First of all, I would get a home pregnancy test and see what that indicates, altho I'm not sure that they are 100% accurate. You say you're going to the doctor soon - why are you waiting? You might not be preg at all, and it could be some other underlying medical problem that might need taken care of.

I wouldn't spazz about it till you know for sure if it's a yes or a no.

If it's a yes, then it's a precious gift that you have been given, and you need to approach how you will deal with it. If you didn't want to get preg in the first place - why didn't you take preventative measures? It's too late to close the door after the horse gets out.....
