A sexually transmitted infection (STI) is a bacterial or viral infection that is passed on during unprotected sexual contact – this also includes oral sex.
If you haven’t used a condom or it has split it is really important to get tested so you don’t pass an STI on to someone else or cause yourself any harm.

Signs and symptoms
Whilst some STIs have symptoms many don’t, so instead of hoping that you don’t have one it’s best to get checked.

Some STI symptoms include:
- Unusual discharge

- Soreness or swelling of the vagina
- Pain, burning or increase in your weeing
- Irregular bleeding
