Waiting to find out whether you’re pregnant can feel like a long time—especially when the pregnancy wasn’t planned. You may be wondering how soon you can take a pregnancy test and whether you can trust the result.
The timing of your test matters. Testing too early can sometimes give you a negative result even if you are pregnant.
Here’s what you need to know.
When Should I Take a Pregnancy Test?
For the most reliable results, it’s generally best to take a home pregnancy test after the first day of your missed period. Some tests claim they can detect pregnancy earlier, but the earlier you test, the greater the chance of getting a false-negative result.
If your periods are irregular or you aren’t sure when your next period is due, knowing when to test can be more difficult. The Office on Women’s Health recommends waiting at least four weeks from the time you had sex if your cycles are irregular and you aren’t sure when your period should begin.
How Does a Pregnancy Test Work?
Pregnancy tests look for a hormone called human chorionic gonadotropin, or hCG.
Your body begins producing hCG after implantation occurs. During early pregnancy, the amount of hCG increases quickly. A urine pregnancy test detects this hormone in your urine.
If you test very early, there may not yet be enough hCG in your urine for the test to detect. That’s one reason a pregnancy test can be negative even though you are pregnant.
Can I Get a False-Negative Pregnancy Test?
Yes. A false negative means the test says you are not pregnant when you actually are.
This can happen if you:
- Take the pregnancy test too early
- Don’t follow the test instructions correctly
- Check the results too soon
- Use urine that is too diluted
If you receive a negative result but your period still doesn’t begin, wait a few days and test again. If you continue getting negative results but still think you may be pregnant, contact your healthcare provider.
What If My Pregnancy Test Is Positive?
If your pregnancy test is positive, you may immediately have questions about what to do next.
You don’t have to make every decision at once.
An ultrasound can provide additional information about your pregnancy that a pregnancy test cannot, including where the pregnancy is located, whether fetal cardiac activity is detected, and measurements that can help estimate how far along you are.
Having accurate information about your pregnancy can help you better understand your next steps.
