2. Vaginal Discharge
For women, abnormal discharge is a key sign of chlamydia. The increase in discharge is caused by your womb being inflamed. If you experience more discharge than usual, a yellowish or greenish discharge, or notice a strong odor, go get tested. A change in discharge can be caused by a number of things. Although healthy discharge can vary from woman to woman, it is usually a sign of infection if it is green or yellow.
