Clear discharge before period is usually normal and often reflects hormonal changes during the menstrual cycle. Discharge may appear clear, slippery, watery, or stretchy depending on hormone levels and ovulation timing. However, discharge accompanied by a strong odor, itching, burning, may indicate an infection or another concern. USA Fibroid Centers encourages women to understand changes in their reproductive health and consult a healthcare professional if discharge becomes unusual or persistent.
