Pregnancy test kits have made it convenient to test your pregnancy. Now, you can easily check whether you are pregnant or not by sitting at home. No more doctor visits or clinic visits are required.
The test generally involves line identification. If two lines appear on the slip, it indicates that you are pregnant, and if a single line appears, the test is negative.
However, some people experience changes in the appearance or color of those test lines. Sometimes they seem lighter, and other times they appear darker.
Due to this color change, pregnant women often become worried if the lighter line indicates an issue like miscarriage or other problems.
If you are experiencing the same issue, your pregnancy test line was dark before and has become lighter now. Do you have a fear that something bad will happen to you? Don’t worry, we’re here to assist you!
In this article, we will discuss the changing colors of pregnancy test lines and how dark should a pregnancy test line be at 4 weeks.
how to Properly Take a Pregnancy Test
Nowadays, you can easily take a pregnancy test at home by using a pregnancy test kit. This kit involves a long strip with different features. The procedure for performing a pregnancy test is as follows:
You are supposed to point the absorbent tip of the strip directly at your urine stream for a few seconds so that the device collects an adequate amount of sample to work properly. Alternatively, you can also collect your urine in a sterilized container and dip half of the absorbent pad of the strip in the urine for at least 10 seconds.
Then wait for a few minutes, and you will begin to see two lines on your device window. One line appearing on the right is the control line, which indicates the proper working of the device. The second line on the left indicates your pregnancy.
The color of these lines can vary depending on several factors we will discuss below in this article.

Do Pregnancy Test Lines Become Darker with Time?
Yes, the test lines on your pregnancy test strip should get darker with time. Nevertheless, it’s not always necessary. Generally, the lines on your test strips appear due to the presence of hCG hormone, a pregnancy hormone, and its level increases with time. In early pregnancy, the levels of hCG are low, and hence, if you test your pregnancy during an early period, the line in the strip would appear faint.
With the increase in gestation period, the hcg levels increase in your urine, resulting in dark lines on the pregnancy test strip.
Typically, in the first few weeks of pregnancy, the level of hCG doubles every two or three days. When the pregnancy reaches six-week intervals, the hCG levels will double every 4 days. But after that, as the due date approaches, the lines on the test strip start to fade.
So, if you are testing your pregnancy a day before the date of your expected period, and your pregnancy test line appears lighter, you should not mistake it for a miscarriage. It is just a normal pregnancy procedure.
Why are your Pregnancy lines Becoming Lighter?
There might be several reasons why your pregnancy test lines are appearing fainter than before. The following are some of the primary causes:
Pregnancy test kits made by various brands are available on the market. The sensitivity and the amount of dye can vary in the kits prepared by different brands. If it is more sensitive with a larger amount of dye, the test line will appear darker as compared to the one with a lower sensitivity and dye amount.
The concentration of urine might be a major aspect of the changing colors of pregnancy test lines. If your urine is concentrated, it will have more amounts of hCG hormone, and your test line on the pregnancy strip will appear darker.
Similarly, if your urine is diluted, having more water content and fewer solutes, the hCG level will also be lower, and hence your test line will appear fainter.
It might be possible that one day your urine was concentrated and you had a darker line, but the next day you took more fluid and your urine became diluted, showing a lighter color on the strip.
Should you worry if your Pregnancy line is faint instead of Dark at 4 weeks?
A change in color does not indicate a failure of pregnancy. If you have two lines on your pregnancy device, it means you are pregnant, no matter if it is lighter or darker. It does not link with any miscarriage or serious problems.
Normally, the range of hCG levels should be 10–708 mIU/mL at 4 weeks of pregnancy. However, there are a few things you should keep in mind while performing a pregnancy test, as mentioned above.
You should also check the export date of the kit before using or purchasing it. It might look normal, but it can lead to compromising results.
Conclusion
A pregnancy test is done by pointing the tip of the strip directly at the urine stream. After a few minutes, the lines start appearing on the test strip. If you are pregnant, you will see 2 lines on the strip,
but their color might vary with time. Normally, the color on the strip should get darker with time. However, several factors may contribute to the color change.
If you test a day before your expected date, it will give you a lighter color. The sensitivity and dye amount are also the main factors contributing to the lighter or darker shades of the test line.
It also depends on your fluid intake, as it links directly to the density of your urine. The more concentrated the urine is, the more hCG is present in it, and the darker the line appears. The opposite is the case with diluted urine if you have more fluid.
These, along with other factors, can make you misinterpret it as any miscarriage or other issue, leading you towards anxiety issues. Therefore, there is always a need to see a doctor, specifically during a pregnancy interval.
