Chlamydia Symptoms in Women: Testing, Treatment and Risks
Most women with chlamydia have no symptoms. When symptoms do show up, they can include unusual vaginal discharge, burning when you pee, bleeding between periods or after sex, and pain in the lower belly or during sex. It's diagnosed with a urine test or vaginal swab and cured with antibiotics. Left untreated, it can damage the fallopian tubes and affect future fertility.
According to the CDC, chlamydia is the most commonly reported bacterial STI in the United States, and it's especially common in people under 25. So the honest answer to "do I have symptoms?" is that it often doesn't matter. Testing is how you know.
The symptoms, if you get any
When women do notice something, it may be:
- Discharge that's different from usual, sometimes yellowish
- Burning or pain when you pee
- Bleeding between periods
- Bleeding or pain during or after sex
- Lower belly or pelvic pain
- Rectal pain, discharge or bleeding, if the rectum is infected
- Rarely, a sore throat after oral sex (throat infections usually cause no symptoms)
A lot of people assume burning means a UTI and drink cranberry juice for a week. These symptoms overlap with UTIs, yeast infections and bacterial vaginosis, and you can't tell them apart by feel. Our guide to vaginal discharge covers the common patterns.
How long until symptoms show up?
If symptoms develop at all, they often appear within a few weeks of exposure. Many people never get any, so feeling fine doesn't rule it out.
How it spreads (and how it doesn't)
Chlamydia spreads through vaginal, anal or oral sex with someone who has it. It spreads even when the partner has no symptoms and even without ejaculation. It can also pass to a baby during vaginal birth.
You can't get it from toilet seats, shared towels, kissing or swimming pools. Everyone wonders. Now you know.
Who should be tested, and how often
The CDC and USPSTF recommend screening for:
| Who | How often |
|---|---|
| Sexually active women under 25 | Every year |
| Women 25 and older with a new partner, more than one partner, or a partner who has other partners or an STI | Every year, or as recommended |
| Pregnant people under 25, or older with risk factors | At the first prenatal visit, and again later in pregnancy if risk continues |
| Anyone with symptoms or a partner with chlamydia | Right away |
| Anyone treated for chlamydia | About 3 months after treatment |
If you're under 25 and haven't been tested since last year's checkup, just ask at your next visit. You can say, "Can you add chlamydia and gonorrhea?" and nobody will blink.
What the test is actually like
Testing is quick and usually painless:
- Vaginal swab: often self-collected in the bathroom. You insert a long cotton swab an inch or two, rotate it for about 10 to 30 seconds, and drop it in a tube. The CDC considers this the preferred sample for women.
- Urine sample: also accurate. Many clinics ask that you not pee for an hour or two beforehand.
- Throat or rectal swabs: needed if you've had oral or anal sex, because a vaginal or urine test won't pick up infection there. Mention it, even if it feels awkward. It changes what gets tested.
Most chlamydia tests are run together with gonorrhea. Results often come back within a few days.
Where to get tested in New York
- NYC Health Department Sexual Health Clinics see anyone 12 and older at low or no cost. See STI testing in NYC for details.
- Gynecology and primary care offices, including through your annual exam.
- Teens: New York minors can consent to their own STI testing and treatment.
You tested positive. Here's the next week.
Chlamydia is curable. The CDC's preferred treatment for most adults is a 7-day course of an oral antibiotic, with other options for pregnancy or when that medicine isn't a fit. Your clinician will choose.
What to do from here:
- Take every dose, even after you feel fine.
- No sex until you and your partner(s) have finished treatment and at least 7 days have passed. Your clinician will give you the exact timing.
- Tell your partner(s). Untreated partners are the most common reason people get it again.
- Get retested about 3 months later, because reinfection is common.
- If you're pregnant, you'll usually be retested about 4 weeks after treatment to confirm it's gone.
Expedited partner therapy in New York
New York allows expedited partner therapy (EPT) for chlamydia. Your clinician may give you medication, or a prescription, to pass to your partner(s) so they can be treated without their own exam first. It takes a lot of the awkwardness out of the "you need to get treated" conversation. Ask whether it's an option, and encourage partners to still get tested for other STIs.
What happens if it isn't treated?
Untreated chlamydia can spread from the cervix to the uterus and fallopian tubes and cause pelvic inflammatory disease (PID). PID can lead to:
- Long-term pelvic pain
- Scarring of the fallopian tubes
- Ectopic pregnancy, a pregnancy outside the uterus that can be life-threatening
- Infertility
Chlamydia can also raise the risk of getting HIV. In pregnancy, it's linked to complications and can pass to the baby at birth, causing eye infections or pneumonia. Prompt treatment greatly lowers all of these risks.
Can you get it more than once?
Yes. Treatment cures the current infection but doesn't make you immune. Reinfection is common, usually because a partner wasn't treated or a new partner has it. That's why the CDC recommends retesting about three months after treatment, even if you and your partner were both treated. Repeat infections raise the risk of PID and tubal damage, so keep up regular testing.
Chlamydia vs. gonorrhea vs. trichomoniasis
| Chlamydia | Gonorrhea | Trichomoniasis | |
|---|---|---|---|
| Caused by | Bacteria | Bacteria | Parasite |
| Symptoms in women | Often none | Often none | Sometimes frothy, yellow-green discharge, itching, odor |
| Test | Swab or urine | Swab or urine | Swab or urine |
| Treatment | Oral antibiotic | Antibiotic injection | Oral antibiotic |
| Risk if untreated | PID, infertility | PID, infertility | Higher HIV risk, pregnancy complications |
Prevention that works
- Use condoms correctly every time for vaginal, anal or oral sex
- Get tested regularly, especially with new partners
- Talk about testing with partners before sex
- Wait until partners are treated before having sex again after a positive test
- Fewer partners means less exposure
There's no vaccine for chlamydia.
When to see a doctor
See a gynecologist, women's health nurse practitioner, or sexual health clinic if:
- You have any of the symptoms above
- A partner tells you they have chlamydia or another STI
- You're under 25, sexually active, and haven't been tested this year
- You have a new partner or multiple partners
- You're pregnant or planning a pregnancy
Get urgent care for severe pelvic or belly pain, fever, nausea and vomiting, or pain with a missed period. Those can signal PID or an ectopic pregnancy.
Find a gynecologist or women's health nurse practitioner near you, or search the directory by borough or county.
Frequently asked questions
What are the first signs of chlamydia in a woman?
Most women have no symptoms at all. When symptoms happen, they can include unusual discharge, burning when you pee, bleeding between periods or after sex, and pelvic pain.
Can chlamydia go away on its own?
Don't count on it. Untreated chlamydia can last for months and spread to the uterus and fallopian tubes. It's easily cured with antibiotics, so testing and treatment are the safe choice.
How soon after sex should I get tested for chlamydia?
Testing too soon can miss an infection. Many clinicians suggest waiting about one to two weeks after an exposure, but get seen right away if you have symptoms or a partner has tested positive.
