5 weeks tomorrow!

Km • 27. Married 5 years. Our daughter Stella Claire is our entire world. Born Nov 15. 2015. Pregnant with #2 due in April.
Had my blood confirmation tonight, should know tomorrow -- although I can't see how I'm not preggo. My boobs are throbbing, I'm always hungry and I have weird aches and pains in my uterus. A week later officially. 
What should I know from here? I'm guessing I won't see my doc until 8 weeks for my first appt. Anything I should do until then?
