Negative test and pregnancy. Can a test not show pregnancy?

Pregnancy is always an exciting issue. There are cases when it can occur even with a negative test. Each woman should carefully monitor her health and turn to the slightest signs of malaise, unpleasant symptoms or unusual discharge.

Is pregnancy possible with a negative test?

To determine the situation of a woman: is she pregnant or not capable of a test, oriented to calculate the level of hormones in female blood. The name of this hormone is chorionic gonadotropin, abbreviated simply “hCG”. To calculate its concentration in the blood, the very next day after fertilization, when the fertilized female cell attaches to the wall in the uterine cavity. You can determine the amount of hormone in several ways.

The simplest, affordable and popular way is a test that is easy to purchase at any pharmacy. It is sold without a recipe, the principle of its action is quite simple and is not at all expensive (in international currency its cost starts at only $ 1).

The principle of operation of such a test is quite simple: there is a substance on the stick - certain antibodies that interact with the hormone of the “pregnancy” located in the urine of a woman and take the result of their interaction to the white field:

• if the strip is one -there is no hormone in the urine
• if there are two stripes -in the urine, the concentration of the hormone is observed and this means that the fetus is in the uterine cavity

It is possible that the test can show incorrect information. This happens most often because manufacturers produce not high -quality tests or a defective product.

• It often happens that the pregnancy is present, but the test gives a negative result. This may even have several tests in a row and the reason for this is not at all a quality product, but a physiological feature of the human body
• The fact is that immediately after conception, a fertilized egg may not attach to the wall. At her disposal for this action ten days and all this time she can calmly be in the cavity
• Only when the cell is attached, does it form a peculiar protective shell - the placenta. It is the placenta that produces this "pregnant" hormone. Based on this, we can conclude that pregnancy tests are effective only after a week or even two weeks after conception
• Unknown women often make hasty conclusions when they make a test for the second or third day and wait for the result

The best time to spend the test is a delay in the expected critical days. The delay, by the way, may also not mean pregnancy at all, it is important to know that up to five days of delay are considered normal.

There are several important recommendations aimed at making the test correctly:

• choose a test of a well -known manufacturer having many positive reviews and extensive work experience
• always buy two tests at once, in case one of them turns out to be poor -quality
• if you buy two tests at once, preferably buy a product of different brands
• test the urine that was collected in the morning - it has the maximum concentration of biological components
• read the instructions carefully and only then dip the test in the urine, pay attention to the correct side of the dipping and the necessary level of level
• do not hold the urine test for too long, each manufacturer indicates the exact time of its dipping
• after you dipped the test, put it on a dry surface and exactly wait for the time through which the result should appear

Negative test: Is an ectopic pregnancy possible?

• Gynecologists are not rarely diagnosed in women an ectopic pregnancy thanks to the test. Of course, the most accurate result can only be obtained with the help of thorough diagnosis and ultrasound, but still there are certain skills and knowledge that helps to avoid rupture of the phallopian pipe and avoid serious consequences
• Pregnancy, which occurred, is very similar to normal, but it differs in that the fetal egg was attached not to the fallopian wall but in the pipe leading to the uterine cavity. In this case, a hormone is also produced, but a little in smaller quantities and even an embryo develops. However, such a fruit is doomed to death, because its development is not normal and pathological
• It is worth noting that with such a pregnancy, the hormone level rises a little later than with normal, about one to two weeks. But this is not significant when a woman does not know about her pregnancy and guesses about this only when a significant delay comes

Based on this, women regularly perform the test and expectant fertilization can notice the ambiguity of their dough: it shows “almost” a positive result - one strip is clear, the second translucent. If the time for the development of the fetal egg has passed enough, and the test does not give bright two stripes, you should consult a doctor for advice.

• The development of the egg on the pipe mucosa is not normal. Such pregnancy is extremely dangerous, it is able to cause irreparable harm to a woman and even threaten her life
• The embryo in the uterine pipe, as a rule, develops with pathologies and is doomed to death
• The fact that a woman has such a pathology is most often affected by such factors as: mature age (from thirty-five years is a kind of “risk group”), the presence of inflammatory and infectious diseases of the urine system, as well as the abnormal development of the internal ones themselves genital organs of a woman
• There is another opinion of doctors who claims that female contraception - spiral affects the appearance of this type of pregnancy -

It should be noted that an ectopic pregnancy can be in several cases, the fetal egg is attached in places abnormal for it:

• fallopian tube - The most common phenomenon that has a frequency in 99% of cases
• in the "uterine horn" -part of the fallopian tube
• in the ovary -a very rare occurrence
• in the abdominal cavity

Such a pregnancy is difficult to determine by poor health, since all the symptoms are similar to the symptoms of a normal course of pregnancy. Unfortunately, she always has the ability to burst and burst. This happens with severe sharp pains and hemorrhages in the abdominal cavity.

Monthly delay and negative test: is pregnancy possible?

Every woman at least once in her life had experience in a pregnancy test. For some, the test is of great importance and a thrill in the expectation of the appearance of a child in the family, for others-an undesirable event. In any case, when making a test it is necessary to know that there are situations when the test is capable of giving untrue or incorrect information.

In most cases, a woman begins to test when she notices the delay in her cycle. In addition to this symptom, a poor health is possible: nausea, pain, toxicosis.

It is worth noting that if the test is not done correctly or buy a low -quality test, it is quite capable of giving a false result. If you are sure that you are purchasing a quality test, pay attention to factors such as:

• its sensitivity -different manufacturers have a different degree of sensitivity of the dough, this can affect the result. Wanting to get the best result, you should buy a test, which gives 99.9% probability
• the deadline for its commission -some are allowed for use already in the first weeks, while others only after fourteen
• the time of the test -some tests allow analysis at any time of the day, while others only in the morning, when, after a long delay in urine, the largest amount of hormone is concentrated in it
• its shelf life -this is an important factor that affects the correct result during the test, if the expiration date expired, he will quite show you a false result

Remember that each organism is individual and the effectiveness of the test depends on the physiological characteristics of the woman.

Menstruation can stop not only due to pregnancy. Before making a test and suspect it, explore yourself on the presence of other factors affecting the delay:

• Climax -the hormonal failure of the body of a woman, after which the periods simply disappear. In some cases, they appear again, but after a while they can again abyss. Such sensations can last about a year
• Polycystic -the occurrence of cysts (tumors) in the ovaries that violate their normal work and affect the hormonal background
• Anemia -this is a deficiency and low level of hemoglobin blood. The woman’s body tries to preserve blood and menstrual discharge in the maximum quantity is quite scarce or may not be at all

Is it possible to do a pregnancy test with menstruation?

In women's practice, it also happened that pregnancy occurred even when the body produced bloody discharge monthly. This is the reason to worry about whether it is necessary to do a test during menstruation?

• During menstruation, a test for the definition of hCG is not prohibited. The fact is that the discharge does not affect the concentration of a "pregnant" hormone in the body
• The main thing that prevents this test is the hygiene of the process
• For this reason, before making a test during menstruation, you should use the swab
• If blood discharge enters urine, they can significantly affect the effectiveness of the test
• Attention should be paid to other signs of pregnancy and poor health of a woman: toxicosis, headaches, pain and breast pouring, cramps, changes in taste preference
• Pay attention to the nature of the discharge, if they are plentiful and strong - it is more like menstruation, and if scarce and bright red - this is quite similar to a small bleeding that occurs during implantation of the fetal egg to the wall of the uterus

In any case, you can do a test during menstruation. However, you need to know that during pregnancy, menstruation is always not good, you should see a doctor to avoid complications that this symptom can bring.

If 2 tests are negative, can there be a pregnancy?

It does not rarely happen that before pregnancy, a woman repeatedly performs tests and all of them turn out to be negative. To her surprise, after time, she will find out that she was still pregnant. What is the reason for such negative tests?

As a rule, many factors affect the effectiveness of the test and the negative result is able to show:

• expensed test - in which active substances have become unusable because a lot of time has passed since manufacture
• an unexpected test -it acts only when a lot of time has passed since the fertilization and to get the most accurate result, you should choose a test with 99% of truthfulness
• taking certain medicationsat the time of the test, in this case we are talking about hormonal drugs
• incorrect use of the testallows you to find out the wrong result

After the test showed you a negative result several times, but over time you found pregnancy with a blood test or ultrasound, you should consult a doctor for advice.

The ovulation test is negative, is pregnancy possible?

• The ovulation test is significantly different in its principle of action. If, in case of fertilization, the test determined the presence of a woman of chorionic gonadotropin in the body, then the ovulation test is aimed at calculating whether the egg was released into the uterine cavity
• There are two types of such tests: strips and cassettes. Cassettes are more sensitive and they give a woman more accurate information. They differ in that they cost much more than ordinary strips
• This test also requires dipping him in urine. There are also reusable tests with a set of several strips

As a rule, the ovulation test shows the concentration of the hormone of estrogen, which is present in the body, focusing on the state of the egg. When the egg goes into the uterine cavity, its amount is as much as possible, which means that the most favorable time has come to conceive the child.

If the ovulation test shows a negative result, then there is no probability of getting pregnant. However, every woman needs to know that male seed is able to live in the uterine cavity for up to two to three days and if after this time the egg nevertheless drops into the cavity and there will be a viable sperm-pregnancy is possible.
