Is blood that appeared one day before the regular period and then stopped considered menstrual blood or irregular bleeding, and must the prayers that were abandoned based on it be made up?

If a woman sees blood one day before her usual period, it is considered menstruation as long as it occurs within the possible time frame for menstruation. She should stop praying, fasting, and abstain from everything a menstruating woman abstains from. She is not required to make up the missed prayers. She does not become pure until she sees a sign of purity (either dryness or white discharge). The minimum duration for menstruation, according to the majority of scholars, is one day and one night, while according to the Malikis, it is a single discharge, and their opinion is more cautious.
