A pregnancy test can typically detect the presence of the pregnancy hormone human chorionic gonadotropin (hCG) in your urine as early as 10 days after a missed period. However, the accuracy of the test can vary depending on several factors, including the sensitivity of the test, the timing of the test, and how closely you follow the instructions for taking the test.
It is generally recommended to wait until you have missed your period to take a pregnancy test, as this is when the levels of hCG in your urine are likely to be high enough to detect. However, some tests are sensitive enough to detect hCG earlier, so it is possible to get a positive result before you have missed your period.
If you think you might be pregnant and want to take a pregnancy test, it is important to follow the instructions on the package carefully and to wait until you have missed your period to take the test. If you get a negative result but still think you might be pregnant, you should wait a few days and take the test again. If you get a positive result, it is a good idea to confirm the result with a healthcare provider.
Can a pregnancy test be wrong?
Yes, it is possible for a pregnancy test to give a false result. There are several reasons why this might happen, including the following:
- Using the test incorrectly: It is important to follow the instructions for taking the pregnancy test carefully. If you do not use the test correctly, you may get a false result.
- Testing too early: Pregnancy tests are typically most accurate when taken after you have missed your period. If you take the test before the levels of the pregnancy hormone human chorionic gonadotropin (hCG) in your urine have reached a high enough level, you may get a false negative result.
- Using a test that has expired: Pregnancy tests have an expiration date, and using an expired test can result in a false result.
- Certain medications: Some medications, such as certain fertility drugs and some psychiatric medications, can interfere with the accuracy of pregnancy tests.
- Medical conditions: In rare cases, certain medical conditions, such as trophoblastic disease or certain types of cancer, can cause high levels of hCG in the body and result in a false positive result.
It is important to remember that home pregnancy tests are not always 100% accurate. If you think you might be pregnant and get a negative result, but your period is still late, you should wait a few days and take the test again. If you are still unsure about the result, you should consult a healthcare provider for confirmation.
Why do I feel pregnant but test negative?
There are several reasons why you might feel pregnant but get a negative result on a pregnancy test. These include the following:
- Testing too early: Pregnancy tests are typically most accurate when taken after you have missed your period. If you take the test before the levels of the pregnancy hormone human chorionic gonadotropin (hCG) in your urine have reached a high enough level, you may get a false negative result.
- Using the test incorrectly: It is important to follow the instructions for taking the pregnancy test carefully. If you do not use the test correctly, you may get a false result.
- Using a test that has expired: Pregnancy tests have an expiration date, and using an expired test can result in a false result.
- Certain medications: Some medications, such as certain fertility drugs and some psychiatric medications, can interfere with the accuracy of pregnancy tests.
- Medical conditions: In rare cases, certain medical conditions, such as trophoblastic disease or certain types of cancer, can cause high levels of hCG in the body and result in a false positive result.
If you are experiencing symptoms of pregnancy, such as missed periods, morning sickness, breast tenderness, and fatigue, but are getting negative results on pregnancy tests, you should consult a healthcare provider. They can help determine the cause of your symptoms and advise you on the next steps.
Why am I testing negative but no period?
There are several reasons why you might be testing negative for pregnancy but not having your period. These include:
- Pregnancy: It is possible that you are pregnant and the pregnancy test is simply not sensitive enough to detect the pregnancy hormone human chorionic gonadotropin (hCG) in your urine. This can happen if you test too early or if you are using a less sensitive test. If you think you might be pregnant and are not getting your period, it is a good idea to take another pregnancy test or to consult a healthcare provider for confirmation.
- Stress: Stress can affect your menstrual cycle and cause your period to be delayed or missed.
- Weight changes: Rapid weight gain or weight loss can disrupt your menstrual cycle and cause your period to be delayed or missed.
- Certain medications: Some medications, such as birth control pills, can alter your menstrual cycle and cause your period to be delayed or missed.
- Medical conditions: Certain medical conditions, such as polycystic ovary syndrome (PCOS) and thyroid disorders, can cause irregular periods or missed periods.
If you are not getting your period and are not pregnant, it is a good idea to consult a healthcare provider. They can help determine the cause of your missed period and advise you on the next steps.

Can 2 positive pregnancy tests be wrong?
It is generally very unlikely for two positive pregnancy tests to be wrong. Home pregnancy tests are typically more than 99% accurate when used correctly, and getting two positive results is a strong indication that you are pregnant.
However, it is possible that a rare medical condition or certain medications could cause a false positive result on a pregnancy test. In rare cases, certain medical conditions, such as trophoblastic disease or certain types of cancer, can cause high levels of the pregnancy hormone human chorionic gonadotropin (hCG) in the body and result in a false positive result. Some medications, such as certain fertility drugs and some psychiatric medications, can also interfere with the accuracy of pregnancy tests.
If you have taken two positive pregnancy tests and are experiencing symptoms of pregnancy, such as missed periods, morning sickness, breast tenderness, and fatigue, it is highly likely that you are pregnant. However, if you are still unsure about the result, it is a good idea to consult a healthcare provider for confirmation. They can perform a more sensitive pregnancy test or an ultrasound to confirm the pregnancy.
What is the best pregnancy test?
There is no one “best” pregnancy test as different tests may work better for different people. Some factors to consider when choosing a pregnancy test include:
- Sensitivity: The sensitivity of a pregnancy test refers to the lowest level of the pregnancy hormone human chorionic gonadotropin (hCG) that the test can detect. The more sensitive the test, the earlier it can detect pregnancy. If you want to take the test as soon as possible, you may want to choose a more sensitive test.
- Accuracy: Most home pregnancy tests are more than 99% accurate when used correctly. However, it is still possible to get a false result, so it is important to follow the instructions for taking the test carefully.
- Convenience: Some pregnancy tests are easier to use than others. For example, some tests require you to collect a urine sample and then dip the test strip into the sample, while others allow you to hold the test strip directly in your urine stream. Consider which method is most convenient for you.
- Cost: Pregnancy tests can vary in price, so consider how much you are willing to spend.
It is generally recommended to choose a reputable brand and to read reviews or ask for recommendations from a healthcare provider or pharmacist. It is also a good idea to follow the instructions for taking the test carefully to ensure the most accurate result.
Can I take a pregnancy test at night?
Yes, you can take a pregnancy test at night. Pregnancy tests work by detecting the presence of the pregnancy hormone human chorionic gonadotropin (hCG) in your urine. The levels of hCG in your urine are typically highest in the morning, so it is generally recommended to take a pregnancy test in the morning when your urine is most concentrated. However, you can take a pregnancy test at any time of day, and the result should be just as accurate.
If you are taking a home pregnancy test, it is important to follow the instructions on the package carefully. This may include collecting a urine sample in a clean, dry container and then dipping the test strip into the sample or holding the test strip directly in your urine stream. It is also important to wait the recommended amount of time for the test to work before reading the result.
If you are unsure about the result of the test or if you have any concerns about your health, it is a good idea to consult a healthcare provider. They can perform a more sensitive pregnancy test or an ultrasound to confirm the pregnancy and provide you with more information and guidance.
