Is it true?!

Is it true that once you see/hear a heartbeat your risks of miscarrying go down? I miscarried a few months ago and found out that I am currently 7 weeks. We went for a ultrasound at 6 weeks 2 days and we saw a strong heart beat of 130bpm. I feel like all I can think about is miscarrying and praying that it doesn't happen.
