What does it mean if there is a faint blue line on a pregnancy test???

Question

So, I've been off my birthcontrol for a little over a month, and I haven't had my period. So I decided why not, I'll take a test. Well I took the test and right where the arrow is a blue like showed up. and I was like holy crap!!! Well I went to take a photo to send to my best friend and it was just gone. So I'm not entire sure what's going on, I've never had to do this before so I need some advice.. ;-;
