Nervous

I had a positive test on the 4th of July. What a great holiday! Today should have been the first day of my period. I feel like knowing this early is so scary! My first ob appointment isn't until the 19th, almost 2 weeks away Sad I'm worried about everything. Everything I eat, everytime I move and get a little cramp. I read about ligament pain, and I try to tell myself that is all I am suffering from, but this early on how can I be sure? I have been so tired lately and working nights doesn't help at all. My fiance' is being very very supportive, though. We always said we were afraid to get pregnant, now we are afraid something will happen to the baby. We are so excited! Well, just a quick update...need to fit a nap in before work.
