11 weeks pregnant question

So I saw the heart beating at 5 weeks 4 days, 7 weeks 6 days, and I heard the heart for the first time at 10 weeks 6 days. My next appointment for nuchal translucency is in 3 days.

Of course I’m still worried there won’t be a heartbeat. But I feel like once this ultrasound is completed I will feel slightly more at peace since it’ll be just about 12 weeks.

Since I’ve seen/heard the heart 3 times already would say that the chance of miscarrying is extremely slim?

Need some reassurance after my first missed miscarriage :(
