Can I test for pregnancy on day 8?

Early pregnancy symptoms usually take more than ten days to appear. If parents are impatient, they will hope to detect whether they are pregnant as early as possible through other methods. Can pregnancy be detected on the 8th day? Let’s take a look at it together below.

Can I test for pregnancy on day 8?

From the meaning of pregnancy, we can understand that it takes 7 to 8 days from the combination of sperm and egg to the middle of pregnancy, and it takes another 7 to 8 days from the beginning of pregnancy to the change of HCG in the female body. At present, the method of checking pregnancy is generally through HCG testing in urine or blood, and early pregnancy test strips are a very commonly used test tool. The main principle of using early pregnancy test strips to measure whether you are pregnant is to measure whether there is HCG in the urine, that is, human chorionic gonadotropin. During pregnancy, women produce specific HCG, which is produced by the embryo. By testing whether it exists, you can determine whether you are pregnant. It usually appears in the urine a few days after pregnancy, but the amount is very small at the beginning and it is not easy to test it out. It will become increasingly obvious after 10 to 14 days. A blood test would be much more accurate.

HCG usually appears in the urine a few days after the embryo implants, and it must reach a certain amount to be detected. Therefore, for women with normal menstruation, HCG can only be detected in the urine after the menstruation is delayed. Women with long menstrual cycles or abnormal ovulation can only be tested after 40-44 days of amenorrhea.

Therefore, it is not possible to accurately detect whether a woman is pregnant at 8 days.

How to use early pregnancy test paper

The main principle of using early pregnancy test strips to measure whether you are pregnant is to measure whether there is HCG in the urine, that is, human chorionic gonadotropin. During pregnancy, women produce specific HCG, which is produced by the embryo. By testing whether it exists, you can determine whether you are pregnant. It usually appears in the urine a few days after pregnancy, but the amount is very small at the beginning and it is not easy to test it out. It will become increasingly obvious after 10 to 14 days.

Before using the early pregnancy test paper, you should use a clean and dry container to collect urine, preferably morning urine; dip one end of the test strip with an arrow mark into the container containing urine, but be careful not to exceed the MAX value of the test paper. Observe the result within 30 seconds to 5 minutes. During the process of observing the results, if only the contrast line appears on the early pregnancy test paper, it means that you are not pregnant. However, if both the contrast line and the test line are colored, but the red and green color of the test line is weaker than the contrast line, it means that you may be pregnant; if both the contrast line and the test line are colored, but the color of the test line is stronger than the contrast line, it means that you have been pregnant for some time.

However, although early pregnancy tests are claimed to be 99% accurate, the reality is that the accuracy of early pregnancy tests varies greatly, ranging from 50% to 75%. The factors that affect the accuracy of early pregnancy test strips are mainly the following:

Performing experiments in the morning and at night may have some impact on the results. The highest HCG value is usually found in the urine in the morning, so many instructions recommend testing it when you wake up in the morning, but this is not certain.

Pregnancy when the man is over 55 years old or the woman is over 35 years old is called an older pregnancy, and monitoring should be increased during pregnancy because the incidence of fetal malformations in older pregnancies is relatively high.
