Menstruation
Menstruation is the routine discharge, or release, of blood and mucosal tissue from the uterus. This process occurs about once a month from the time a female reaches puberty until menopause. During pregnancy, the monthly menstrual cycle is absent while the womb nourishes the growing fetus.

What does two weeks early light menstruation mean?
It is possible that this isn't menstruation at all. Light bleeding mid-cycle may be ovulation bleeding or hormonal imbalances causing spotting. If it's a one-off then it's nothing to be concerned about, but if this occurs on a regular basis it is best to talk to your doctor about investigating the cause.
What is human menstrual cycle?
The menstrual cycle is the scientific term for the physiological changes that can occur in fertile women for the purpose of sexual reproduction and fertilization. This article focuses on the human menstrual cycle.
The menstrual cycle, under the control of the endocrine system, is necessary for reproduction. It is commonly divided into three phases: the follicular phase, ovulation, and the luteal phase; although some sources use a different set of phases: menstruation, proliferative phase, and secretory phase.[1] Menstrual cycles are counted from the first day of menstrual bleeding. Hormonal contraception interferes with the normal hormonal changes with the aim of preventing reproduction.
Stimulated by gradually increasing amounts of estrogen in the follicular phase, discharges of blood (menses) slow then stop, and thelining of the uterus thickens. Follicles in the ovary begin developing under the influence of a complex interplay of hormones, and after several days one or occasionally two become dominant (non-dominant follicles atrophy and die). Approximately mid-cycle, 24-36 hours after the Luteinizing Hormone (LH) surges, the dominant follicle releases an ovum, or egg in an event called ovulation. After ovulation, the egg only lives for 24 hours or less without fertilization while the remains of the dominant follicle in the ovary become a corpus luteum; this body has a primary function of producing large amounts of progesterone. Under the influence of progesterone, the endometrium (uterine lining) changes to prepare for potential implantation of an embryo to establish a pregnancy. If implantation does not occur within approximately two weeks, the corpus luteum will involute, causing sharp drops in levels of both progesterone and estrogen. These hormone drops cause the uterus to shed its lining and egg in a process termed menstruation.
In the menstrual cycle, changes occur in the female reproductive system as well as other systems (which lead to breast tenderness ormood changes, for example). A woman's first menstruation is termed menarche, and occurs typically around age 12-13. The average age of menarche is about 12.5 years in the United States,[2] 12.72 in Canada,[3] 12.9 in the UK[4] and 13.06 ± 0.10 years in Iceland.[5]The end of a woman's reproductive phase is called the menopause, which commonly occurs somewhere between the ages of 45 and 55.
When a girl is on her period does some of her eggs come out and they can be seen?
No, when a woman is on her period eggs do not come out. Ovulation occurs two weeks before menstruation, typically only one egg is released, if the egg is not fertilized it is reabsorbed into the body within the fallopian tubes. Menstrual flow does not contain any eggs.
Is luteinizing hormone produced only during the luteal phase of the menstrual cycle?
No, luteinizing hormone (LH) is not produced only during the luteal phase of the menstrual cycle. LH is one of the hormones responsible for ovulation, and its surge triggers the release of the egg from the ovary. While LH levels are highest right before ovulation, they are also present during other phases of the menstrual cycle.
Will you have a period every month when you have only one ovary and fallopian tube?
If the remaining ovary is healthy, yes, you will likely still have a period every month. The ovary is responsible for releasing eggs and producing hormones that regulate the menstrual cycle. The presence of one functioning ovary can usually sustain normal menstrual patterns.

Can your eggs be fertilized when your on your period?
No, your eggs cannot be fertilized when you're on your period. During menstruation there are no eggs present, there are only eggs present to fertilise during ovulation, and overulation occurs two weeks before menstruation with an egg only being present for 48 hours maximum.

Which hormone starts the menstrual cycle?
The hormone that starts the menstrual cycle is follicle-stimulating hormone (FSH), which is released by the pituitary gland. FSH stimulates the growth of follicles in the ovaries, leading to the production of estrogen and eventually triggering ovulation.
What is the purpose of the menstrual cycle in female?
The purpose of the menstrual cycle is to prepare the body for potential pregnancy. It involves the release of an egg from the ovaries, thickening of the uterine lining, and shedding of the lining if pregnancy does not occur. It is regulated by hormones like estrogen and progesterone.
Do all women ovulate two weeks after their period?
No - typically ovulation occurs two weeks BEFORE menstruation, if a womans cycle is around 28 days that means it's also two weeks after her period but if her cycle is longer than ovulation will occur later than that. Everyones menstrual cycle is different.

The average menstrual cycle is 28 days which is shorter than a month, cycles can change, and months aren't all the same lengths - there's no reason at all to think your period would always occur on the same day every month.
