☹️baby spits up after every feeding

My son is 5 days old and spits up after every feeding he has. We have tried formula (3 different types now) as well as my breast milk that came in today and so far nothing has changed. We’ve been to the pediatrician we had a metabolic panel done because he has jaundice and they checked to see if he was dehydrated which thankfully he isn’t.

Is there anything I can do? I feel so bad when my baby gets sick after every feeding...
