Chlamydia Symptoms

Chlamydia is a sexually transmitted infection (STI) that is passed from one human being to another through unprotected sex.

The majority of people who may have Chlamydia do not notice any symptoms.

Symptoms may include:

  • Pain whilst urinating
  • Discharge from the vagina, penis or anus
  • Bleeding between periods for women

It is important to get checked if:

  • Engaging in a new sexual relationship
  • After unprotected sex

Chlamydia Symptoms in men and women include:

  • Pain when passing urine
  • Unusual discharge from the penis or vagina
