It is impossible to accurately determine the day of release of the egg from the follicle, since the process can be affected by a variety of factors, for example, medications, diet, illness, hormonal imbalance , irregular menstrual cycle, etc. It should be noted that such calculations are never used as a method of contraception.

This method can only be used by women with a regular menstrual cycle that lasts 28 days. With such layouts, an egg ready for fertilization leaves 14 days before the onset of menstruation.

To determine the exact date, add 28 (cycle duration) to the first day of the last menstruation. From the date received, it is counted 2 weeks ago.

Under the influence of various factors mentioned above, the maturation of the egg can occur a few days earlier or later, while the spermatozoa live for 3 days, so it is recommended to plan conception for 5 days before the estimated date of ovulation.

How to calculate the ovulation graph by basal temperature

Basal temperature (abbreviated BT) is observed during sleep, so it is measured immediately after waking up. With the help of measurements, it is possible to determine the time favorable for conception, since during the period of ovulation, the thermometer readings rise.

BT fluctuates at different periods of the cycle, for example, in the first phase, under the influence of estrogen, it is low. These conditions are ideal for the maturation of the egg and its release. Average standard indicators at this time are from 36.3 ° to 36.5 °.

An increase or decrease by 0.1 ° C is allowed. During ovulation, it rises significantly to 37.3 °. This temperature will last until the onset of menstruation. If menstruation has not begun, high BT indicators are kept for 18 days, then one can suspect a successfulconception.

To make a more accurate graph, you need to correctly measure:

  • Every day at the same time immediately after sleep getting out of bed;
  • With the same thermometer. It must be kept near the bed so as not to get up. You should also not make sudden movements;
  • After inserting the thermometer, they lie quietly for 5 minutes, then the indicators are entered into the calendar.

For the indicators to be accurate, the time of night sleep should be long - not less than 6 hours. A lot of factors can affect the indicators, for example, the same medicines, alcoholic beverages, evening intercourse, illness, etc. These factors also need to be written down in a notebook.

A correctly drawn up schedule will show the date of ovulation or its absence ... When planning a pregnancy, it is advisable to take such measurements over several cycles in order to determine the date of egg release as accurately as possible.

Ultrasound allows you to calculate ovulation as accurately as possible. In addition, this method is perfect for women with irregular menstrual periods. Such an event allows you to track the development and maturation of the follicle and the moment of its rupture.

For women with a regular cycle, ultrasound is started 3-4 days before the expected date. Those whose cycle malfunctions begin to be observed earlier - 5 days after the end of menstruation, the procedure is carried out every 2-3 days.

Special tests are now available at any pharmacy. With their help, the presence of luteinizing hormone in the urine is determined, a significant release of which occurs a day and a half before the rupture of the follicle.

Women with an established menstrual cycle should begin such a kind of testing 17 days before the onset of menstruation. However, for those who do not have a cycle set, this will be problematic, since it is impossible to determine a suitable time for testing. So ultrasound monitoring is recommended for the latter.

There are women who can independently calculate the day of ovulation without using any means. To find out the exact date, they only need to listen well to their body.

During ovulation, aching pains of varying intensity may occur, the chest swells, the psycho-emotional mood changes, sexual desire increases and, of course, the nature of vaginal discharge changes , they tend to become more viscous and abundant.

calculate the sex of the planned baby by ovulation

Scientists have found that Y-sperm (carrying the male chromosome ) are more mobile for the X-sperm responsible for the birth of a girl. The former are more likely to be the first to reach the egg. However, they are very sensitive to the acidic environment of the vagina and quickly deteriorate, falling into such. But the X chromosomes are slow, but more tenacious, they can hold out in the fallopian tube for several days in anticipationovulation.

Closer to a favorable day for conception, an alkaline environment begins to prevail in the vagina, therefore, accordingly, more favorable conditions for the life of Y-spermatozoa are created. Knowing the date of follicle rupture, you can significantly increase the chances of germ cells, thereby choosing the gender of the future baby.

How to calculate ovulation for conceiving a boy or girl? Quite simply - on the day the egg is released, there is a great chance to conceive a boy. To conceive a girl, it is recommended to start attempts starting 6 days before ovulation and end 4 days after it.
