Pregnancy begins with the meeting of two cells, a sperm (Semen) and an egg (Occyte), and after nine months, or more precisely after 40 weeks, and if all the appropriate conditions are available, a healthy and healthy baby will be born to the outside world.

| pregnancy test |
A pregnant woman goes through a lot of changes, both on the physical level and on the psychological level, and many women said that they knew and felt pregnant from the stage of fertilization of the egg or only a few days after.
In addition to these feelings, there are a number of simple tests that allow us to know for sure whether there is a fetus in the womb or not. One of these simple and inexpensive tests that are available to all segments of society is the home pregnancy test .
The pregnancy test is based on exploiting the scientific fact that indicates the start of secretion of the pregnancy hormone (hCG) into the woman's blood circulation at the beginning of pregnancy.
This hormone is secreted only during pregnancy and not in any other case, which enables us to rely on this test reliably and assuredly to check for pregnancy.
When is the examination performed?
It is preferable to perform the examination in all cases in which we suspect that pregnancy has occurred, whether this is after having sexual intercourse without using contraceptive methods or following a delay in the menstrual cycle.
It is not necessary for the woman to undergo the examination, but the importance of the examination lies in enabling the woman to know that she is pregnant from the early stages, which allows her to change her habits accordingly, such as: stopping smoking, stopping drinking alcohol, and other habits.
The home pregnancy test device cannot detect pregnancy immediately after the fertilization of the egg, so there is no point in conducting it immediately or shortly after sex, but on the other hand, it is able to detect pregnancies two or three days before the next menstrual period.
If the result of the home examination is positive, the woman must take a blood test at the gynecologist in order to confirm the result conclusively.
Pregnancy can also be detected by performing a blood test. The results of the blood test are obtained as a numerical value indicating the amount of the pregnancy hormone in the blood, as the level of the hormone increases as the pregnancy progresses.
The at-risk category
Since we are talking about a normal urine test , which aims to detect a specific hormone, the high level of the hormone in the urine increases the credibility of the test, so when pregnancy is analyzed during an early stage of it, the result can be negative despite the actual pregnancy, but on the other hand If the pregnancy test is positive, pregnancy is confirmed in such a case.
How to perform the examination
The market is full of several types of home examination devices, the price of which is the central difference between them, but the majority of the types are very reliable in terms of results. .
The examination is done by urinating into a cup and dipping what looks like a plastic stick into the cup for several seconds, after which one must wait for several minutes. The number of minutes of waiting varies according to the different type of examination device until the woman gets an answer to her important question, which is whether she is pregnant or not?
It should be noted that there is no need to prepare in advance before performing a home pregnancy test, all a woman needs is a few drops of urine.
Analysis of the results
Possible results depending on the type of examination include the following:
1. Home pregnancy test
After dipping the test stick in urine, one or two lines appear on the stick. The first line that appears is the test line, and it always appears whether there is pregnancy or not. Only one line is a negative test result, indicating that a pregnancy has not occurred or that the test was done early.
If two lines appear, it means that the test result is positive and the woman is pregnant.
2. Blood test
Pregnancy can also be detected by performing a blood test. The results of the blood test are obtained as a numerical value indicating the amount of the pregnancy hormone in the blood. The test is done by drawing a blood sample from a vein.
