. And, like other changes associated with puberty onset of menstruation may be due to some problems: some girls are looking forward to the beginning of the month, the other is this aspect of the process of growing up seem scary or unpleasant. Moreover - many girls do not even imagine what actually happens during the menstrual cycle and what the female reproductive system.
With the onset of puberty (usually between the ages of eight to thirteen years) and begin changing physiological and psychological. Hormonal changes stimulate the rapid development of the body - including the rapid growth of breast augmentation. After the two - two and a half years after the beginning of the growth of breasts usually begin menstruation.
After about six months of the start of the first menstrual cycle, you will notice an increase in the amount of vaginal discharge. This is - a common phenomenon, about which absolutely no need to worry (you need to pay attention if vaginal secretions cause itching, have a strong odor or change color).
Starting menstruation also called menarche. The first menstrual period begins only when all the elements of the reproductive system of the body, and finally evolved perform the functions together.
Female reproductive system
The female reproductive system includes the ovaries, fallopian tubes, uterus. Ovaries oval located on both sides of the uterus in the lower abdomen - in the pelvic area. The ovaries are formed egg. Near the ovaries are long and thin fallopian tubes - they are, in fact, connect the ovaries to the uterus, a pear-shaped organ located in the center of the pelvis. The muscles of the female uterus is strong enough and able to contract and expand, making the uterus can accommodate a developing fetus, and then, during labor, to push him out.
With the onset of puberty, the pituitary gland produces hormones that stimulate the production of estrogen in the ovaries

and progesterone. These hormones have a multifaceted impact on a woman's body: in particular, they are responsible for the maturation, growth, emotions

Once a month the mature egg leaves one of the ovaries - a process called ovulation

- And into the fallopian tube, gradually moving to the uterus. A few days before ovulation hormone estrogen stimulates thickening of the endometrium, causing its walls become more dense and soft. This process - the preparation of the uterus for a possible pregnancy. If the egg is fertilized by sperm, it is attached to the uterine wall, gradually developing. If conception has not occurred - as it happens in most menstrual cycles - egg does not attach to the uterine wall, flaking and slimy with blood and unfertilized egg comes out through the vagina. This process is called menstruation.
The menstrual cycle is repeated every month for several decades, a woman's life (except, of course, the gestation period) to menopause.
Frequency of menstruation
As puberty begins all at different times, the same applies to menstruation. Some girls first menstruation begins at the age of ten, in others delayed until the fourteen or fifteen years.
The time interval between periods called menstrual cycle (the number of days from the beginning of menstruation to the next). In some cases, the length of the menstrual cycle is of standard twenty-eight days, however, the menstrual cycle may be either shorter (twenty four days) or longer (up to thirty days). Typically, early puberty, menstrual cycle duration varies and can range from twenty-one to forty-five days. And after two or three years, the cycle is normalized to an average of twenty-one - thirty-four days.
Irregular menstruation - quite common for girls who have started menstruation recently. The body takes time to adapt to rapid changes so often at this time, you can observe a violation of the periodicity of menstruation. Typically, in a year or two menstrual cycle becomes more regular, but in violation of the periodicity of menstruation often face and adult women.
