For this reason, 10–20% of pregnant people will receive a false-negative result on the first day of the missed period . While it’s possible to get a positive result before your missed period, the chance is relatively small—and the chances of a false-negative are much higher . A false-negative result is when you get a negative result even though you’re pregnant . Sometimes an egg will implant briefly but will not be sustained. This is also called a chemical pregnancy – hCG is produced, but the pregnancy doesn’t continue.
Your hCG levels are most concentrated in your first-morning urine. So for the best accuracy, always take a pregnancy test in the morning. A faint line may appear if you let a pregnancy test sit for too long before reading the result. These are known as evaporation lines and can be easily mistaken for a positive pregnancy test. This is a very early miscarriage that happens before the 5th week of pregnancy.
unwanted pregnancy: is this false alarm?
In some countries, strip tests may only be available for purchase online . In the USA for example, you may be able to purchase pregnancy tests at a dollar store or discount store. Your healthcare provider can also perform a blood test .

A home pregnancy test checks to see if there's HCG in the urine. During early pregnancy, the amount of HCG in blood and urine rises quickly — doubling every 2 to 3 days. That means if you wait a day or two after your missed period to take the test, and you are pregnant, it's more likely the test will find HCG and show a positive result. Mayo Clinic, it is advisable to take a pregnancy test after the first day of your missed period to reduce the chances of getting a false negative result.
You get the most accurate results if you wait up to 5 minutes, though this can vary by brand. Read the package instructions to learn exactly how long you'll need to wait to confirm a negative or positive result. Even if your pregnancy test is negative, it’s important to listen to your intuition when it comes to your body. Speak to a healthcare provider if you have any concerns about your health or menstrual cycle. A small sample of blood is drawn with a needle and sent to a laboratory . The results can take from a few hours to more than a day.
Home pregnancy tests: Can you trust the results?
We suggest waiting because the rate of early pregnancy loss is high, and it’s possible that you might have had a chemical pregnancy. Many home pregnancy tests available today are midstream urine dip tests, which are the traditional “pee-on-a-stick” tests and are fairly easy to use. There also are tests in which you pee into a cup and dip a test strip into the urine. The New York Times published a story ranking the best home pregnancy tests, citing a midstream test with an ergonomic grip as the easiest to use and most accurate. A false-positive might happen if you had a pregnancy loss soon after the fertilized egg attached to the uterine lining.
Again, your provider may not give you a blood test. Oftentimes, a positive home pregnancy test is enough to get started with the prenatal care you need. Doctors typically schedule the first prenatal visit when you're about 8 weeks pregnant.
However, the first part of your cycle is more variable than the second, making it tricky to determine the best time for an early test. Many people have irregular menstrual cycles, either longer or shorter than others. Sometimes it’s hard to remember the exact date of your last period and when to expect your next period. Between 10% and 20% of pregnant people get a negative pregnancy test because they test too early. To use an at-home OTC pregnancy test, you pee on the end of a stick, which will check your urine for hCG.
However, this actually doesn't apply to early results. If you ovulated a little late, you may have conceived later in your cycle. In this case, there may not be enough hCG for these tests to detect until closer to or after your missed period. HCG levels should almost double every 48 hours at the beginning of pregnancy. If you are pregnant and you wait a few days to take the test, it is more likely to be positive. Blood tests to detect pregnancy are rarely done routinely because they are expensive and the same results can be obtained from a urine test.
These days you can find out you're expecting much earlier, faster and with better accuracy using home pregnancy tests. Tests labeled for early pregnancy detection may be able to detect a pregnancy several days before your expected period. However, the most accurate results come after your period is late. A certain leading brand in the market claims it will detect pregnancies in 69% of women four days before the missed period.
You question every symptom, wondering if it’s due to pregnancy or premenstrual hormones. And you wonder how soon you can take a pregnancy test so you don’t have to wait any longer for the answer. It does no good for sperm to be hanging around in your reproductive organs unless there’s an egg that’s ready for them.

Many home pregnancy tests claim to be able to tell whether you're pregnant as early as the first day of a missed period. Some claim you can take them even before that point. But home pregnancy test results are more likely to be accurate if they are taken after the first day of a missed period.
If you take a urine pregnancy test at a healthcare provider's office, you will pee into a cup and your provider will dip a test stick into your urine sample. Most home pregnancy tests are 99% accurate when taken the first day of your expected period. Some fertility drugs include hCG to help stimulate ovulation.
If you take a urine pregnancy test too soon, the level of hCG in your body may not yet be high enough to detect . This means you can get a negative result even though you’re pregnant . For the most accurate results, we recommend testing in the morning on the day you expect your period to start. This allows for variability in the timing of ovulation, fertilization, and implantation. Testing in the morning provides a more concentrated urine sample.
To ensure maximum accuracy, take the test first thing in the morning as soon as you wake up when hCG levels will be the most concentrated in your urine.
