Every woman in adolescence should lead ovulation calendar. Before marriage it will allow it to detect and treat menstrual disorders. After marriage ovulation calendar useful to know the day, the most suitable for conception and days of "safe sex" for the prevention of unwanted pregnancies.
What is necessary to conduct ovulation calendar
Ovulation - this release mature egg from the ovary. This point is very important because it characterizes how well the system is functioning childbearing women.
Ovulation occurs in the middle of the menstrual cycle. For example, if the menstrual cycle is 28 days, ovulation occurs on day 14-16. The menstrual cycle start counting from the first day of menstruation and the come to an end - the first day of a new menstrual period.
During the first half of the menstrual cycle (before the ovulation) under the influence of ovarian hormones estrogen and follicle-stimulating hormone (FSH), pituitary oocyte maturation occurs, then it breaks vesicle (follicular), wherein the mature and released from the ovary (this ovulation). The egg lives only a day, during which time she has to get into the fallopian tube, and meet with sperm to form an embryo.
In the second half of the menstrual cycle "work" other hormones luteinizing hormone (LH), the pituitary and ovarian hormone - progesterone

They create conditions for the fertilized egg to advance the implementation of the fallopian tube and into the uterine wall.
If pregnancy does not occur, then the mucous membrane of the uterus is rejected and the next menstruation occurs.
Ovulation Calendar is necessary to know the days of "safe sex" (a natural method of contraception), and days of highest probability of conception. But before you start keeping a calendar, you need to learn to "pick up" signs of ovulation.
Some women ovulate manifested transient pain on one side of the lower abdomen (where matured and left the egg from the ovary), discharge of mucus from the vagina and increased sexuality

. But sometimes ovulation does not manifest itself, then can come to the aid of the method of determining the basal temperature (in the rectum), which decreases the day of ovulation and rises the next day.
Ovulation can be confirmed with the help of test strips (you can buy them at the pharmacy), detects the presence of luteinizing hormone in urine. Tests carried out twice a day from 9 to 15 day menstrual cycle. A positive result indicates that ovulation occurs in about 16-28 hours. In prenatal ovulation
Ovulation - How to determine as accurately as possible?
It can be confirmed during the ultrasound.
As can be seen from the above, the highest probability of conception occurs within days after ovulation. Is it possible to become pregnant at a different time? It turns out you can. The fact that spermatozoa mostly live 1-3 days, and some bearings - to 4 days. Therefore, they may wait for the egg from the ovary, even if the sexual act was for 3-4 days before ovulation.
Knowing his days of ovulation, a woman will always be fully prepared, it can be used natural contraception method or simply do not panic if the condom broke. And if she is ready to become a mother, you can calculate in advance the time for conception.
Often ovulation calendar is required in case of violation of the menstrual cycle, for a correct diagnosis.
The Ovulation Calendar is celebrated time of ovulation and its characteristic features. Before you use a calendar for natural contraception or conception, it is necessary to conduct from 6 months to a year.
How to use ovulation calendar for natural contraception and conception
This technique is suitable only in the case of a regular menstrual cycle, with small deviations. The most likely time for conception - this time for the day after ovulation.
Time for a natural birth - this time, which begins two days after ovulation (the extra day - the correction for an error in the date of ovulation) and ends on the first day of the next menstruation. This is the so-called absolute sterility - the egg is not, and it will be a very long time.
Time relative sterility - this is the first half of the menstrual cycle, the egg at this time is not yet ripe, but the sperm have a chance to wait for her. Safer time for sex - this time, the most distant from ovulation.
Ovulation Calendar - a great method to determine the day of ovulation, and if a woman leads him on a regular basis, it allows her an honorable way out of many situations.
How to calculate ovulation
The menstrual cycle can be divided into three phases - the follicular phase, the phase of ovulation and the luteal phase, or the phase of the so-called corpus luteum. In order to calculate the menstrual cycle, it is necessary to know all three phases.
The follicular phase of the menstrual cycle - a period of time from the first day of menstruation before ovulation. During the follicular phase follicle begins to develop in the egg. Ovulation, the second phase begins at about the fourteenth day of the menstrual cycle
The days of the menstrual cycle: Four phases
. The process of ovulation stimulating hormone of the corpus luteum. Finally, the luteal phase - a period after the release of the egg from the ovary to the onset of menstruation.
The highest chances of getting pregnant in women - in the period beginning in about five days before ovulation and ending two days after ovulation. To calculate the menstrual cycle, it is necessary to recall the first day of the last menstrual period - it will be the first day of the menstrual cycle. Menstrual cycle ends on the last day before the start of the next menstrual period. For most women, the menstrual cycle takes an average of twenty-eight days, although the duration of the menstrual cycle is especially individual. Ovulation starts on the fourteenth day of the menstrual cycle - this means that women whose menstrual cycle duration is, for example, thirty days, ovulation starts somewhere on the sixteenth day.
Another way to determine the start of ovulation - a measurement of basal body temperature. Basal body temperature - it is the lowest temperature of the body at rest. Typically, the basal temperature is measured immediately after awakening - generally after the start of ovulation temperatures average half a degree centigrade higher than usual. Finally, ovulation can be determined by a change in vaginal discharge - with the beginning of ovulation discharge becomes thicker, denser, and after ovulation - more viscous.
