Understanding Your hCG Levels and Doubling Time

The Importance of hCG in Early Pregnancy

Human chorionic gonadotropin (hCG) is known as the pregnancy hormone. In a typical healthy pregnancy, hCG levels usually double every 48 to 72 hours during the first few weeks. Knowing this doubling time can give you and your doctor an early indication of how your pregnancy is developing.
