Pregnancy test& early test: know for sure if you are pregnant.

A positive pregnancy test is the beginning of a new, exciting phase of life. But how does such a test actually work, when does it deliver a reliable result, which test is the best and at what time of day should it be carried out?? You can find answers to these questions here.

In this guide you will find information on the following topics:

Pregnancy test – from when?

Usually, the absence of menstruation is the first sure sign of pregnancy. From the first day of the missing menstruation the pregnancy test is therefore considered reliable.

However, since many women who wish to have a child are looking forward to the test result much earlier, there is the possibility of testing positive as early as three to four days before the period stops, using so-called early tests.

A blood test at the gynecologist can also detect pregnancy as early as six to nine days after conception.

When is a pregnancy test reliable??

The classic urine pregnancy test provides a reliable result about 14 days after fertilization of the egg. So from about the first day of the expected period. Only then is the concentration of the pregnancy hormone in the urine so high that the test can provide a very reliable result.

If you want to know earlier, you can test with an early pregnancy test three to four days before your expected period. These tests are so sensitive that they detect even the smallest amounts of the pregnancy hormone in the urine. However, the early test has a significantly higher error rate. It therefore shows a negative result more often, even though you are actually pregnant.

To be on the safe side, a pregnancy test should only be carried out after the period has stopped.

When is a pregnancy test useful?

This question can only be answered very subjectively. Of course, every woman who wants to have a child wants to be sure quickly that she is pregnant. Therefore, the early tests have their justification. If the early test shows a positive result a few days before the expected menstrual period, this can be considered quite reliable, whereas a negative result can also be false. Then it is to continue to wait. And this test of patience can be quite stressful for a woman.

A negative test result is less certain than a positive result
If the test is negative, pregnancy cannot be safely ruled out. Depending on the length of the cycle and the concentration of the hormone in the urine, it is also possible that a second test a few days later will still be positive. If there is no period and other signs of pregnancy are detected, such as a pulling sensation in the breasts or nausea, it is worth repeating the test after three to four days.

When is the best time to do a pregnancy test?

Now that it is clear that testing should ideally begin on the first day of the missed period, or with an early test at the earliest four days before, the question of the appropriate time still arises. The more advanced the pregnancy, the higher the concentration of the pregnancy hormone in the urine. And this hormone can of course be measured all day long. The test in the morning urine is therefore only necessary if you want to test before the period has already stopped. You can find out why the morning urine is particularly suitable here in the guidebook.

When after implantation?

The implantation of the fertilized egg occurs approximately between the sixth and tenth day after actual fertilization. Four to ten days later, i.e. between the 14th day of pregnancy. and 16. day after fertilization, a pregnancy test is considered reliable. Since most women do not feel the implantation of the egg, it is not possible to say exactly when it has actually taken place. As a rule of thumb, therefore, it is advisable to test about two weeks after ovulation.

How the test works and how to use it

The pregnancy test measures the concentration of the pregnancy hormone in the urine. Depending on the sensitivity of the test, the result can already be read a few days before the period stops. Morning urine is best for early testing.

What is measured?

The pregnancy test measures the concentration of the pregnancy hormone HCG in the urine. HCG (human chorionic gonadotropin) is a hormone that is produced right at the beginning of pregnancy and reaches its maximum concentration between the tenth and 12th week of pregnancy. Week of pregnancy reached. HCG is crucial for maintaining pregnancy, it stimulates the corpus luteum to produce progesterone, which prevents further ovulation during pregnancy. From about the fourth month of pregnancy, the mature placenta produces progesterone itself. At this point, the HCG concentration drops again significantly.

When should the test be carried out – better in the morning or in the evening??

Although the HCG concentration in the urine can of course be measured throughout the day during pregnancy, it is always recommended to test with the morning urine. The more advanced the pregnancy, the higher the HCG value.

If you test after your period has stopped, this can be done regardless of the time of day, as the HCG concentration is probably already sufficiently high. An early test, on the other hand, provides a more reliable result with the morning urine.

Why pregnancy test with morning urine?

The morning urine, which has been collected in the urinary bladder throughout the night, contains the highest HCG concentration. Therefore, testing in the morning is considered the most reliable, especially if you want to test a few days before your period stops.

What do the lines on the pregnancy test mean??

A common pregnancy test has two small viewing windows. After holding the test in the urine for a few seconds, a stripe should become visible in the first viewing window after just a few seconds. This strip is just the control strip and is marked with the letter "C". It indicates whether the test is working and whether sufficient urine has been collected.

If this control strip does not appear, this indicates that the test has not worked. This can be due to the fact that the control substance in the test is superimposed, for example. Pregnancy tests also have expiration dates.

After a wait of two to five minutes you can also read the result. If the test is positive, that is, if there is a pregnancy, also appears in the second viewing window, called the test area and marked with a "T", a dash. Depending on the HCG concentration, this can be lighter or darker, but in any case clearly visible. If, on the other hand, no second line appears, there is either no pregnancy or the HCG concentration is not yet high enough. If there are still signs of pregnancy, a second test is worthwhile after three to four days.

Are color deviations decisive?

Whether the second line on the pregnancy test is light or dark does not affect the result. If the second line appears, there is a 99% chance that you are pregnant. If the test is performed in the evening or even a few days before the period stops, the second line may be slightly less pronounced, but still visible. It’s simply because of the lower HCG concentration in the urine.
