Momsh, yung hemoglobin mo talaga ay mababa para sa CS kaya may sense ang doctor mo, a few of us din nag-transfuse before surgery dahil same concern, at honestly it made us feel mas secure na. Best to follow your OB's advice on this one since it's about your safety during the operation, pero if may specific worries ka about the transfusion process mismo, okay lang mag-ask directly sa hospital kung ano ang exact procedure and what to expect, para less anxious ka on the day!
