What Happens During Menstruation

Menstruation is the shedding of the uterine lining when pregnancy doesn’t occur.
It marks the start of a new reproductive cycle.
Blood and tissue flow out through the vagina for 3–7 days on average.
Hormone levels drop sharply before menstruation begins.
Cramps happen as the uterus contracts to expel the lining.
It’s a normal, healthy sign that the body’s system is working.
Stress, diet, or hormonal imbalance can affect timing and flow.
Each period resets the body for another chance at conception.
The color and texture of menstrual flow can reveal hormone health.
Menstruation connects the physical cycle to the rhythm of fertility.
