Today it is possible to know if you are pregnant sooner and sooner. The current pregnancy test is simple, comfortable and fast. It can be done at any time, although it is better in the morning, and anywhere, at home for example. Pregnancy tests are highly reliable, especially in the case of a positive result. They detect the presence of the hCG hormone in the woman's urine and show the result in just 3 minutes.

Pregnancy tests, which are sold in the pharmacy, detect the presence of the hormone hCG in the woman's urine. Chorionic gonadotropin, hCG or bêta-hCG, is the hormone secreted by the trophoblast, the cell layer present just at the beginning of embryonic development and that will give rise to the placenta, at the time the embryo is installed in the uterine wall.

The amount of hCG present in your body doubles every 2 or 3 days, until it reaches a maximum level around the 7th or 12th week of pregnancy, and then begins to decrease. This is the reason why, from week 12 of gestation, nausea and discomfort that accompanies gestation during the first trimester cease. The level of these hormones stabilizes throughout the pregnancy and is maintained for about three weeks after delivery. The test, which comes in stick or rod form, contains antibodies that react in the presence of the pregnancy hormone and detect if you are pregnant.

For the results of the pregnancy test to be reliable, it is essential to choose well the day on which we do the test, since the pregnancy hormone is detected in the urine fifteen days after conception and not before. Even if the egg has been fertilized, it is necessary to wait about 7 days for this fertilized egg to cross the fallopian tube and reach the uterus. Once there, the embryo implants itself in the uterine mucosa, that is, it nests, and for the pregnancy to continue, the secretion of the pregnancy hormone (hCG) is essential. However, until the level of the hCG hormone is high enough in the urine to be detected in the test, it is necessary to wait another week. For this reason, If you take the test before the date, that is, before having a delay of at least one day, it is likely that the test will give us an unreliable or negative result. This is the reason why you have to wait about 15 days to take the pregnancy test after fertilization.

And you not only have to take into account the day, but also the moment. Although most tests can be done at any time of the day, it is always preferable to do it in the morning, after waking up, since the urine is more concentrated. The test is more likely to be positive in the case of a recent pregnancy. The first urine in the morning is the most concentrated and, therefore, the most suitable for taking as a sample for the pregnancy test. Therefore, avoid drinking a lot of water before taking the test, since a drinking plenty of fluids can dilute the concentration of the hCG hormone in your urine and offer a false positive.

!! Congratulations!! If the result has been positive, do not hesitate, you are pregnant! The test is infallible if the result is positive, except if there has been an ectopic pregnancy, which is the one that occurs outside the uterus, or an anembryonic pregnancy (without an embryo), which although the levels of the hormone are elevated, pregnancy does not it is real. On the other hand, if the result is negative, it is possible that you are pregnant and the test did not detect it. For this reason, it is advisable to repeat the test after five or six days. In case of having suffered an abortion, you should bear in mind that the level of hormones remains high during the weeks following the abortion. Reading the test is therefore difficult after this period. The "pregnant" result could be due to a new pregnancy or a residual hCG rate from your previous pregnancy.

Since there are several different brands on the market, it is always advisable to read the instructions so as not to make handling errors. However, most of the tests follow the same principle. Simply insert the test, which is the rod or stick, in a bottle of urine that you have just collected or place it under a stream of urine and read the response after about 3 minutes. This duration varies depending on the brands, as does the coloring. You will see that a change in color indicates the presence of a certain level of hCG, while a control window allows you to check that the test has been performed correctly. In case of a manipulation error, this box can remain empty.

Pregnancy tests can be bought without a prescription at any pharmacy. The most sophisticated ones even offer a rough idea of ​​the time of pregnancy. If the result is positive and the test says that you are pregnant, it is best to go to your gynecologist, who will check your state of good hope through a blood test (blood test), carried out in a laboratory that, although they work on the same principle, will corroborate your pregnancy. In general, the results of this analysis are available after 24 hours.
