I'm so scared. Not enjoying this.

I'm 5 weeks and 1 day pregnant. It took us 9 months to get a positive but now all I do is worry about it. Every twinge or slight pain that probably isn't even related and I worry that I'm going to miscarry. Please tell me everyone feels this way. I thought I'd be so excited right now but I'm just scared. DH says be calm but I'm always fearing for the worst. This is horrible. :(
