It’s a good idea to use a calendar to keep track of periods. It marks the first day with an “X”. Will continue counting the number of days until you have the following bleeding. If this is done every month, you can determine how many days elapse between each period and thus know when to start the next cycle. If records are kept on the calendar and periods are regular, can be determined every month when the next menstrual cycle starts. If the periods are not regular, you may still notice some signs in advance of the bleeding.

The sensation of pain in lower back pain and menstrual cramps vary from woman to woman can be mild or severe bouts or by continuous and sometimes sit in the back and thighs. In most cases, with advancing age aches usually less intense. For women who have severe pain or even disabling, it is recommended to go with your doctor so that they can indicate a treatment. Other measures that may help reduce pain are warm baths or applying heat in the lower abdomen. Exercise also appears to reduce these pains.

Some women feel depressed or easily irritated during the days before the period. Others get angry or cry more quickly than usual. Others may have “craving” to eat certain foods. These mood swings are usually due to PMS. Premenstrual syndrome is associated with hormonal changes and may affect the way women feel both emotionally and physically.

Some women feel that swell and this is due to fluid retention, others notice their breasts swell, are tender and may even hurt. Others have a headache. These symptoms usually disappear after the beginning of the period, but is likely to come back month after month. Exercise helps these women to feel better. It also recommends limiting caffeine intake.

It is common for women between 39 and 51 years begin to make less frequent periods.

Menopause occurs, on average, around 50 years old. Menopause is the last period in the life of a woman means a woman is no longer ovulating (producing eggs) and therefore can no longer become pregnant. Like menstruation, menopause varies from woman to woman, and may take several years to happen. Some women have early menopause because of surgery or other treatment, illness or other causes.

The menstrual cycle involves a series of changes that passes through the body of the woman. These changes are governed by the female hormones estrogen and progesterone produced in the ovaries by the body. The menstrual cycle is repeated over many years, from puberty to menopause, except when interrupted if pregnancy occurs.

In the menstrual cycle can identify two phases: the follicular and luteal, both divided by the phenomenon of ovulation.

The follicular phase begins on the first day of menstruation and ends at the time of ovulation. During this phase the pituitary gland begins to secrete a hormone that travels through the bloodstream to act on the ovaries, which favors the development and maturation of a follicle. This is called an ovarian follicle because the follicle develops, where the future egg.

The follicle grows and matures when ruptures and releases an egg. During this phase, changes occur inside the uterus to prepare it for nest egg if it is fertilized with sperm. The cervix secretes or produces large amounts of mucus to facilitate their arrival from the vagina to the fallopian tubes where it will meet the egg.

Ovulation is the release of eggs from the ovary. This takes at most 36 hours, during which it can be fertilized, otherwise, it disintegrates and is resorbed.

Ovulation begins the luteal phase in which the “scar” left on the ovary of the area where the egg is released into what is called the corpus luteum. The corpus luteum produces large amounts of progesterone that promotes the accumulation of nutrients for the fertilized egg has to nourish if fertilization is presented.

Progesterone also causes the mucus secreted by the cervix becomes thick, which prevents the entry of sperm into the uterus. The egg is picked up by the fimbriae of the fallopian tubes. If the egg is fertilized (now called egg), adheres or nest in the endometrium, the brain sends signals to continue producing the hormones necessary for pregnancy to take its course. If fertilization does not occur, the corpus luteum dies and to stop producing hormones, these levels drop sharply and approximately 10 days later, the tissues that accumulate inside the uterus is shed.

It is considered a menstrual cycle since the first day of bleeding (day 1) until the first day of bleeding of the next cycle. While the average is 28 days per cycle, is considered normal 21-day short course and long cycles of up to 35 days.

It can support special tests to determine levels of sex hormones or imaging to observe the uterus and adjacent structures and to identify why the rule is not falling.

Treatment
Will depend on the type of amenorrhea. The primary use for hormone replacement (estrogen and progesterone).
In high school, if pregnancy is carried obstetric care. If it is due to menopause or hormonal disorders be administered supplements. For other cases will seek to remove the cause. p. eg. tumors.
