Is "positive" necessarily positive?

After 3 days late and a lot of worry, I took a HPT this evening. You guessed it - positive. So was the second one. But this pregnancy is from a casual hookup and circumstances aren't good. I am so overwhelmed I don't know what to do. And I can't even call the gyno until Monday to talk about options and get a better grasp on things. Please tell me I'm not the only one going through this. *Sigh*
