Pregnancy tests work by detecting the hormone human chorionic gonadotropin (hCG) in urine or blood. However, it takes time for hCG to build to detectable levels, meaning women often need to wait until they can receive an accurate pregnancy test result.<\/p>\n\n\n\n

Are you ready to take a pregnancy test or wondering about the best time to do so? Contact HOPE Pregnancy Center<\/a> in Philadelphia, PA. We can answer your questions and help you find out whether you\u2019re pregnant.<\/p>\n\n\n\n

Read on for more details about pregnancy tests and answers to common questions.<\/p>\n\n\n\n

When Will a Pregnancy Test Give an Accurate Result?<\/h2>\n\n\n\n

Pregnancy test accuracy is extremely dependent on timing. If you take a pregnancy test too early, you could receive a false-negative result because hCG hasn\u2019t built up enough yet. <\/p>\n\n\n\n

Even though early pregnancy tests claim to deliver accurate results before a missed period, the accuracy is not 99%. For instance, ClearBlue\u2019s Early Detection test is only 77% accurate<\/a> six days before a missed period.\u00a0<\/p>\n\n\n\n

For the best chance at an accurate result, wait until after you\u2019ve missed your period to test.<\/p>\n\n\n\n

Can Stress Delay My Period When Waiting to Miss?<\/h2>\n\n\n\n

Yes! Some women can become very stressed about a potential pregnancy, leading to a delayed period<\/a> that seems like a missed period. Try to relax when you are waiting to see whether or not you\u2019re going to miss your period.<\/p>\n\n\n\n

What if I Miss My Period, But I Get a Negative Pregnancy Test Result?<\/h2>\n\n\n\n

If you miss your period but then continue receiving negative pregnancy tests, you can wait a few more days or a week and test again to see if it becomes positive. If your period still doesn\u2019t arrive, you may want to visit a medical professional for further investigation. <\/p>\n\n\n\n

You could be experiencing an irregular period, or you may need a blood test to confirm pregnancy.<\/p>\n\n\n\n

Are False-Positive Results Possible?<\/h2>\n\n\n\n

Yes, but false-positive results are rare<\/a>. They could happen due to issues with the ovaries, menopause, or taking fertility medications.

While not technically \u201cfalse,\u201d you could receive a positive test at first to signal the start of a pregnancy, followed by a negative test that indicates you are experiencing an early pregnancy loss. If you receive a negative test after a positive one, see a healthcare professional for evaluation.<\/p>\n\n\n\n
