Anyone else worried or is it just me?

I’m pregnant with my rainbow baby. The one and only symptom that’s been able to comfort me and let me know my baby is still growing and thriving was puking. This now starting to go away but is scaring me and kept questioning myself if the baby is still ok, if it still has a beating heart? I’m getting so worried that my baby disappeared! And I know that it’s there and I’m sure it’s doing fine but the anxiety is getting bad! Anyone else dealing with this? Any tips to try and not worry?
