Every woman should know what ovulation is and what processes occur in her body. After all, the calculation of the date of such a period can contribute to the planning of pregnancy, as well as to avoid conception. To calculate ovulation, you can use various methods.
The onset and duration of ovulation
Ovulation in medicine is a natural process in the female body, which is characterized by the release of mature eggs from the follicles. It is at this point that fertilization can occur, because the egg is ready for conception.
This condition in women of reproductive age occurs every month. Maturation of the follicle begins, it then instantly breaks and releases the entire egg, which is sent to the uterus and is waiting for fertilization.
The ovulatory phase lasts from the seventh day of the cycle to its middle. In each case, this phenomenon occurs individually. However, the duration of ovulation is the same - from twelve hours to two days. Conception is possible during this period.
Ovulation usually occurs from fourteen to sixteen days before the expected date of the first day of menstruation. Most often it concerns a cycle that lasts exactly 28 days. However, with more or fewer days of the cycle, the ovulatory period may be from the eighth to the eighteenth day.
If the cell is fertilized, it enters the uterine cavity and is attached to the wall. So begins the pregnancy. In the absence of conception, the released egg perishes.
Calculating the day of ovulation as a method of contraception
It is important for women to know how to correctly calculate the date of ovulation. This is necessary for those planning a child.
Calculating the days of the ovulatory period can also help avoid unplanned pregnancies.
To determine such a day, various methods are used:
- Calendar method.
- Graph of basal temperature.
- Test to determine ovulation.
- Ultrasound procedure.
In addition, a woman can determine ovulation according to her state of health.
In addition, cycle changes are possible after childbirth, abortion, and before menopause.
Calendar method for determining the ovulatory period
First, we learn how to calculate the days of ovulation by monthly, so as not to get pregnant. This method is also called calendar. To establish the time of ovulation using this method, you need to take a regular calculator.
It is important to remember that this method is justified only in the situation when there is a regular cycle in a woman. Normally, if it lasts 28 days. The egg cell comes out two weeks before the onset of menstruation.
So, how to calculate the day of ovulation in a calendar way? To calculate this date, it is necessary to add twenty-eight days to the first day of the month. Then it should be deducted exactly fourteen days.
This day in the calendar, calculated by such arithmetic operations, will be the date of ovulation.
When using the calendar method, you need to know that the ovulatory period may occur several days earlier or later. This is explained by the fact that this process is influenced by such factors as diseases, stressful situations.
You can calculate the date of the onset of the ovulatory period online at certain sites. This method is based on the calendar method of diagnosis.
How to calculate the day of ovulation by measuring the basal temperature
You can determine ovulation by measuring the temperature, but not normal, but basal. To carry out this method, you need to prepare a thermometer, notebook and pen.
To obtain a reliable result, you must observe the following measurement rules:
- the procedure should be done at the same time;
- one should not get out of bed to measure and even not be allowed to make sharp movements;
- insert the thermometer into the anus;
- in a state of calm measure the temperature of about five minutes;
- in a notebook they build a graph and write down the results in it every day.
It is necessary to know that the indicators can be affected by the sexual act on the eve, various diseases, primarily the urogenital system, the use of alcoholic beverages. Therefore, you should not drink alcohol and have sex the day before the measurement. You also need to pay attention to the state of health.
The results can be interpreted as follows:
- 36.9 degrees - observed the day before ovulation;
- from 37 to 37.4 degrees - the day of ovulation;
- from 36.5 to 36.8 degrees - the mark will be in the initial days of the monthly cycle.
This method is accurate and reliable as many factors are possible.
Other counting methods
Other ways to determine the date of ovulation include:
- using test strips;
- condition of the female body;
- Pelvic ultrasound - folliculometry;
- examination of cervical mucus.
The test can be purchased at any pharmacy. It is similar to those that define pregnancy, but it is called a test for diagnosing ovulation. The difference between these tests are indicators of urine.
In the first case, it contains chorionic gonadotropin. The test for determining ovulation is based on the determination of luteinizing hormone, which appears in the urine one to two days before the onset of the ovulatory period.
This is due to the fact that follicle rupture is possible due to this substance, the increase of which is observed immediately before ovulation.
Instructions for performing the procedure are as follows:
- Take the test out of the packaging.
- Collect urine in a clean container in the early morning.
- Place the indicator to the specified boundary in the biological material.
- Strip out after a certain time and decipher the result.
- Two strips indicate the beginning of the ovulatory period, one - the absence of ovulation.
The test is preferably carried out seventeen days before the next menstruation.
Ovulation can be determined by the following features:
- pulling pain in the lower abdomen to the right or left;
- increased mucus secretion from the vagina;
- discharge in this case, viscous, transparent;
- increased sexual desire;
- general weakness.
Folliculometry and the study of biological material from the cervical canal are considered more accurate methods.
How to calculate ovulation for conceiving a girl and a boy
Studies have been conducted that prove that not only fertilization depends on the day of ovulation, but also the sex of the child.
This method is called Shettles method.
The table is simple:
| Monthly cycle day | Child sex |
|---|---|
| Sex on the day of ovulation, a day or two before her | Probability of having a boy |
| Unprotected sex three to five days before ovulation | The probability of conceiving a girl |
However, it is important to remember that this method alone cannot guarantee the conception of the desired sex. In this case, it is important to observe other methods that increase the likelihood of a forecast.
Increased probability of gender prediction
Conception girl determine sperm X, which a smaller number in the semen. They are characterized by inactivity, but survivability. Therefore, in order to increase the probability of pregnancy by the girl, a change in the vaginal microflora (acidic is necessary) and a decrease in the amount of sperm are recommended.
Sperm Y is very fast, they live less, there are a lot of them in sperm. Therefore, to conceive a boy should accumulate sperm, therefore, before ovulation, sexual intercourse should be avoided for three to four days. Necessary alkaline environment during sexual contact.
To increase the chances of conceiving a girl or a boy, it is recommended to follow other methods:
- special food to increase the likelihood of conception by the desired sex;
- using the conception table for the months of birth of a man and a woman;
- the use of the ancient Chinese table for determining sex (after the woman’s age and the month of fertilization);
- conception by blood type;
- recommended posture for conceiving a girl or boy.
To enhance the forecast of the birth of a child of the desired sex, it is best to use more than one method.
