20 weeks scan

I have my “20” week scan on Tuesday which I’ll be 23 weeks but I’m SO nervous. I haven’t had an ultrasound since 6 weeks. Mostly because I’ve had issues with my insurance and the ultrasound but I haven’t seen his little face yet! Just blood work and regular appointments. I think naturally in scared something will be wrong! Any other moms felt this way? How did you ease your mind and anxiety before leading up to the appointment?
