Talk to Pediatrician on 11 Day Old Baby Spits/vomits Milk Curd + Milk After Half An Hour To An Hour

Aoa, my 11 day old beloved daughter, is vomiting or spitting milk after half an hour to an hour. she does that even after burping, sometimes I feel she feels pain in stomach as she curl her legs toward stomach and tighten the gut muscles. She only cries when burping and seems comfortable pre and post vomit.

we aren't administering any med yet,

a quick suggestions might help until we see a reputable doctor in person.
