How do you keep calm? First pregnancy here

So in the past seven or so months of using Glow I've read so many sad stories of miscarriage at all phases of pregnancy but especially early on. It's got me a little paranoid. I got my first positive test yesterday, and again today with digital at 1-2 weeks estimate. Been seeing a fertility specialist since we had been not preventing pregnancy for the two and a half years prior with no pregnancy resulting, so first blood test tomorrow.

All I can think about is worrying about miscarriage, which won't help my stress levels. I'm 33 and I've never been pregnant before so I have no clue how things are supposed to feel. No symptoms yet, just tested a day before AF was due.

How do you ladies keep calm? Especially during the early weeks when mc is most likely?
