Menstruation, an uncertain thing, generally has no effect on the result of fortune telling. Fortune-telling needs calculation, and everything is certain. Because a person's fate is fixed, fortune-telling can't be considered marriage.
Marriage generally refers to the long-term voluntary union of men and women of marriageable age in the name of husband and wife in terms of economic life and spiritual material. The relationship between husband and wife based on physical condition, working ability, marriage view, history and culture should be recognized by medicine, ethics and civil law, and it is a social phenomenon that they can produce and live together and form a family in the name of husband and wife.
