When is The Earliest You Can Take a Pregnancy Test During IVF?

Before taking a pregnancy test, don’t drink more water than you normally would. Drinking a lot of water can dilute your urine and affect the result of your test. For the most accurate results, take the test first thing in the morning — when your urine is the most concentrated.

Incidentally, hCG is what’s picked up by home pregnancy test strips — but enough of it has to build up in your system first, and your body won’t produce it right at conception. In fact, the fertilized egg has to travel to your uterus first, which can take up to a couple weeks.

Therefore, a blood test can be positive while the urine test is still negative. You should wait to take a pregnancy test until the first day of your missed period. Since HCG is only present once implantation of the egg occurs, there often isn’t enough of the hormone to be detected until you miss your menstrual cycle. While a typical urine test will show positive results at about 20 to 25 mIU, it’s dependent on your urine concentration—the less diluted the urine, the higher the concentration of HCG. Since urine is more concentrated in the morning, a test taken then is more likely to produce a positive result than one taken later in the day. Still, most urine tests will be positive by one to two days after a missed period.

If you take a urine pregnancy test sooner than 10 days after conception, the tests might give a “false negative” result. If you take an early test and it's negative, you should continue to test if you miss a period. It's known as the "pregnancy hormone" because it's produced only when you are pregnant. If you have a 28-day menstrual cycle, you can usually detect hCG in your urine 12 to 15 days after ovulation. 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.

Where To Buy A Pregnancy Test

When it comes to the accuracy of at-home pregnancy tests, research shows if the test is used as directed, an inaccurate result is rare. While false-positive pregnancy test results are uncommon, if you do receive an inaccurate result, it’s more likely to be a false-negative. In this case, it’s likely you’re testing too early, before HCG can be detected. About 85 percent of the time, implantation occurs 6–10 days after ovulation. After implantation, your hCG levels will start doubling every 48 hours — you can use our online hCG calculator to track your hCG levels at home. At this point, pregnancy tests will be able to measure your hCG levels, ensuring a positive result if you’re pregnant.

Spurious evaporation lines may appear on many home pregnancy tests if read after the suggested 3–5 minute window or reaction time, independent of an actual pregnancy. False positives may also appear on tests used past their expiration date. Quantitative tests measure the exact amount of hCG in the sample. Blood tests can detect hCG levels as low as 1 mIU/mL, and typically clinicians will diagnose a positive pregnancy test at 5mIU/mL. A pregnancy blood test can mean a wait of just a few hours or more than a day to receive results.

Human chorionic gonadotropin (hCG)

A test performed several days before an expected period can show a positive result, but the woman still gets her period soon or on time. Rarely, certain tumors can produce hCG, causing a pregnancy test to be positive even when a woman is not pregnant. Thankfully, urine-based pregnancy tests have evolved substantially. Women now have access to advanced tests that can detect a pregnancy as early as eight days after ovulation.

That means you could get positive results several days before you expect your period to start. 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. The best time to take a pregnancy test is the day after your expected period and in the morning hours, with your first urine of the day. However, when you're anxious to see results, it's understandable if you are tempted to test earlier. Getting a negative pregnancy test result doesn't mean your urine doesn't contain the pregnancy hormone .

Ultrasound is also a common tool for determining viability and location of a pregnancy. There is a multilevel urine pregnancy test that measures hCG levels semiquantitatively. This test has utility for determining the success of medication abortion. The beta hCG level is important for checking the growth of the embryo and is highly predictive of live birth.

If you want to know how early you can take a pregnancy test, you might also wonder when the best time to take a pregnancy test is. To get an accurate result, most experts recommend taking a pregnancy test in the morning. While you’re sleeping, hCG becomes more concentrated in your urine. Unless you wake up in the middle of the night to pee, first thing in the morning is the best time for early detection of pregnancy. If your period doesn't begin, repeat the test in a few days or one week — especially if you took the test before or shortly after a missed period.

How Soon Can You Take a Pregnancy Test?

If you take a pregnancy test before you have missed your period, you increase your chances of getting a false negative result. This means the test will read negative when you actually are pregnant, so experts recommend waiting until you have already missed your period to prevent false-negative test results. In general, home pregnancy tests can start to detect the pregnancy hormone hCG around day 21 of a woman’s menstrual cycle. If you tested a week before your period and got a negative result but want to be completely sure, there are a few things you can do. You can re-test at home in a few days or wait to see if you get your period. If the idea of waiting is too hard for you, you can call your doctor or midwife and ask that a blood pregnancy test be done.

Choosing when to take a pregnancy test is an important decision. Whether you’re hoping for a big fat positive or a big fat negative, taking an early test can quickly confirm your hopes or relieve your concerns. Consider setting a timer according to the package instructions. Qualitative tests measure whether hCG is present in your blood or urine.

Different over-the-counter tests have varying levels of hCG they screen for, so you can read the instructions to figure out which one detects the lowest levels. In general, these tests will come back positive if your hCG levels are at least mIU. If you are experiencing early pregnancy symptoms, a missed period or suspect you may be pregnant, use the First Response™ calculator tool. Find out the earliest day you can take a pregnancy test by entering the first day of your last period. You can carry out most pregnancy tests from the first day of a missed period.

If you are pregnant and you wait a few days to take the test, it is more likely to be positive. For the most reliable results, wait until after the first day of your missed period to take a pregnancy test. Small amounts of hCG can sometimes be detected in the urine about 10 days after conception or becoming pregnant. Today, you can find out that you're pregnant much earlier, faster, and with better accuracy using home pregnancy tests.

The study did note that regulations for these tests are different in Europe than in the United States and that the results may also vary based on the user. To use an at-home OTC pregnancy test, you pee on the end of a stick, which will check your urine for hCG. 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.

Always check the test's expiration date and read the instructions carefully before you take the test. Follow the test instructions for how long to wait before checking results — usually two or more minutes. Most tests also have a control indicator — a line or symbol that appears in the result window. If the line or symbol doesn't appear, then the test isn't working properly. During early pregnancy, the HCG concentration increases rapidly — doubling every two to three days.
