Does a girl break her fast and stop praying if she sees blood 15 days after her purity, which followed a 6-day menstruation in Ramadan?

If blood appears fourteen days after the beginning of purity and continues for a day and a night, it is menstrual blood, necessitating breaking the fast and abstaining from prayer. This is based on the well-known view among the Hanbalis that the minimum period of purity is fourteen days.
