Getting a faint line on a pregnancy test can be frustrating—and confusing. Pregnancy tests detect the hormone human chorionic gonadotropin (hCG). Because of this, even a faint line usually means you’re pregnant. It could be that you’re early on in your pregnancy and hCG levels are low, which can lead to that faint line. It might also be the case that the test you used isn’t particularly sensitive. In some cases, it may be that you’ve experienced an early pregnancy loss. (The only way to have more insight is to test yourself again again in a few days and see if the line gets darker or lighter.) There’s also the chance that you’re looking at an evaporation line, which can happen if you check your test results after the recommended time interval. That line could be the ink getting caught in the urine line and appearing after the urine dries.
