Pregnancy test 3 days before missed period

When you think you might be unexpectedly pregnant, it can feel like torment waiting to know for sure. You might have sore breasts, mild cramping, and other signs of early pregnancy that could also be premenstrual symptoms, and it causes you to waver back and forth, thinking you are pregnant and then thinking you are not. That can leave you feeling more confused and wondering how soon you can get the answers you need. You have seen ads for pregnancy tests that claim to detect pregnancy five days before your expected period. So, should you test that early? How soon is too early to test for pregnancy? Could you be further along in pregnancy than you think?

When Is It Too Early to Test for Pregnancy?

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.

Why Wait?

As hard as it is, it is best to wait so that if you are pregnant, your body has enough time to produce human chorionic gonadotropin (hCG), the hormone that a pregnancy test will detect in your urine. Your peace of mind in knowing your result is accurate is worth it!

How Do Pregnancy Tests Work?

After sex, an egg is fertilized with sperm (fertilization). The fertilized egg travels to the uterus and attaches into the uterine lining (implantation). Implantation occurs about 7-14 days after you have had sex, and it triggers your body to start producing the pregnancy hormone, hCG. Your hCG levels will double every 48-72 hours after implantation, and it is important to give those levels time to climb.

What About Early Pregnancy Tests?

Early pregnancy test manufacturers market to your desire to get answers as early as possible. It is not hard to see the advertising on the box and read the claims of 99% accuracy along with the ability to detect pregnancy six days before your missed period.

But let us take a closer look, so you do not test too early for pregnancy. The first thing to consider is that the percentage provided on the front of the package is only accurate when you take the test on the day of your expected period — and in a laboratory setting by professionals. The same goes for the the instructions printed inside the pregnancy test kit; the claims of accuracy are elevated because they do not reflect real-life testing in real-life situations.  The results from a University of New Mexico study reveal the chances you can anticipate getting the right answer from an early home pregnancy test:

• One day past your expected period: 100% of pregnancies detected

• On the day of your expected period: 96% of pregnancies detected

• On the day before your expected period: 93% of pregnancies detected

• Two days before your expected period: 81% of pregnancies detected

• Three days before your expected period: 68% of pregnancies detected

• Four days before your expected period: 42% of pregnancies detected

• Five days before your expected period: 33% of pregnancies detected

• Six days before your expected period: 25% of pregnancies detected

When Is the Best Time in Your Cycle to Test?

Although your body begins to produce hCG 7 to 10 days after fertilization, waiting provides the most accurate results. In order to give your body enough time for hCG to build up to a detectable level in your urine by a pregnancy test, it is best to take a pregnancy test about 14 days after fertilization. For a woman who has a 28-day cycle and ovulates 14 days after her last period, this would mean testing on the day you expect your next period if you suspect you are pregnant. For the most accurate results, take a pregnancy test a couple of days after your missed period.

If your test is negative and your period does not start, you still might be pregnant, but your hCG levels are just not high enough to register on the test. Most testing kit instructions recommend you wait one week to take another test; however, many women test a few days later. Contact a healthcare professional if you still have a negative pregnancy test or have further questions.

When Is the Best Time of Day to Take a Pregnancy Test?

The best time of day to take a pregnancy test is first thing in the morning because at that time your urine  contains the highest concentration of hCG. This is particularly important the earlier you are taking your pregnancy test. You can test later in the day, but you will have a higher chance of seeing a false-negative test result because your urine will be diluted. Tips for testing include:

• Use first-morning urine (or after you haven’t urinated in at least four hours).

• Don’t drink a lot of fluid that could dilute your hCG levels before your test.

• Check to make sure the pregnancy test is not expired, which can provide inaccurate results. Checking the expiration date is particularly important if you keep pregnancy tests at home “just in case.”

• It is understandable that once you have the pregnancy test in your hands, you want to get to the answers quickly. Plus, it seems like a no-brainer because they are designed to be easy to use. Take time to read all of the instructions and follow them precisely. Even if you have taken pregnancy tests before, little variances between them can be the difference between a result you can count on and a wrong one.

• We all know how easy it is to lose track of time, so do not try to estimate when to read your results. Set a timer so you can read your test results exactly at the time directed in the instructions. Do not read the test window after that set time because a faint “evaporation line” can appear, which makes your test appear to be positive when it is really negative.

Hopefully, this information is helpful to understand the value of not testing too early for pregnancy, so you can have peace of mind knowing your results are accurate.
