Positive from the doctor

Kia-Shun
After a false positive last December we got a positive from the doctor today. I'm excited for my first child. although I'm only 4w+3 its a long way to the finish line. 
What do other moms do to keep sane about the possibility of a miscarriage.
Next doctor appointment isn't until July 20th. That's a long way away!!! Yikes
