Worried waiting for next scan

I had my first scan we I have 5w4d and it was to early to see a heartbeat and now my next scan isn’t until may 3rd when I will be around 12w I know 6 weeks isn’t a long time but I keep seeing all these posted about missed miscarriage ect and it’s making me nervous also because now at 9w all my symptoms have died down.

Is this normal first time pregnancy worries or do I need to chill the fuck out?
