What is Normal period length and menstrual flow?

In women, period occurs due to regular cyclic shredding of the endometrium covering the uterus. This is due to hormonal changes that occur during the menstrual cycle.

Before ovulation, estrogen is the dominant type of hormone produced by the growing follicles. However, after ovulation, the ruptured follicle forms the corpus luteum which increases production of progesterone.

If your egg released is not fertilized and implanted into the uterus, it causes the corpus luteum to breakdown. This will result to decreased hormones and shredding of your endometrium as period.
