Menstruation comes from there

In our lives, many women do not have a comprehensive understanding of their own physiological knowledge. For example, for girls who have just entered puberty, most people will be particularly panicked when they just get their period, because they don’t know what’s going on. They will find that their lower body is bleeding, and some people even think they have a terminal illness. So where does the menstruation come from?

Menstruation is of course the outflow from the uterus, it is produced by the transformation of the endometrium. It may be that your menstruation is not completely clean, and there is a little blood when you exert force during defecation. If you are not pregnant, your menstruation will come at a normal time.

Menstruation is vaginal bleeding caused by the periodic shedding of the endometrium due to cyclical changes in ovarian hormones. After puberty, the ovaries gradually develop under the stimulation of gonadotropin secreted by the hypothalamus-pituitary gland. Under the action of pituitary follicle-stimulating hormone, the follicles gradually grow, mature, and secrete large amounts of estrogen. Under the action of estrogen, the endometrium proliferates and thickens, showing proliferative changes. Under the action of luteinizing hormone, the mature follicle ruptures and discharges the egg. After ovulation, the follicle forms a corpus luteum, and the luteal cells secrete progesterone. Under the combined action of estrogen and progesterone, the endometrium further proliferates and shows secretory phase changes due to the secretion of its glandular epithelial cells. If the egg is not fertilized, the corpus luteum begins to shrink. The average lifespan of the corpus luteum is 14 days. After the corpus luteum atrophies, the levels of ovarian estrogen and progesterone drop rapidly, causing the endometrium to lose support and atrophy, and also fall off due to ischemia and necrosis, resulting in vaginal bleeding, which is commonly known as menstruation. However, in clinical practice, uterine bleeding without ovulation is common, which is called anovulatory menstruation.

Menstruation is also known as monthly affairs, monthly water, monthly letter, period, seeing red, etc. It is called menstruation because it occurs once a month for most people. It refers to regular, cyclical uterine bleeding. Strictly speaking, this bleeding should be accompanied by ovarian follicle maturation, ovulation and corpus luteum formation, and the endometrium should undergo changes from proliferation to secretion. However, in clinical practice, uterine bleeding without ovulation is common, which is called anovulatory menstruation.

Menstruation will be discharged from the vagina, so your bloody stool may be caused by a mild anal fissure with blood due to internal heat.

Irregular menstruation and light brown color indicate that there is congestion during menstruation, that is, slight blood stasis. Clinically, it is caused by irregular menstruation, which is normal for you. This condition is also common in women with normal or regular menstruation. It generally does not require treatment as the uterus has the ability to repair itself. Menstruation is the periodic shedding of the endometrium in a woman's uterus, which flows out of the uterus through the vagina. The vagina and urethra are adjacent, and blood often remains at the urethral opening
