What is the ruling on discharge mixed with blood, and must one pray, bearing in mind a previous miscarriage?

Blood mixed with discharge:

- If it is before the completion of the usual days of menstruation, then it is part of the remaining menstruation and has its rulings.

- If it is after the completion of the usual days and confirmation of purity (by the white discharge or dryness), then it is dysfunctional blood due to an ailment, and it does not prevent prayer, fasting, or intercourse, because the minimum period of purity between two menstruations is fifteen days.
