There's a faint line on my test, does this mean I'm pregnant?

Yes, it means it is an early pregnancy. When you do a pregnancy test too early, the pregnancy hormone (HCG) level is not high, hence the colour is faint. The line will get darker if you do another test later but if it is still faint, it could also mean that the HCG level is hovering at a low level. If the line disappears after, it means that the pregnancy did not take off, which is also known as a biochemical pregnancy. You have to minimally miss your period first before doing a pregnancy test.
