Is a small amount of blood, such as five or ten drops, that appears at the beginning of menstruation but does not continue, considered menstrual blood that necessitates abandoning prayer?

If a woman sees blood during a period when it could be menstruation, she is considered menstruating and must stop praying and refrain from all that a menstruating woman is forbidden from. If the blood continues for a little while and then becomes heavy, all of that is considered menstruation, and she must stop praying as soon as she sees the first drops of blood. However, if she sees purity before less than a day, this means she is not menstruating.
