Am I the only one?

I can't stop thinking about losing my baby. I'm really weeks 5 days today and I found out about a week ago I was pregnant. I've had a healthy pregnacy before my daughter is 2 now. Is it normal to always think about what if I go in for my first ultrasound and there's no heart beat, baby, or if I start bleeding. I just can't seem to stop worrying.
