When infected with Chlamydia, it is rare for your body to show symptoms (it is usually asymptomatic)
Some symptoms you might show are:
pain in eyes, lower abdomen, pelvis, testicle, and vagina
pain during sexual intercourse or during urination
abnormal vaginal discharge, discharge from penis, sporadic vaginal bleeding or swollen or tender testicles
Because chlamydia is usually asymptomatic, most people infected are unaware that they have it. This is why chlamydia is so common.
