmerse in the Mikvah, as they did after their wedding night, because of a ch’shash for Dam Chimud?

A. Shulchan Aruch (Y.D. 192: 5) rules that one who remarries his divorcee, should wait seven days after establishing the date of the wedding as the law of dam chimud (menstruation caused by desire)applies.
The separation of four and seven days applies only when marrying a besula (virgin), which is obviously not the case here.
Horav Shlomo Miller’s Shlit’a opinion is that one should be stringent in an extended separation case and apply the dam chimud separation, as one would do with a machzir gerushoso (remarrying one’s divorcee) case.
