• Stress or emotional upheaval
• Polycystic Ovary Syndrome (PCOS)
• Thyroid dysfunction
• Changes in exercise or weight
• Pregnancy (even when home urine tests are negative or unclear)

Science Spotlight: The Role of hCG in Early Pregnancy Detection

hCG (human chorionic gonadotropin) is only produced after conception, and builds up quickly in your blood. Importantly, blood tests can detect hCG sooner than urine tests and can provide an exact number — helping diagnose very early pregnancies or rule out pregnancy as a cause of your symptoms.
