Questioning whether or not you are pregnant can be a nightmare, especially if you are trying to conceive. When you take a pregnancy test at home, and see that positive line, you feel a sense of cautious happiness, which can tempt you to test again and again. If you see the positive line fading, you may panic and wonder, why is my pregnancy test getting lighter?

It's important to know how a pregnancy test works in the first place. According to Dr. Eva Martin, CEO of Elm Tree Medical, Inc., pregnancy tests detect the hormone human chorionic gonadotropin (hCG), which is produced after your fertilized egg implants itself into your uterus. Martin tells Romper that the hormone is released into your blood and urine, and the positive lines on the pregnancy test show up only when hCG is present.

So what does it mean if the lines are darker or lighter? Very Well explained that the positive lines on a pregnancy test can get lighter or darker depending on the concentration of hCG in your urine, which can fluctuate according to how much fluid you drink, how much you urinate, and what time of day you test. So if you drink a lot of water, or test towards the end of the day, the line may be lighter.

Does a lighter line indicate a change in your pregnancy? According to the American Pregnancy Association (APA), a positive line on a home pregnancy test indicates the presence of hCG in your system, which still means you are pregnant, no matter how faint the line gets.

If you are worried about your pregnancy, it's best not to drive yourself crazy with taking repeated at-home tests. If you do see a positive line, and think you are pregnant, it's best to call your doctor and make an appointment. Doctors can provide you with blood tests and ultrasounds, and give you more accurate results and analysis. In the meantime, enjoy the positive lines, and the positive vibes that are coming your way.
