“How the Body Knows You’re Pregnant | Real Medical Explanation Backed by Science”

Your body can recognize pregnancy within just a few days — long before you even take a test. But how does it know? This video explains the complete biological and medical process behind early pregnancy recognition — backed by real scientific studies and clinical research. We’ll explore how the fertilized egg sends its first signals through the hormone hCG (Human Chorionic Gonadotropin), how the placenta begins forming communication with the uterus, and how the brain, hormones, and immune system work together to confirm and protect new life. All information in this video is based on peer-reviewed medical journals, including research from: The New England Journal of Medicine (2002): Early detection of hCG in maternal blood. Nature Immunology (2004): The role of regulatory T cells in pregnancy tolerance. Endocrine Reviews (2010): Hormonal changes during early gestation.
