Why do you bleed during your period?

Menstruation or period, refers to the shedding of the inner lining of the uterus (the endometrium) and the discharge of blood and other materials through the vagina. Here's why you bleed during your period:

1. Menstrual Cycle: During a woman's menstrual cycle, the ovaries release eggs (ovulation). If the egg is not fertilized, the levels of the hormones progesterone and estrogen decrease. This drop in hormone levels signals the uterus to shed its lining, as it is no longer needed to support a potential pregnancy.

2. Breakdown of the Endometrium: As the hormone levels decline, the blood vessels in the endometrium constrict, cutting off the blood supply to this uterine lining. This causes the endometrium to break down and be released into the uterine cavity.

3. Shedding of the Endometrial Lining: The broken-down endometrium, along with blood and mucus, forms a menstrual flow. This flow passes through the cervix and is discharged from the vagina during the period.

4. Menstrual Bleeding: The shedding of the endometrium and the release of menstrual flow results in vaginal bleeding during your period. The duration and heaviness of the bleeding can vary from woman to woman and from cycle to cycle.

It is important to note that excessive bleeding or other unusual symptoms during menstruation should be discussed with a healthcare professional to rule out any underlying medical conditions.
