Menstruation lasting for 3-7 days is normal.
Healthy women menstruate once every month, which is known as menstruation. Due to the different physical conditions of each woman, the onset of menstruation varies. Some women have menstrual periods of only three days, while others may last up to seven days. The ovaries of women secrete estrogen, and under the influence of these hormones, the endometrium undergoes changes and sheds once a month, which forms menstruation.
