Is there an issue of dam chimud for a woman who is mesulekes damim? Can a 50-year-old woman get married without the seven day waiting period?
The halachah of waiting seven days before getting married applies at every age — even fifty and up. Seven ‘clean days’ must be counted, after which the lady immerses, with a berachah.
