Most women with chlamydia have no symptoms at all, which is exactly why this question is so common. Roughly 61% of women with chlamydia never notice anything unusual. That means you can’t rely on how you feel to know whether you’re infected. The only reliable way to know is to get tested.
Still, some women do experience signs worth recognizing, and understanding what to look for (and what happens if chlamydia goes undetected) can help you take action sooner.
Symptoms That Can Show Up
When chlamydia does cause noticeable symptoms, they typically appear one to three weeks after exposure, though some women don’t notice anything for much longer. The most common signs include abnormal vaginal discharge, a burning sensation when you pee, and bleeding between periods. The discharge may have an unusual smell or texture compared to what’s normal for you.
Less commonly, you might feel pain during sex or a dull ache in your lower abdomen or pelvis. These symptoms can overlap with other conditions like yeast infections, bacterial vaginosis, or urinary tract infections, which is another reason testing matters more than guessing based on symptoms alone.
Why Most Infections Go Unnoticed
Chlamydia is often called a “silent” infection. In a large meta-analysis covering more than 26,000 women, about 61% of chlamydia infections produced no symptoms whatsoever. This is not a small minority of cases. It’s the majority.
The infection can live in your cervix and reproductive tract without causing pain, discharge, or any other obvious signal. You can carry it for weeks or months without knowing. You can also pass it to a sexual partner during that time. This is why routine screening matters so much, especially if you’re under 25 or have a new sexual partner.
How Testing Works
Chlamydia testing is simple and painless. The two main options are a vaginal swab or a urine sample. Both detect the genetic material of the bacteria, and results typically come back within a few days.
If you have the choice, a vaginal swab is more accurate. A 2023 meta-analysis found that vaginal swabs detected chlamydia 94% of the time compared to 87% for urine samples. That means urine tests can miss up to 10% of infections that a swab would catch. Many clinics now offer self-collected vaginal swabs, so you don’t necessarily need a full pelvic exam. You can simply swab yourself in a private room.
You can get tested at your primary care provider’s office, a sexual health clinic, or through at-home testing kits that mail your sample to a lab. If you’ve had unprotected sex with a new partner, or a partner has tested positive, getting tested is the straightforward next step regardless of whether you feel fine.
What Happens During a Pelvic Exam
If your provider does a pelvic exam, they’ll look for signs of infection on your cervix. One key indicator is cervical friability, which means the cervix bleeds easily when touched. They may also check for unusual discharge coming from the cervical opening or tenderness when they press on the area. However, these physical signs are unreliable on their own. In studies, cervical friability only identified about 44% of infections. A physical exam alone is not enough to diagnose or rule out chlamydia.
What Untreated Chlamydia Can Do
Left untreated, chlamydia can move from the cervix into the uterus and fallopian tubes. About 10 to 15% of women with untreated chlamydia develop pelvic inflammatory disease, or PID. This is a serious infection of the reproductive organs that can cause chronic pelvic pain, scarring in the fallopian tubes, and difficulty getting pregnant. Some of this damage happens silently, without symptoms that would alert you to a problem, and it can be permanent.
PID is also a major risk factor for ectopic pregnancy, where a fertilized egg implants outside the uterus. This is a medical emergency. The risk of these complications is why routine screening exists: catching chlamydia early and treating it prevents the cascade of damage that can follow.
Treatment and Follow-Up
Chlamydia is fully curable with antibiotics. Treatment typically involves a course of pills taken over seven days. Most people clear the infection completely with no lasting effects, as long as treatment happens before complications develop.
During treatment, you should avoid sex until you and your partner have both finished the full course. Any recent sexual partners need to be tested and treated too, or you risk getting reinfected right away.
The CDC recommends retesting three months after treatment, even if you believe your partner was also treated. Repeat infections are common, not because the antibiotics failed, but because of reexposure from an untreated partner. If you can’t get retested at three months, aim for any point within the following year.
