Pregnancy is a sustained physiological transformation — the body reorganizing itself around the demands of growing another human — and it asks more of cardiovascular, nutritional, immune, and musculoskeletal systems than any other normal life experience. Good prenatal care combines evidence-based monitoring for risk with genuine support for the pregnant person's wellbeing, not just the pregnancy. Both modern obstetrics and traditional midwifery wisdom have important contributions to make here, and the best care draws from both.
Each step builds on the last.
