1st ultra sound

I had my first ultra sound done today! It was beautiful. But she set me back to 6 weeks 1 day from my last period it says 7 weeks. My levels were at 6,000 Tuesday last week when I had blood work done. Estimated due date is Jan 2nd or Jan 8th. I'm ready to get out of the first trimester so I can stop worry about everything I'm ready to start showing and find out what this sweet baby is! Heart rate is at 129! I'm hoping for a girl really bad so soon we will know.
