No appt until 12 weeks?!

Km • 27. Married 5 years. Our daughter Stella Claire is our entire world. Born Nov 15. 2015. Pregnant with #2 due in April.
I'm 5w2days with the first. Had my blood test and all but my doc said they don't see me until 12 weeks for my first appt. And we only get to hear the heartbeat-- no ultrasound. That's 7 weeks away. What am I supposed to do before then? Take a test every week until May to be sure I'm still pregnant? I'm worried :(
