need prayers.

I'm getting seriously tired of being sick all day. I have this insane craving for something and I have no idea what it is. Everything I tried to eat today has come right back up and I was just reduced to crying on my bathroom floor. I need to know if I am pregnant or not. I tried calling my ob-gyn today to make an appointment but NO ANSWER! I swear if I get my period next week I am going to go off-the-wall crazy. 
I can handle the sickness and exhaustion and all of the difficult things that come with pregnancy, but I need to know that I am in fact pregnant!!!!!! If I'm doing this for my baby then I'll walk through hell and back. My doctor needs to answer their phone. ugh. Somebody pray for me!
