#2: Incorrect Technique While Testing

You should read the user instructions from the manufacturer carefully to make sure using the pregnancy test correctly. The time to take the test may affect its result. Taking a pregnancy test at night is not recommended as it can deviate the actual hCG level in your body. You should place the stick in the first urine passing in the morning right after you wake up because it is time you have the highest hCG concentration.

Take detailed note of whether you have one midstream or standard test which you need to dip your pregnancy test stick into your urine. It will take a maximum of 3 minutes, and you can read its results in the next 7 minutes. After that, the result will be invalid.

In some particular case, HCG levels can still be found in your urine after your pregnancy ended in the miscarriage. And you have to wait several weeks until the level of HCG drops.

#4: Ectopic Pregnancy

When your fertilized egg did not implant into your uterus, the action of such egg implanted in your fallopian tubes is called the ectopic pregnancy.

If you fall into this circumstance, you should repeat the test after a few days to create the sufficient time for the levels of HCG to increase. Due to such rapidly rising hCG concentrations in a pregnant woman, the negative result two week after your missed period can be fairly accurate.

#6: Misreading the Test

When the urine actually evaporates from your test strip, only 1 colorless line may appear on your strip window which is mistaken as the positive result. As the pregnancy tests are indeed designed to change the color for the positive result, you should wait until the required time to read the exact results. You also should discard the stick as well as never reuse, regardless of your result.


Apart from the accuracy, sensitivity level, and price of the pregnancy test, the expiry date can be the critical factor after selecting your correct test. You may not be sure of your final result if using the expired pregnancy test. The most important thing you may look at while buying the pregnancy test can be to check the expiration date.
