Anyone else can't believe they're pregnant?

I'm 9w3d and I still cant believe I'm pregnant. I've had my first doctor's appointment. Only did a urine test and blood labs. And my first US is on March 7th. But I just cant believe its really true! I keep having the urge to do another pregnancy test just to see it be positive. I've miscarried before around 6w4d so I think it might be the fear of that happening again. Anyone with me?
