Levels of progesterone and estrogen
Estrogen and progesterone levels begin to increase prior to mensuration.
Blood levels of estrogen and progesterone decrease.
Menstruation is triggered by a drop in estrogen and progesterone levels, which signals the shedding of the uterine lining. This drop in hormone levels occurs when an egg released during ovulation is not fertilized. The decrease in hormone levels causes the blood vessels in the uterus to constrict, leading to the shedding of the uterine lining, resulting in menstruation.
The hormones that primarily regulate the menstrual cycle are estrogen and progesterone. Estrogen helps build up the uterine lining, while progesterone maintains it. Changes in the levels of these hormones throughout the menstrual cycle control ovulation and menstruation.
Two hormones responsible for the menstrual cycle are estrogen and progesterone. During menopause, the levels of estrogen and progesterone decrease, leading to the cessation of menstruation and other symptoms associated with menopause.

At the time of a woman's menstrual periods, estrogen and progesterone levels are high and may cause constipation. High levels of estrogen and progesterone during pregnancy also can cause constipation.
