First appointment/ultrasound

The day is finally approaching for my first appointment/ultrasound, I’ll be 10 weeks 4 days! I’m feeling pretty anxious about the appointment, the ultrasound especially. I’ve waited 7 long weeks for this day to come and now that I’m 3 days away from it I’m a nervous wreck. I’ve worried since the day I found out about miscarriage and I’m terrified of that being the case. Don’t ask me why but that is my fear. Anyone have any advice?
