Nervous about first appointment

Hi everyone! This is my first pregnancy after trying with my husband for 2 years! We are so excited and so blessed! I am 6 weeks 2 days. My first appointment is this coming Sunday and I am so nervous! I haven't had many symptoms. I have sore breasts, fatigue, and sometimes back pain. I haven't had any morning sickness. I am worried that when I have my ultrasound, there won't be a baby and only see an empty yolk sac. Any positive thoughts/prayers/words of encouragement would be awesome! Congrats to all you mommies out there! ❤❤❤
