Before the absence of the rule, and perhaps before the first symptoms, the woman wonders if a pregnancy is possible. The easiest, most comfortable and fastest method of knowing if we are pregnant is the pregnancy test that you can buy at the pharmacy.
But it is important to do the test well so as not to doubt the result and avoid the typical question, will I have done it correctly?, Which can cause anxiety and nervousness. If the test is well done, the result is reliable.
When to do the pregnancy test
It is essential to choose well the day we do the test, since the pregnancy hormone is detected in the urine fifteen days after conception and not before. If we test before the date, the test is likely to be a false negative. Therefore, you should expect to have a delay of at least one day.
There are tests capable of detecting the pregnancy hormone from the first week after conception, that is, before menstruation should have come, but remember that in this week the amount of pregnancy hormones tends to go unnoticed by most of the tests.
try to buy a test that is as sensitive as possible, that is, it detects the lowest concentration of hCG. Most detect from 20 mIU / ml (International milliUnits per milliliter of urine).
Women with regular cycles
For women with regular cycles, it is easier to calculate the right time. As expected, the woman has ovulated in the middle of the cycle and the implantation of the embryo has occurred between six and ten days after fertilization. Therefore, with a delay of one day in the expected date for the arrival of menstruation, the levels of the hormone chorionic gonadotropin (hCG), which begin to rise after implantation, will already have reached a detectable level in urine.
Therefore, although there are tests that promise a result from the first week after conception, the most reliable thing is to do it at least one day late. Although it can be done at any time of the day, it is also recommended to use the first urine of the day, which has a higher concentration.
There are women with irregular periods who may have gotten pregnant later than they think and the test can give a false negative. If so, and you suspect that you may be pregnant, you should repeat the test a few days later.
Women with irregular cycles
For women who do not have a regular cycle, the detection of pregnancy is a bit more complicated than for the previous ones. There are very intuitive women who are certain that they are pregnant even before the pregnancy test confirms it, but since not all are capable or need scientific confirmation, almost all resort to the pregnancy test.
Taking the test a day late may be too early to get a reliable result. You may have ovulated later than you thought, so it is recommended to obtain a reliable result is to perform the test one week after the expected date for your period.
How to do the pregnancy test
Almost all pregnancy tests can be performed at any time of the day, but for greater safety it is recommended to do it with the first urine in the morning, which is the one with the highest concentration of hormone.
If you follow the manufacturer’s instructions, you will see that the procedure is very simple and practically does not lead to errors. You must unwrap the test, remove the cap from the test strip and place it for 5 seconds in direct contact with the urine while you pee. Once the urine has been collected, you must cover the test again (it is important that it does not come into contact with any other substance), place it on a flat surface and wait 3 to 5 minutes to read the result.
The marks of the test can be more or less intense which can indicate in some cases the time of pregnancy. But anyway, even if the intensity of the lines is low, the result is positive.
The test cartridges have an absorbent strip that reacts when the presence of chorionic gonadotropin (hCG), the pregnancy hormone, is detected in the urine, causing the strip to take on color.
Some tests have a control strip that, when reacting, indicates that we have performed the test well.
Buy pregnancy tests
When choosing a pregnancy test, you have different presentations. There are the simplest ones that consist of test strips that you must introduce in a container with the urine, which you can get 20 tests for 8.99 euros.
You can also get the most used ones that consist of a plastic device that incorporates a test strip and we can read the pink bands in the reading window. They can be obtained for around two euros a unit.
And finally, the most sophisticated early detection that can be performed from the day your period should arrive for 6.30 euros or the digital test with a week indicator for 17.31 euros.
False negatives in the pregnancy test
As you know there are false negatives in pregnancy tests. That is, if the result is negative but menstruation does not appear, it is definitely not negative. You must repeat the test after five or six days.
On the other hand, if it is positive, it is certain that you are pregnant. Except in the case of ectopic embryos (those that occur outside the uterus) or anembryonated pregnancies (without an embryo), which although they raise the levels of the hormone, pregnancy is not real.
The most important thing is that before taking the test you read the instructions very carefully, since there are several types of tests on the market.
