4 weeks 5 days pregnant

Just found out I’m pregnant, I took an hcg on 11/22 it was 560.3. However, when I went in for my ultrasound with my hcg levels being at 560 they clinic couldn’t see anything on the ultrasound which is normal because it could just be super early, but I’m also worried because I don’t have any symptoms really no bloating just sore boobs…should I be worried…
