Manual test ovulation: positive pregnancy test
All the girls know that conception occurs in the ovulation period. It was at this time the oocyte reaches its maximum maturity and is ready for fusion with the sperm. In order to accurately calculate the most fertile day, and there is a test for ovulation.
The principle of operation of the test
As the egg Matures in a woman’s body there are strong hormonal changes, in particular, there are significant emissions of the hormone estrogen. Once the estrogen level reaches a value, which is necessary for the onset of ovulation in a woman’s body there is another phase – the release of luteinizing hormone. Then within a day or two of ovulation is observed. In this period the ovum is ready for fertilization. Ovulation test can detect luteinizing hormone in the urine of women, thereby to give a signal on the occurrence or absence of the process.
Today, there are several different types of tests, working on the same principle, namely:
- Test strips
The principle of operation is similar to a pregnancy test. A paper strip is lowered into the urine for 5 – 10 seconds, after a few minutes the evaluation results. If a positive result will appear the second strip. The disadvantage can be attributed to the unreliability and inaccuracy.
- Tests in the form of cassettes or tablet test
Produced in the form of a plastic housing with digital window. On the tape dripping urine, and after a certain time there appears the result in the form of one or two strips. The disadvantage is their high cost.
- Jet tests
Considered the best and most reliable way of determining ovulation. They should put it under urine stream for a few seconds, and then wait for the result.
- Electronic or digital tests
Determine the content of luteinizing hormone in the saliva. It is the most accurate and reliable method which eliminates the option of the error. The saliva before ovulation changes its properties. When considering a device, you may notice specific lines and patterns, talking about the approaching release of the egg.
- Tests reusable
Produced in the form of the device with a set of test strips. After dipping the strips in urine, they are inserted into the device and monitor the result.
In what period should I do the test?
An important parameter, which determines the best day to commit a test for ovulation, is the length of the menstrual cycle of a girl. When regular, normal physiological cycle is 28 days ovulation is around mid-cycle, i.e. on the 14th day. But testing it is better to start with the 11 day cycle. The easiest way the number of days to subtract 17, the resulting number will be the day when is the best time to start using the test. In addition, frequent and longer cycles, or, on the contrary, short. The table below shows the days when they work best.
|Cycle length||The day of ovulation|
Rules for the use of test
There are a few rules that should be followed:
- testing is best done in the morning;
- do not drink large amounts of fluid for several hours before testing;
- for 3 to 4 hours before the test to avoid ovulation urination;
- do not conduct the test on the first portion of morning urine in avoiding erroneous results.
You must first drop test in a container of urine for 10 – 20 seconds and then after 4 – 5 minutes to check it out. To obtain the most accurate results is best done at the same time of day for several days. To evaluate the final result, it is necessary to correlate the line (left) and line of control (right). The ovulation test is making a statement, which said: the brighter the line, the closer the period of the release of luteinizing hormone.
A negative test
If ovulation does not occur, the test indicates a negative result. But that’s not the only reason for the lack of a second strip. The reason for the negative test may also be:
- lapsed or the unsuitability of the test.
- the completion of ovulation.
So to avoid errors you should always possible to calculate the favorable days for conception, and use only the best and proven tests.
It is important to understand that the tests show only a rise or fall in the level of luteinizing hormone. That is why there are times when such an increase is not a guarantee of ovulation.
Increasing the concentration of luteinizing hormone may occur in these cases:
- in disorders in the hormonal system;
- the syndrome of exhaustion of ovaries;
- during postmenopause;
- in case of insufficiency of the excretory system, particularly the kidneys.
In addition, the rise in the level of luteinizing hormone and, as a consequence, a positive test result can influence other hormones. Because of the structural similarity between HCG and luteinizing hormone test may be false positive, although no ovulation, and the girl got pregnant. The same applies to follicle stimulating and thyroid stimulating hormones.
To stimulate ovulation sometimes apply the HCG injection. In this case, there may also be a false positive test result.
When can I conceive a child?
For that became clear when exactly you should proceed to conceive a child, it is important to remember two rules:
- When approaching ovulation test becomes positive. This means that in the coming hours the ripened egg is released into fallopian tube and waits for fertilization.
- After leaving the ovary the egg can live about a day. If fertilization does not occur, the egg dies.
Based on this, do not immediately after the detection of a positive test result to resort to the conception of a child. It is best to wait about 5 – 7 hours to the egg certainly came to the fallopian tube. But wait too long, more than 12 hours is not worth it, otherwise the egg will die.
The sex of the baby
Today, there are many different ways to conceive the desired gender of the child. But the most reasonable and real the method is based on ovulation.
Many people know what the X and Y chromosomes. This is what determines the sex of the baby. If the sperm carries a Y chromosome, it will develop a male embryo, and if X chromosome, female. An important feature is that the sperm «boys» are living quite a bit less than two days, but move faster. And the sperm with the X chromosome is less mobile, but able to exist about 4 to 5 days. That is, the closer intercourse is to the period, the more likely that it’s a boy.
Principles of conception of a male embryo:
- Men should avoid hypothermia and overheating, otherwise it will lead to a reduction in the number of sperm carrying Y chromosome.
- Sexual intercourse is recommended on the day of ovulation, before that stand 4 to 5 days without sex.
Principles of conception of a female embryo:
- In order to survive the sperm with the X chromosome it is best to plan conception for 2 – 3 days when the test was positive.
- Stop sexual acts during ovulation and after it still within a few days.
