Since 1970s, the small plastic pregnancy test kits have helped in finite woman test their pregnancy status and are believed to provide 97% to 99% accurate result. Since these are devices with no brains of their own and hence can even provide false results in certain situations. They can provide both false negative and false positive results as well.
Although the machine itself is working fine but there other factors responsible for such outcomes and hence it becomes imperative for you to understand what went wrong that the kit gave a negative result. This article outlines 10 main reasons due to which a woman can receive a negative pregnancy test result even though she was expecting otherwise.
This is one of the obvious reason that the kit has produced a negative test result. When a woman is not pregnant then her urine will contain very low level of human chorionic gonadotropin also known as hCG hormone or she might not produce hCG hormone at all. The kit is designed to check for the hCG hormone levels and only if it is at the desired level the kit will show positive. Obviously a negative test result would be disappointing for woman who are planning for their baby and trying to conceive.
Since these test kits are told to have more than 97% accurate result and it would be obvious for most woman to factually believe that result.
However if someone is using the kit for the first time there is high possibility that it might not have been used properly as per the instructions. While performing such test a woman should ensure that she does not contaminate the test strip maybe buy any oil or cream present in her hand or by placing the strip on a dirty counter.
However if a woman is sure enough that she would be expecting and has still received a negative result then she need to rethink about various other possibilities because of which that might had happened. If the woman has a doubt of any other health issues or some kind of sexual disease which might have inferred with the test then she should take an appointment with her primary gynecologist for further course of action.
Testing Very Early
This is also one of the prime reason that the woman might receive a false negative pregnancy test result. Out of curiosity and anxiety see might test too early and the kit will fail to deliver the desired result. The level of hCG hormones for it to be detected by the kit require some time.
A woman must wait 14 days after she has conceived and for some it might even take couple of weeks. Every woman has a different kind of body and they all produce hCG hormones at different intervals. Some woman might even need to wait for at least 6 to 8 weeks for the kit to be able to perform the test successfully. In fact most off over the counter test kits are designed to be performed and the used only after the woman believe she has missed her period. In these cases it is recommended to repeat the test after couple of more days.
It is recommended that you should take up the pregnancy test after the first day off your missed period and some might even need to wait at least for a week as well.
Hence if a woman is sure enough that she will have conceived and see should be pregnant then this could be a reason that she is testing too early. If it is just two weeks since she had the sexual intercourse than for sure she's doing the test very early. If you want to test for your pregnancy early than it is recommended to visit your doctor and get a blood or urine test done at the lab.
Miscalculating Period Cycle Date
Woman who have no health issues and experience regular periods accurately know about their menstrual cycle. Any woman which has always had a regular period can with hundred percent certainty tell you her next date. However a lot of woman experience irregular periods and they might need to wait extra longer to perform such test as a delaying periods can be a normal thing for them. Such woman remain uncertain with a little speculation until they do not receive their periods.
The body of the woman itself starts to give various signals that can tip her off about her pregnancy. If a woman is pregnant but receives a negative test result then she would for sure start developing nausea in next six weeks or so. And if in case she is not pregnant than for sure she would soon have periods and for some it can even take several weeks for the discharge to occur.
Another reason for this could also be that a woman might have suffered with any kind of health issues recently or she might have started to undertake extra physical work which has disturbed her body. Under such conditions woman should wait for at least three or four more weeks and this time the test might result in positive if she still not receives her periods.
Many laws have been framed and implemented by government and all the companies who manufacture health devices need to abide by them. The firms manufacturing over the counter pregnancy test kit have to ensure the accuracy, safety and effectiveness of them. Although it is very rare for a kit to be defective, if it has been manufactured by a reputed organization, still there are chances that a defective test kit might reach the local pharmacy store.
If the person testing has no reason to doubt the effectiveness of the outcome of the test result then she might not think that the kit can be defective as well. Many medical experts tell that most woman would require more than one test to satisfactorily know the real situation. A negative test can turn positive and a positive test can turn negative after couple of days. Before using the test kit you should cross verify the color and the condition of the test kit. If you feel the packet has been tampered are damaged than the kit might have been compromised and it will not give you accurate results. Also check the test kits expiration date and thoroughly inspect it before usage.
Although most of the medications not related to pregnancy do not infer with the levels of hCG hormone but we cannot ignore the possibility of such situation. A woman might be prescribed a medicine for any other health issue and there are high chances that the medicine can infer with the result of your pregnancy test. If the test result is not as per your expectations it would be good to contact your doctor that if the medicine he or she has prescribed can be the reason for the same. She can also ask her doctor that whether these over-the-counter pregnancy test kit would be effective under such situation or she would need to consult her doctor and get a urine or blood test performed.

Hormone-based medicines can be prescribed for in finite types of illness and they are very common in thyroid related issues. Similar are the medicines used for neurological illness. In these cases a blood test would be a better way to approach.
Any kind of hormonal imbalance can effect the outcome of a pregnancy test. A woman might not even be aware of that she has a hormonal imbalance until she is properly tested by her doctor. As we grow old our body goes through lot of hormonal changes. For example our skin starts to become dry with our age which is because slowly the development level of estrogen decreases in our bodies.
A woman suffering with any kind of un-diagnosed thyroid disease can believe that she is pregnant because she might have a bloated stomach or she could have missed her periods because of that. There could be n number of health-related issues due to which a woman can gain weight, experience fatigue and might develop symptoms similar to those of early pregnancy. So if in case a woman would have been expecting a positive result but even after several tries the kit does not conform same than the woman might need to see a doctor to check for other kind of issues.
A woman white not be aware that she is infertile. If a woman is trying to become pregnant for the first time she would always think that she's hundred percent capable to conceive. She might ignore the first few failed attempts and would keep on trying to get pregnant for many months or even years before she would be able to understand that there is some other problem with her productive system. Only after she gets a negative test result each and every time she is expecting a positive result, she would understand that there could be some other underlying problem.
However there is nothing to panic about because not of researches have been done and now they are several advanced medicines available which can cure infertility. The medicines can help your body to ovulate regularly, however it might take couple of months for you to be able to conceive. Although the test kits will not be able to work under such situations but these prove to be beneficial because had the woman would not have performed these tests she would have never known about her infertility. It is a sad situation but if timely attended by a doctor and if the doctor is equipped enough to provide you with the required medication than within couple of months you can become a mother.
Not Testing Early in Morning
These pregnancy test needs to be performed as the first thing in the morning. The first urine of the day that your body excretes contains the highest level of hCG hormone and as the day passes your urine starts to get diluted. The first urine of the day is the most concentrated one. Because while you are sleeping you do not drink any kind of water or coffee or juice than the first urine of the morning is believed to have adequate level of hCG hormone for your kit to detect.
Your kidneys have been working throughout the night and they would have filtered out anything that could hamper the quality of hCG hormones present in your urine. So if in case you are taking any other kind of medicine than that would also have been filtered out by your kidney and would not impact the result of the pregnancy test kit if you take it early morning. The more you delay the more diluted your urine will become and hence it will become more unlikely for your test kit to give accurate result. Any kind of liquid present in your diet can jeopardize the result.
Lot of women who miss their periods presume that there periods might have been delayed by couple of days due to obvious reasons. However when they actually start to have heavy periods later they understand that there is some problem. The woman might believe it to be normal because of a delay in the cycle but in actually they might have miscarried. Data states that a miscarriage happens in at least 25% of all pregnancies worldwide and most of them do not even know that they have miscarried. Various women's have complained that there test have converted from positive to negative after couple of days. Miscarriage is the prime reason for that. In these situations negative results do not mean that they are not pregnant but actually it might be an early sign of miscarriage.
Some women also keep on repeating the test over next couple of weeks just to ensure that the pregnancy is moving smoothly. Hence if even after couple of weeks the test stays positive as it was on the first day than it means that the hCG levels are being produced at the optimum level. If a woman would have to suffer with the miscarriage then she would do so within first few weeks. That is why most woman confuse miscarriage with delayed periods. Sad part being that the doctors can not prevent these miscarriages but if the woman sees her gynecologist early then she might be able to check for any complications to prevent any kind of miscarriage in the future.
Last but not the least ectopic pregnancies are also one of the reason for the negative pregnancy test result.

Although true but these pregnancies account for just 1 or 2% of the overall pregnancies worldwide. These pregnancies are more common in older woman who are about 40 years in age.

The early symptoms of a normal pregnancy could be like skipping the periods or having fatigue and nausea but the symptoms of ectopic pregnancy are much more harsh and they can easily alert the woman that she requires immediate medical help. If the pregnancy test result was negative but the woman has an ectopic pregnancy then she would feel pain in the lower side of her abdomen. She might also see spots or experience light bleeding even though her menstrual cycle date is not yet arrived. And ectopic pregnancy requires immediate surgery and the fertilized egg needs to be removed from the Fallopian tube.
