Successful pregnancy stories?

I need successful pregnancy stories! :( I had a chemical pregnancy in January and now I’m currently 9.3 weeks pregnant , and had a ultrasound 3 days ago and saw heartbeat (174 BPM) and I hear chances of miscarriage is lower after you’ve seen/heard a heartbeat , but it seems on here, the chance is soooo high! On google the percentage looks so low at this point, but almost everything I read here seems like everyone has had one! I’m already a worry wart and need encouragement :/ I already hardly have pregnancy symptoms. I knowww I’m not in control and need to stop worrying so much
