First pregnancy

I'm 9 weeks pregnant with my first baby and I'm so nervous. Everyday I read something about missed miscarriages and still borns and it gives me anxiety. I heard my baby's heartbeat for the first time almost two weeks ago & I was told that the chances of a miscarriage decreases once you hear that baby's heartbeat but I've also heard that they can also stop growing ☹️ I NEED to stop reading so much but I'm a nervous wreck and I just really want my baby.
