Pregnancy tests are a reliable way to confirm pregnancy, but sometimes the results can be confusing. It’s possible to get a positive test result followed by a negative result. This can be alarming, but there are a few reasons why a second pregnancy test might be negative after a first positive test. Here’s what you need to know.
Reasons for a Negative Pregnancy Test
The first test was a false positive. This is not as common as a false negative, but it can happen. False positives can occur if the test is not used correctly, if the test is expired, or if there is another medical condition that causes a false positive result.
The pregnancy is very early. It takes time for the levels of hCG (human chorionic gonadotropin), the hormone that pregnancy tests detect, to rise in the blood. If you took the first test very early in your pregnancy, it is possible that your hCG levels were not high enough to be detected by the test.
You had a miscarriage. It is possible to have a miscarriage very early in pregnancy, even before you know you are pregnant. If you had a miscarriage, your hCG levels would drop, which could result in a negative pregnancy test.
What to Do if You Have a Negative Pregnancy Test
If you took two pregnancy tests and the second one was negative, it is important to talk to your doctor. They can help you determine the cause of the negative result and recommend the next steps. Here are some additional things to keep in mind:
Wait and Test Again
Wait a few days and test again. It is possible that your hCG levels have not had enough time to rise.
Use a Different Brand of Test
Use a different brand of test. Some pregnancy tests are more sensitive than others. If you used a less sensitive test, it is possible that your hCG levels were too low to be detected.
See Your Doctor
See your doctor if you are still experiencing pregnancy symptoms, such as nausea, fatigue, or breast tenderness, even if the second test was negative. They can perform a blood test to confirm your pregnancy status.
Why could the first pregnancy test be positive and the second test not be positive?
When taking a pregnancy test while trying to get pregnant, time can seem to stop. Even though you know you are only waiting a few minutes, it feels like time has stopped and the world is frozen, making it impossible for the test to go either way. When the test results are positive, you are overjoyed and rush to get another one to “make sure” the first one was accurate. If the second test comes back negative, does that mean you are not pregnant?
There are very few false positive pregnancy tests
This means that if you take a pregnancy test and it comes back positive, you are probably pregnant.
- You’ve recently been pregnant and are miscarrying.
- You have an ectopic pregnancy (a pregnancy that isn’t in your uterus — it’s rare but possible).
- Other serious hormonal issues that would likely be causing other issues.
All of those things are uncommon but possible (especially if you’re not bleeding).
Therefore, it is premature to start making plans just yet, but a positive pregnancy test indicates that you are probably pregnant.

How accurate are home pregnancy tests?
Many home pregnancy tests claim to be 99% accurate. However, home pregnancy tests vary in their capacity to detect pregnancy in individuals who have just missed a period. Take another test one week after your missed period or get in touch with your doctor if you get a negative test result but still believe you might be pregnant.
Is it possible to get first positive & subsequent negative pregnancy tests? – Dr. Teena S Thomas
A negative pregnancy test after a positive test can be confusing, but there are several reasons why this may happen. False positives, early pregnancy, and miscarriage are all possible causes. If you have a negative pregnancy test after a positive test, wait a few days and test again, use a different brand of test, or see your doctor if you are still experiencing pregnancy symptoms. They can help you determine the cause of the negative result and recommend the next steps.
