9 weeks and getting anxious

Kaisha
My first prenatal appointment is Monday. It's not an ultrasound just bloodwork and an exam. Glow and planned parenthood put me at 9 weeks. I'm so worried that I won't see a heartbeat. I'll be 10 weeks or so by my first ultrasound. What is the likelihood of miscarrying at this far along? I know I'm far from being in the clear.
