How will I know if I have an STI?

Think about the following questions:
  • Are you sexually active?
  • Have you had more than one sexual partner?
  • Has your partner had more than one sexual partner?

If you've answered ‘yes’ to any of these questions then you're at risk of an STI and should be tested.

STI symptoms

Although many people will have no symptoms, you should definitely be tested if you have:

  • Unusual genital/anal discharge
  • Genital sores, growths or lumps
  • Pain when passing urine
  • Painful sex or bleeding after sex
  • Pain in the lower abdomen
  • Genital pain

For women, an indication of an STI can be bleeding in between periods. The symptoms of an STI may come and go; this doesn't mean the infection has gone. It's still important to be tested as having one STI can make you more vulnerable to getting others.

The risks of not being tested and treated for STIs can vary from pelvic pain, ectopic pregnancy, infertility in both men and women, and – in extremely rare cases – chronic debilitating secondary infections.
