Newborn Hearing Screen

My 2 days old newborn baby discharged from hospital with both ear hearing test fail. The test didn’t reach the line bar. Need to come again for another urine test sample for hearing. Did any mummy have the same experience as me? Im worried. I cant even have a peaceful mind & sleep thinking about him. I love him so much, looking at his adorable face.. i hope the next test will pass. My son givebirth normal delivery, 40weeks and 2.75kg.
