Is it normal to worry that your baby isn't growing?

❤️🌺

I'm 11 weeks and two days today. And I can't help but have that fear that the baby isn't growing. That it stopped after a certain week or something. I see women getting bumps all the time. And I'm not getting that. I had an ultrasound at 9 weeks and the HR was 171. But I still have that fear. Am I in the clear for a healthy pregnancy?
