Explanation
If you have had unprotected sex and there is a chance that you may have got chlamydia, you should make an appointment to have a test as soon as possible.

Explanation
If you have chlamydia and don't get treatment, you could pass the infection onto a sexual partner. Using condoms isn't a substitute for getting treatment. Using a condom will reduce your risk of passing on the infection, but it won't offer complete protection.
Chlamydia can cause health and fertility problems if it's left untreated.
For example, in women, untreated chlamydia can cause pelvic inflammatory disease (PID) which may increase your risk of infertility and complications during pregnancy.
In men, it can infect the urethra (the tube from the bladder to the tip of the penis) or the prostate gland (which makes the liquid part of semen) and may affect fertility. Untreated chlamydia can also cause a type of arthritis called sexually acquired reactive arthritis in some men and women. Please see the Complications section in the Chlamydia health factsheet for more information.
