pregnant after miscarriage

How do you stay calm? How do you enjoy your pregnancy? 
I'm living in fear that every cramp means I'm losing my baby. That every pain is bad. 
Please help! I know that no blood means no worries but my last pregnancy ended in MMC and my body still went on as I was pregnant until I had my d&c. That was in October of 2015. I just got my positive on Christmas <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">Eve</a> and I have my first appt on Jan 25th. 
How can I pass time and stay calm? 
Thanks ladies.
