Ovulation pregnancy planning calendar and calculator
Planning a long-awaited pregnancy is sometimes a rather difficult task. To determine the most favorable date of conception, quite a few different methods are used. This article will talk about one of the methods for determining the best days for fertilization - the pregnancy planning calendar for ovulation.
What it is?
Such a calendar will help future parents to plan a potentially better date for conceiving a baby. This is the date of ovulation - according to doctors, this is the best time for conception to occur.
In order to understand how to properly use such a calendar, you must first understand what is ovulation. This concept means the moment when a woman's egg cell is ripe and ready for fertilization. With a normal menstrual cycle, ovulation occurs every month.
Some women also have anovulatory menstrual cycles. They arise in case there is any pathology. In such a situation, ovulation occurs irregularly. This can lead to some difficulties in conceiving a child.
With a regular menstrual cycle, the day of ovulation usually falls on its middle. On this day, the probability of conceiving a baby is the highest. However, not only in one day fertilization can occur - the probability of pregnancy is quite high a couple of days before and a couple of days after the day of ovulation. This special favorable period must be marked in the planning calendar of the desired child.
Currently, there are automatic calculators to determine the date of ovulation. To determine the most favorable period for conceiving a child, the date of the last ovulation is entered into a special field of the calculator. Then he automatically calculates both the actual date of ovulation and the possible “green corridor” for planning conception.
Calculation method
To determine the date of ovulation, you can use a variety of techniques. They allow you to calculate the required day fairly accurately. Each method has its advantages and disadvantages.
Mathematical method
When drawing up a pregnancy planning calendar for ovulation, the dates of the first day of the month are always marked. This date is very important, since it is precisely for her that the estimated day of ovulation is calculated.
For example, with a 28-day menstrual cycle, the estimated date of ovulation falls on day 14. In this case, the days of the cycle from 12 to 16 can be considered a favorable time for the intended conception. At this time, the probability of successful fertilization is rather high.
Not always the menstrual cycle works "on the clock." For some women, it is a different number of days - so, in one month the duration of the menstrual cycle can be 28 days, in the other - only 25. In this case, it will not work to accurately calculate the date of ovulation through a simple mathematical calculation. The risk of obtaining an unreliable result in this case is quite high.
Determination of basal temperature
For a more accurate determination of ovulation, doctors recommend using the measurement of basal temperature. It is measured in the morning hours, as a rule, when a woman is in bed.
Noted that ovulation increases basal temperature. It usually increases by 0.2-0.3 degrees Celsius. This increase in basal temperature contributes to a number of female sex hormones that appear in the blood at this time.
We use ready-made tests
Tests for determining ovulation today can be found in every pharmacy or large supermarket. They differ in cost, the country of origin, have different packaging designs, as well as certain small nuances during the process.
The essence of such a home "survey" is very simple. The test determines the level of luteinizing hormone in the urine - it is responsible in the female body for the onset of conception. The level of hormone in different phases of the menstrual cycle varies. Immediately before ovulation, its concentration in the body increases significantly, which determines this test.
For the test will require urine. A small amount of contact time with urine is enough to get a result. After a few minutes, the test will show whether ovulation has occurred or not.
During the test it is very important to follow the instructions. In it, the manufacturer necessarily makes a note about what time of day it is best to conduct such an examination, how long the urine test should be held, and also indicates other, equally important nuances.
Often women have a question about whether errors are possible during the test. The probability of this does exist, and although the accuracy of the measurement is quite high, there are a number of different reasons that influence the obtaining of a reliable result.
We use modern techniques
Perhaps the rarest, but still possible, method of determining the exact date of ovulation is ultrasound. It allows you to determine at what stage is the egg, and therefore calculate the onset of ovulation. Such an instrumental test is fairly accurate, especially if carried out on modern ultrasonic devices.
Forecast of the sex of the unborn child
Some couples dream of having a beautiful daughter, while others dream of the appearance of a long-awaited heir. The question of planning the sex of the child today is highly relevant. Ever since antiquity, people have tried, using a variety of folk methods and tricks, to influence the sex of a child before its conception.
Currently, scientists have a lot of data on how the formation of the male or female body. Chromosomes that are found in germ cells influence sex determination. In order for a boy to be born, it is necessary that the Y chromosome be necessarily present in his genetic apparatus. To inherit her baby can only from dad.
In the female body there are no Y chromosomes, but there are only paired X chromosomes. Two X-chromosomes cause the birth of a little girl.
Scientists have found that each type of sex chromosome has a number of features. So, Y-chromosomes are more mobile, fast. After ovulation, they quickly reach the fallopian tube, but if fertilization for some reason did not happen, then they also quickly die.
X-chromosomes have several other properties. They are considered slower, but more viable. In the fallopian tube, they may persist somewhat longer.
Thus, the way of planning the sex of the child is already outlined. Immediately, we note that it is not an absolute guarantee of conceiving only a boy or only a girl. In each of the methods there may be errors.
So in order to increase the likelihood of a future heir to the world, you should plan sexual intercourse on the day of ovulation, or a maximum of 12-15 hours before it. In this case, the mobile Y-chrosomes will not have time to die.
Of course, in vitro fertilization (IVF) is the most accurate method for planning the sex of a child. In this case, the fertility specialist will be able to determine the sex of the unborn child as accurately as possible, since he knows the genetic set.
