When do you take a pregnancy test?

One of the most exciting, yet sometimes nerve-wracking, moments for women is taking a pregnancy test. Whether you're trying to conceive or not, it's important to know when is the right time to take a pregnancy test, which tests are available, and how to interpret the results. In this blog, we'll cover all the important questions surrounding pregnancy tests, so you know exactly what to expect.

How does a pregnancy test work?

Pregnancy tests work by detecting the hormone human chorionic gonadotropin (hCG) in the urine. This hormone is produced as soon as a fertilized egg implants in the uterine wall, which usually happens about six days after fertilization. As the pregnancy progresses, hCG levels rise, making it easier for a test to confirm the pregnancy.

When is the best time to take a pregnancy test?

The best time to take a pregnancy test depends on your menstrual cycle and the sensitivity of the test you are using. Here are some guidelines:

1. After a missed period: Most pregnancy tests are most reliable if you take them after you have missed your period. At that point, the hCG level in your urine is high enough to be detected by most home tests.
2. Early tests: Some pregnancy tests, especially the more sensitive types, can detect hCG as early as four to six days before your expected period. However, the earlier you test, the greater the chance of a false-negative result, as hCG levels may still be too low to detect.
3. Using first morning urine: It is usually advisable to take the test with your first morning urine, as it is more concentrated and therefore contains a higher concentration of hCG, which increases the chance of an accurate result.

What types of pregnancy tests are available?

There are various types of pregnancy tests available, ranging from standard home tests to more advanced digital versions. Here's an overview of the most common types:

1. Standard urine pregnancy tests
   These are the classic pregnancy tests you can buy at drugstores or pharmacies. You urinate on a test strip or dip the strip in a cup of urine, after which a line or a cross indicates whether you are pregnant or not. Well-known brands include:
• Clearblue: One of the most well-known brands, offering both standard and digital tests. Some Clearblue tests can be used up to 5 days before your missed period.
• Kruidvat Own Brand: An affordable option that provides reliable results.
• Sensitest: These tests are often praised for their sensitivity, allowing you to test slightly earlier.
• Etos: Like the Kruidvat tests, Etos also offers an affordable home test with good accuracy.
2. These standard tests are generally inexpensive, easy to use, and fast, with results within minutes.
3. Digital pregnancy tests
   Digital tests display results in words, such as "Pregnant" or "Not Pregnant," which some women find clearer than interpreting lines. The Clearblue Digital is a popular option. Some digital tests also provide an estimate of how many weeks pregnant you are, based on your hCG level.
4. Early pregnancy tests
   These are designed to detect hCG at a lower level than standard tests, allowing you to test several days before your period. Brands such as First Response Early Result and the Clearblue Early Detection are known for their sensitivity and can be used as early as 6 days before your missed period.
5. Blood tests (by a doctor)
   If you want a more accurate and early confirmation of a pregnancy, you can have a blood test done at the doctor's office. There are two types of blood tests:
• Qualitative blood test: This test simply checks if hCG is present in your blood.
• Quantitative blood test: This test measures the exact amount of hCG in your blood and can provide an indication of how far along you are in your pregnancy.
6. Blood tests are more sensitive than urine tests and can detect a pregnancy within 6 to 8 days after fertilization. However, they are more expensive and the results can take several days.

How reliable are pregnancy tests?

In general, most home tests are very reliable, but reliability depends on when you take the test and how you use it. Here are some factors to keep in mind:

1. Timing: As mentioned earlier, the timing of the test is crucial. If you test too early, the result may be negative, even if you might be pregnant. Most tests have an accuracy of 99% when used on or after the day of your missed period.
2. Correct use: Always read the instructions carefully and follow them precisely. If you use the test incorrectly (for example, by not getting enough urine on the strip or reading the test too early), this can affect accuracy.
3. Test sensitivity: Some tests can detect lower levels of hCG than others. Early pregnancy tests are designed to pick up smaller amounts of hCG, but the chance of a false-negative result is greater if you test too early.
4. Influence of medication: In rare cases, certain medications, such as fertility treatments containing hCG, can affect the result. If you are undergoing treatment for fertility problems, discuss with your doctor when you should best test.

What to do with a positive pregnancy test?

A positive pregnancy test can be a hugely emotional moment, whether or not you were trying to get pregnant. But what now?

1. Confirm the result: Although home tests are very accurate, it is wise to test again a few days after the first test with another home test. In the case of using early pregnancy tests, this is even strongly recommended, given their higher susceptibility to errors.
2. Make an appointment with your midwife or general practitioner: If the pregnancy is confirmed, it's time to make your first prenatal appointment. This usually happens around the eighth week of your pregnancy, but some doctors or midwives may want to see you earlier, especially if you have specific health concerns. So, contact a specialist in good time to seek advice.
3. Start taking prenatal vitamins: If you are not already doing so, it is important to immediately start taking prenatal vitamins, especially folic acid, to support a healthy pregnancy and help prevent birth defects.
4. Live healthy: Stop smoking, avoid alcohol and caffeine, and ensure a healthy diet and regular exercise. It is also important to reduce stress and get enough rest.

What to do with a negative pregnancy test?

If you have a negative test but still think you might be pregnant, it's possible you tested too early or the test didn't work properly. Here are some steps you can take:

1. Wait a few days and test again: Sometimes the hCG level in your body is not yet high enough to be detected, especially if you test early. Wait a few days and try again.
2. Consult your doctor if your period remains absent: If you have had multiple negative tests but your period is still absent, it may be wise to consult your doctor. This could indicate hormonal imbalances or other health problems.

Conclusion

A pregnancy test can be an important first step in confirming a pregnancy, but timing and proper use are crucial for an accurate result. It's best to test after a missed period, and for those who can't wait, early pregnancy tests are available that you can use several days before your expected period. Regardless of the brand or type of test you choose, make sure to follow the instructions carefully to get the best results.

Whether you get a positive or negative result, always seek support and guidance from your doctor or midwife. Pregnancy is an exciting, but sometimes overwhelming, journey, and it's important to get the right care and support from the very beginning.
