Pregnancy Anxiety

When they say pregnancy anxiety is real, they weren't joking. FTM and had my 1st US at 5w4d for placement. They saw only the gestational and yolk sac in the uterus, advised to repeat 2 weeks (7weeks) for viability. I've read that some already saw fetal poles / cardiac activity at 5w and I'm kind of panicking. Is that normal? My symptoms have also decreased but I read it's quite normal for it to come and go. Testing every other day as well and lines are still dark. Need assurance and prayers please ✨🥹
