How Early Can An Early Pregnancy Test Work

What To Do After A Positive Pregnancy Test

How early can I test with a home pregnancy test?

Some women take more than one pregnancy test just to be sure but that’s not necessary. Once you’ve gotten a positive pregnancy test, call your healthcare provider to set up a prenatal visit or to discuss your options if you’re uncertain about continuing the pregnancy.

For prenatal care, providers typically schedule the visit for when you’re at least 8 weeks pregnant, but it varies. Some will see you sooner, particularly if you have a medical condition or have had problems with a pregnancy in the past. It’s especially important to see a provider soon if you’re having nausea and vomiting, vaginal bleeding, or abdominal pain.

If you don’t already have a family doctor, ob-gyn, or midwife, do some research and ask for recommendations. But don’t delay your care while searching for a good fit, because you can always switch providers later. At your first prenatal visit, your provider will take your health history, explain your options, and more.

Pros Of Early Pregnancy Tests

These early detection tests may offer advantages in some circumstances. You may want to discuss your testing plans with your doctor first.

Early Detection

Except for having a physician order an early hCG blood test, which is usually done only when there are medical reasons to detect pregnancy as early as possible, early home pregnancy tests are the fastest way for you to find out whether you are pregnant during a particular menstrual cycle.

The most sensitive tests on the market can potentially give you a positive result four to five days before your period is due, meaning you dont necessarily have to wait for a missed period, or watch for other pregnancy symptoms, to find out whether you are pregnant. However, there is a significant chance of getting a false negative with these tests.

Need to Start or Stop Medications

Very early testing can be helpful if your physician plans for you to start or to discontinue any medications as soon as you discover you are pregnant.

Birth Control Failure

Early pregnancy tests may also be helpful if you were not intending to conceive but had a birth control failure around the middle of your cycle, and you want to know as soon as possible whether you are pregnant so that you can determine your desired course of action.

How Early Can Pregnancy Tests Work

How Early Can Pregnancy Tests Work

Pregnancy tests work by detecting a hormone in the urine called human chorionic gonadotropin . This hormone is produced by the placenta shortly after the embryo implants in the uterine wall.

Most home pregnancy tests are designed to detect hCG levels of 25 mIU/ml or higher. However, some tests may be able to detect lower levels of hCG.

Most doctors recommend waiting until after the first missed period to take a home pregnancy test. However, some women may be able to get accurate results a few days before their missed period.

If you think you may be pregnant, it is best to wait until after your missed period to take a home pregnancy test. This will give you the most accurate result.

How Accurate Are Pregnancy Test Results

Early Pregnancy Tests

At-home pregnancy tests are accurate if you use them correctly. In general, most urine pregnancy tests claim to be 99 percent accurate after a missed period. This depends on how and when you use them.

For example, expired tests may not produce accurate results. You can get optimal accuracy by taking a test after you miss a period and collecting a urine sample in the morning, according to the OWH. Thats because the amount of hCG in your blood increases with time. And finally, some home pregnancy test brands are more sensitive than others.

Understanding Your Options: When Is The Best Time To Take A Pregnancy Test

Sometimes, you may be unsure whether its too early to take a pregnancy test. Other times, you might have symptoms like a late period or breast tenderness but wonder if its worth waiting before making a trip to the drugstore.

There are a few different ways to determine the best time to take a pregnancy test. This is what science has to say about when you should and should not test:

Taking A Pregnancy Test Because Of Symptoms

You may decide to take a pregnancy test because you are having early pregnancy symptoms. But keep in mind, the same hormones that cause pregnancy-like symptoms are present every month between ovulation and your period. Many symptoms similar to pregnancy symptoms can have other causes, like a cold, the flu, or even a few nights of poor sleep.

Other Early Signs And When They Happen

According to the National Institutes of Health , other early signs and symptoms of pregnancy may include:

Some women also report feeling dizzy or wobbly early on in pregnancy, often when they get up after lying down. This symptom may be due to changes in the blood vessels carrying oxygen to the brain.

Some women cannot explain any specific symptoms or changes in their body, but they intuitively feel that something is different.

They might describe it as not feeling like themselves or feeling as though they are suddenly always a step behind. This may be a sign of fatigue and an indication of hormonal changes.

  • You can take a pregnancy test as soon as you miss your period, but it is best to wait until at least one week after a missed period for more accurate results. If you are unsure about when your period is due, take a test 21 days after you had unprotected sex.

    Ideally, you should not take a pregnancy test until the first day of your next scheduled period. Although you can test sooner, testing too soon means you may not have human chorionic gonadotropin in your system for the test to detect, which can lead to a false negative result.

    Since your hCG levels will double every 2-3 days throughout early pregnancy, you will get more accurate results if you wait a few days to take a test.

    If you have a 28-day menstrual cycle, you should wait 29 days after the first day of your previous period or 14 days past ovulation to take a pregnancy test. If you have irregular cycles, try counting back at least 14 days from the last time you had sex.

    The detection limit of many at-home pregnancy tests is approximately 25mlU/ml. Therefore, they may not be able to detect your pregnancy depending on when you check the test.

    In addition, this is a qualitative test, meaning that it only tells you if the value is positive or not.

    A positive test doesnt always mean that the pregnancy is healthy, and a negative test doesnt always mean that you arent pregnant.

    That is why we recommend that you get an office blood test, which is a quantitative test that provides a numeric value for the hormone hCG.

    Hereâs the thing: Because of the way pregnancy is usually measured, youâre not actually pregnant during the first two weeks or so of your pregnancy. Healthcare providers calculate the length of an average pregnancy as 40 weeks, starting from the first day of your last menstrual periodâthis is known as the LMP dating method. So, when youâre 1 week pregnant, youâve only just started your period. At two weeks pregnant, youâre ovulating. And since ovulation happens about 14 days after the start of your period you canât really become pregnant until week 3 at the earliest.It can be mind-bogglingâwe get it. But, for the sake of calculation, and what you and your healthcare provider will consider as 1 and 2 weeks pregnant, youâre not actually pregnant! But although at 1, 2, or 3 weeks pregnant you may not notice any of those very early signs of pregnancy, there may be a lot happening on the inside.

    Hot tub use is one of the things women need to think about if theyre trying to get pregnant. I tell my patients, Take your folic acid and monitor your hot tub use.

    Im not saying you have to eliminate hot tub use completely as I mentioned before, the risk of neural tube defects for a typical pregnancy is 1 in 1,000, and that risk doubles to 2 in 1,000 if you use a hot tub during early pregnancy.

    If you want to totally eliminate the increased risk, avoid the hot tub during the first trimester of pregnancy to give yourself a buffer of a few weeks. A nice, warm bath is a safe alternative if you want to relax in the water.

    If you still want to enjoy the hot tub, soak for short periods of time, make sure the water temperature is below 101 degrees, and avoid the jets where the water is usually the hottest. Once youre past the first trimester, the risk is virtually gone.

    The Best Time Of Day To Take A Pregnancy Test

    The time of day you take a pregnancy test does matter to a certain extent. Youre more likely to get an accurate result if you take the test in the morning. This is especially true if your period is not yet late, or if your period is only a couple days late.

    At-home pregnancy tests work by detecting the hormone human chorionic gonadotropin in your urine. Unless you get up in the night to pee often , your urine is more concentrated when you first wake up. This usually means that the amount of hCG is a bit higher, and youre more likely to get a positive result if youre pregnant.

    However, you can still take a pregnancy test in the middle of the day, or even at night. Youre just more likely to get a false negative, especially if your period isnt that late, and especially if youve been drinking a lot of water and your urine is diluted.

    Blood Test Result Timetable

    Blood tests are able to detect a smaller amount of hCG and they can detect it slightly earlier than standard at-home pregnancy tests, usually nine to 12 days after conception. Blood test results are usually available the same day or within a day.

    Blood tests aren’t often done to detect pregnancy because they are expensive and at-home urine tests are quite accurate and sensitive. However, people who are undergoing fertility treatments may have blood tests as part of their care.
