My 5 week old rainbow baby

I go in for an ultrasound at six weeks and three days and I’m just so anxious, unbelievably anxious. I’m just so worried that the baby is not where it supposed to be or the baby is not there in the first place or that I get to see the baby but they stop growing... does anyone have any tips to help me feel less anxious? I know I need to pray more and trust God more I just feel so nervous.
