Has anyone gone through this ?

My baby is 6 days old and was born with jaundice and for her first check up her level increased slightly and it’s giving me bad anxiety 🥺 the nurse said it didn’t increase significantly so they weren’t worried but I can’t seem to shake the feeling that somethings wrong … the ftm anxiety is killing me 😭 has this ever happened to anyone and it turned out ok ? Baby has another check up saturday to check levels again
