Pregnancy hormone

Pregnancy hormones are chemicals produced by your body to support pregnancy. The main hormone, human chorionic gonadotropin (hCG), is made after fertilization and helps maintain the pregnancy by encouraging the ovaries to produce important hormones. Another key hormone, progesterone, thickens the uterus lining and prevents contractions, creating a safe environment for the developing baby. Estrogen, also elevated during pregnancy, supports tissue growth and blood flow. Together, these hormones regulate pregnancy changes, help develop the fetus, and prepare the body for childbirth. Their levels are often monitored during pregnancy to ensure healthy progression.
