Why do I have my period
The shedding of endometrium is periodic, once a month, and is influenced by the cyclical changes in ovarian endocrine. After each shedding of the endometrium, follicles in the ovary begin to develop. Under the influence of secreted estrogen, the endometrium, including epithelial cells, blood vessels, and glands, begins to grow and thicken again. This is called the proliferative phase of the endometrium.
Around the middle of the menstrual cycle, specifically 14 days before the next menstrual period. The follicles in the ovary ovulate (taking the 28 day cycle as an example, the 14th day is the ovulation day). After ovulation, follicles form the corpus luteum, which can secrete estrogen and progesterone. These hormones act on the endometrium, causing it to become thicker, blood vessels to bend and become congested, glands to become thicker and expand, and secrete many nutrients. This stage of the endometrium is called the secretory phase.
