thinking about things

Ok here's the thing,  I looked at the signs and symptoms of pregnancy earlier today and aside from 1 symptom I have nearly all of them. I don't know what to do. I have had scares before and everytime it ends up false and I feel so stupid, so what do I do? I don't want to get to the doctors and have them tell me…..again that I am not. We are not actually trying either so I am really wondering what to do. *Confused*
