Sometimes though, menstruation either never starts which is called primary amenorrhea or suddenly stops in a person who's previously menstruating which is called secondary amenorrhea.
It can be primary, in which case menstruation never started, or secondary, in which case regular menstruation has stopped in a female who was previously menstruating.
Second, salat, or ritual prayer five times a day—at dawn, noon, afternoon, sunset, and late evening—which are obligatory unless you haven’t hit puberty, are too sick, or are menstruating.
