Chlamydia is sometimes called the "silent" infection as lots of people who have it don't have any obvious symptoms. In fact, 75 per cent of women and 50 per cent of men with Chlamydia have no symptoms at all.
You might develop symptoms if you get Chlamydia, but you may only notice them one to three weeks after you have been infected. Some people only get symptoms many months later or only when the infection spreads.
If you get any of these symptoms after unprotected sex, they may be due to Chlamydia:
- pain when urinating or during sex
- bleeding after sex
- pain in the pelvis or lower abdomen
- in women, heavier periods or irregular bleeding between periods.
