possibly pregnant teenager

I'm a 17 year old, and there's a chance that I may be pregnant. As soon as I can, I'm going to take a pregnancy test to find out for sure, but for the time being I'm scared. I don't know what I'll do if it's positive. Abortion and adoption are not options for me, as I have my own personal standings and I wouldn't be able to give up my child. My family would help, I know, but I'm scared. I'm just a kid. Does anyone have advice for me? Anything from what I should do to prepare if it is positive to tips to calm down until I know, to how to tell my family, anything. I don't know if this is the right group, but its worth a shot.
