It’s one of the most common STIs in Britain and you can get it through unprotected vaginal sex, anal sex or oral sex as well as close genital contact. About one in 14 people aged between 15 and 24 will get Chlamydia at some point


Most people won’t have any symptoms at all if they have Chlamydia so it’s important to get checked out if you have unprotected sex. If you do have symptoms, they may include the following:


  • unusual vaginal discharge
  • pain when weeing
  • heavy period or bleeding between periods
  • pelvic and lower abdominal pain
  • abdominal pain during vaginal sex and/or bleeding during or after sex.

If left untreated, Chlamydia can do serious damage to a woman’s fallopian tubes sometimes resulting in ectopic pregnancy . This is when the baby starts to grow outside of a woman’s womb putting both mum and the unborn baby’s lives in danger. She can then become infertile.



  • discharge from penis
  • pain when weeing
  • painful swelling of testicles.

If left untreated in males, Chlamydia can lead to Reiters Syndrome (which is a form of Arthritis) and infertility.



The test for Chlamydia isn’t embarrassing or painful: it’s usually a simple swab or urine test.

It’s easy to treat. A course of antibiotics will clear it up in a few weeks. Get tested at your GP surgery, a family planning clinic, a sexual health clinic or via EYPDAS.
