Early-stage Chlamydia trachomatis infections often cause few or no signs and symptoms. Even when signs and symptoms occur, they're often mild, making them easy to overlook. Signs and symptoms of Chlamydia trachomatis infection can include: 
Painful urination
Vaginal discharge in women
Discharge from the penis in men
Painful sexual intercourse in women
Bleeding between periods and after sex in women
Testicular pain in men
 Chlamydia trachomatis can also infect the rectum, either with no signs or symptoms or with rectal pain, discharge or bleeding. You also can get chlamydial eye infections (conjunctivitis) through contact with infected body fluids.
