I think I know what your saying.
Because a long time ago (well not that long ago) girls used to have babies when they were very young because tehy didnt have very long life spans like we do now, they usually only lived to be about 20 or 30 years old. So they would have children in their teens. Thats why we today get our periods when were teens, tahts just the way our bodies were made.Health Question & Answer

Every month, one egg from your ovaries is released into the fallopian tubes to fertilized by sperm. If the woman doesn't have sex, The egg dies and the uterus then cleans itself for the next time. The lining of the uterus is torn away and that is when the period starts.Health Question & Answer
Starting at ovulation, the uterus starts preparing for fertilised egg, by thickening so the egg has a soft place to burrow into. After a couple of weeks it realises there is no egg so it gets rid of the extra stuff (bleeding and goop) .Health Question & Answer

The menstrual cycle is a recurring cycle of physiologic changes that occurs in reproductive-age females. Overt menstruation (where there is blood flow from the vagina) occurs primarily in humans and close evolutionary relatives such as chimpanzees.[1] The females of other species of placental mammal have estrous cycles, in which the endometrium is completely reabsorbed by the animal (covert menstruation) at the end of its reproductive cycle. This article focuses on the human menstrual cycle.
The menstrual cycle is under the control of the hormone system and is necessary for reproduction. It may be divided into several phases: menstruation, the follicular phase, and the luteal phase.[2] Ovulation defines the transition from the follicular phase to the luteal phase. Counted from the first day of menstrual flow, the length of each phase varies from woman to woman and cycle to cycle. The average cycles length is 28 days.[2] Hormonal contraception interferes with these normal hormonal changes with the aim of preventing reproduction.
Stimulated by gradually increasing amounts of estrogen in the follicular phase, the lining 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). The dominant follicle releases an ovum, or egg, in an event called ovulation. After ovulation, 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 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 or mood changes, for example). A woman's first menstruation is termed menarche, and occurs typically somewhere around age 12. The end of the reproductive phase of a woman is called the menopause, which occurs somewhere between the ages of 45 and 55. Medical problems such as anemia and infertility can be due to disorders of the menstrual cycle.
[edit] Terminology
The menarche is one of the later stages of puberty in girls. The average age of menarche in humans is 12 years, but is normal anywhere between ages 8 and 16. Factors such as heredity, diet and overall health can accelerate or delay menarche.[3] The cessation of menstrual cycles at the end of a woman's reproductive life is termed menopause. The average age of menopause in women is 51 years, with anywhere between 40 and 58 being common. Menopause before age 35 is considered premature. The age of menopause is largely a result of genetics; however, illnesses, certain surgeries, or medical treatments may cause menopause to occur earlier.[4]
The length of a woman's menstrual cycle will typically vary, with some shorter cycles and some longer cycles. A woman who experiences variations of less than eight days between her longest cycles and shortest cycles is considered to have regular menstrual cycles. It is unusual for a woman to experience cycle length variations of less than four days. Length variation between eight and 20 days is considered moderately irregular. Variation of 21 days or more between a woman's shortest and longest cycle lengths is considered very irregular (see cycle abnormalities).[5]
[edit] Phases
The menstrual cycle is divided into several phases. The average length of each phase is shown below:
Name of phase Average start day
assuming a 28-day cycle Average end day
menstrual phase 1 4
follicular phase (also known as proliferative phase) 5 13
ovulation (not a phase, but an event dividing phases) 14 14
luteal phase (also known as secretory phase) 15 26
ischemic phase (some sources group this with secretory phase) 27 28
[edit] Menstruation
Main article: Menstruation
Menstruation is also called menstrual bleeding, menses, a period or catamenia. The flow of menses normally serves as a sign that a woman has not become pregnant. (However, this cannot be taken as certainty, as a number of factors can cause bleeding during pregnancy; some factors are specific to early pregnancy, and some can cause heavy flow.)[6][7][8] During the reproductive years, failure to menstruate may provide the first indication to a woman that she may have become pregnant.
Eumenorrhea denotes normal, regular menstruation that lasts for a few days (usually 3 to 5 days, but anywhere from 2 to 7 days is considered normal).[9] The menstrual fluid is largely a mixture of blood and tissue from the uterine lining (endometrium).[Health Question & Answer
