Chlamydia causes painless discharge or burning while urinating, but it can also cause painful intercourse. In women, symptoms of infection may not appear until weeks later.
Chlamydia is so common that a doctor can test it with just a urine sample.
If left untreated, Chlamydia can lead to pelvic inflammatory disease (PID), ectopic pregnancy, infertility, chronic pelvic pain, and an increased risk of cervical cancer. It is more prevalent in young people, especially teenagers, African Americans, Hispanics, Native Americans, and those living on reservations.
The best way to avoid getting an STD is to use protection when having sex. If you don’t know whether or not your partner has an STI, you should always ask them about it first.
