Well sometimes the test results are inaccurate if it's too early to tell, and please ignore the comment about abort. There are other options.

Go to the doctor. If you're pregnant, they'll be able to tell you that. If you're not, you need to be examined to see why all this stuff is going on. You only have one body, take care of it. Don't wait.

seriously, see wut is wrong. you need to know if your pregnet ahead of time. a baby is a lot of work. if you can't take care of a baby, you might have to abort... that is definetly wut I'd do if I got pregnet, but then again I'm 14 and haven't even, you know, but it is a very big thing that you really should put off.
