The uterus begins to contract to shed its inner lining — the endometrium — which had thickened to support a possible pregnancy. These contractions, triggered by hormone-like substances called prostaglandins, cause cramps and pain in the lower abdomen and back. Before and during this time, some women notice white discharge. This discharge, known as leukorrhea, is mostly composed of cervic

Every heartbeat, breath, and movement is powered by microscopic life that keeps us alive. The more we explore, the more we realize how extraordinary the human body truly is."
