First maternity appt nerves

Y'all, I'm nervous. I'm 8w4d & tomorrow is my first prenatal appt. I believe I'll get to hear the heartbeat and ultrasound but I'm so nervous. What if something is wrong? What if they make me wait another week or two for ultrasound. I'm just ready to see my baby to make sure everything is fine so I can begin enjoying being pregnant. Any advice? What should I expect?

Xoxo,
