Waiting to take a pregnancy test when you think you may be pregnant can be excruciating. If you’ve recently had unprotected sex or experienced contraception failure, you probably want to know as soon as possible. Show
Before you begin to worry or make any plans, taking a home pregnancy test is a good first step. Of course, if you want to skip the home test, make an appointment When Should You Take a Pregnancy Test (For Best Results)?Option 1: Before You Miss Your PeriodThe earlier you take a test, the less accurate it will be. Taking a test before you miss your period or less than two weeks after sex can cause a false negative. Some women take a test too early and assume they are not pregnant. This can be especially confusing if a woman spots or bleeds during her first trimester, making her believe she had her period. We see clients who are already entering their second trimester by the time they notice more obvious pregnancy symptoms and are shocked to find out they are pregnant. Option 2: Two Weeks LaterMany women test according to the “two weeks” rule. This can provide accurate results for women with a predictable 28-day cycle and who ovulate once at a regular interval. However, some women’s cycles are not as predictable, or medications such as birth control and antibiotics can change their cycle and ovulation date. Stress can also cause interruptions in a regular or typically predictable cycle. Option 3: After You Miss Your PeriodThe best time to take a pregnancy test is when your period is supposed to start or after you realize your period is late. If your results were still unreadable or inconclusive, retake another pregnancy test the next day. For more accurate results, take the test when you first wake up. The hCG hormone is higher and more concentrated in the morning. If the test is negative, but you still think you may be pregnant, wait a few more days and test again. HCG nearly doubles about every two days in early pregnancy. If the results are inconclusive (or the results are positive, but you’re still unsure), make an appointment with us and know for sure.

If you’re trying for a baby — or desperately trying to avoid getting pregnant — you’re likely wondering how soon you can take a pregnancy test. While today’s new and improved home pregnancy tests offer results faster than ever before, inaccuracies can still occur if they’re not used properly. “I used one of those early pregnancy tests with my daughter, and turns out, there’s such a thing as too early,” says Jennifer Higgins, of New York. “I tested six days before my period was set to start — just like the box said — and got a negative result, even though I was, in fact, pregnant!” From how soon after sex to take a pregnancy test (and the best time of day) to the reasons behind false negatives, here’s everything you need to know about taking a home pregnancy test. How soon can you take a pregnancy test after sex?When you’re worried about an unwanted pregnancy after unprotected sex (or contraception that went awry), it’s only natural to want to test as early as possible. But for the most accurate results, you want to wait at least 12 days after intercourse, or three weeks if you have an irregular period. Pregnancy tests work by detecting the hormone human chorionic gonadotropin (hCG), which the body only begins producing after implantation (when a fertilized egg attaches itself to the lining of uterus). Typically, this occurs six to 12 days after you’ve ovulated. “If you’re comfortable with the fact that you might get a false positive, you can take a home pregnancy test just 10 days after unprotected sex,” says Dr. Felice Gersh, a board-certified OB-GYN. “Sometimes pregnancy tests will turn positive by then. But keep in mind, that still is on the early side.” When to take a pregnancy test during your cycleEven though some early pregnancy tests claim to be able to detect hCG over a week before menstruation is supposed to begin, you should proceed with caution when testing before your period is due. “A woman can run a pregnancy test on herself at any time in her cycle, but it’s accuracy is always dependent on the quantity of hCG that’s present in the urine,” says Gersh. “In other words, if you’re pregnant and test too early, it can give you a negative result. Waiting an additional week after a missed period to test will substantially reduce the chance of a false negative.” When is the best time of day to take a pregnancy test?Although late-night, panic-induced drugstore runs aren’t unheard of when it comes to pregnancy tests, it’s best to wait until morning. “Home pregnancy tests are best taken right after waking up, since that’s when the concentration of hCG is highest in the urine,” says Dr. Kecia Gaither, an OB-GYN, maternal fetal specialist, and the director of perinatal services at NYC Health and Hospitals in New York. To increase the accuracy, Gersh advises waiting to drink any fluids until after you’ve taken the test. Causes of a false negative pregnancy testIn addition to testing too early in your cycle, other potential causes for false negatives are:
It’s also important to keep in mind that while home pregnancy tests are just as accurate as the urine tests you get in the doctor’s office, they’re not as effective if they’re expired. Always check the expiration date before taking a pregnancy test to make sure it’s up-to-date. Causes of a false positive pregnancy testWhile too-early testing can result in a false negative, it’s “very, very rare” to get a false positive, according to Gersh. However, false positives aren’t completely unheard of. Here are a few causes:
What does a faint line on a pregnancy test mean?If you’re straining to make out what appears to be a faint line on your pregnancy test, there’s a good chance you’re pregnant. “Faint lines are generally indicative of a very early pregnancy,” says Gaither. If you were inclined to take another test a few days later — just to be sure — you wouldn’t be alone. “With my first pregnancy, the line was super-faint when I first tested, so I wasn’t sure if it counted as a positive,” says Krysten Mace, of Cranford, New Jersey. “Sure enough, though, when I tested the following day, that second line was unmistakable.” How accurate are pregnancy tests?As long as it’s not expired, and it’s being used the proper way (at the proper time), home pregnancy tests are about 97% accurate. “The drugstore urine pregnancy tests are just as effective as the ones taken in your physician’s office,” says Gaither. That said, you can have a blood pregnancy test done at your doctor’s office, which can detect hCG earlier than a urine test. Depending on whether or not there’s a lab on-site, results can take anywhere from a few hours to a few days. Signs you may be pregnantIf you haven’t gotten your period and are experiencing any of the following early pregnancy symptoms, you may want to take a pregnancy test:
If the test is negative and you still haven’t gotten your period, keep in mind there are a number of factors besides pregnancy that can contribute to a late period or irregular cycle, including:
Additional health conditions that may cause a late period include:
Whether you’re hoping to be pregnant or not, having a late period can be nerve-wracking. Thankfully, home pregnancy tests can offer quick answers without a trip to the doctor when used properly. That said, if you’re unsure about your results or have questions, it’s always smart to speak with your health care provider. |
