STD Symptoms in Women: Signs, When to Test and Where in Los Angeles

This page is general health information, not medical advice. It cannot tell you whether you have an infection. A clinician can, and the testing options on this site are a good place to start.

Many sexually transmitted infections cause no symptoms at all. Others cause signs so mild they are easy to mistake for something ordinary. That is why a list of symptoms is only half the story, and why an STD test for women is the only way to learn what is going on.

This guide covers the symptoms of an STD in a female body, the signs that deserve a call to a clinician, how testing works, and where to get tested in Los Angeles. It is written for women, and for anyone with a vagina, cervix or uterus, whatever their gender or orientation.

Key takeaways

  • Chlamydia, gonorrhea, trichomoniasis, herpes, HPV, syphilis and HIV can all be present without any noticeable sign, according to the CDC.
  • Symptoms, when they happen, often look like a yeast infection or a urinary tract infection. Only a test and a clinician can sort out the cause.
  • The CDC's 2021 STI Treatment Guidelines recommend yearly chlamydia and gonorrhea screening for sexually active women under 25, and for older women with risk factors such as a new partner or a partner with an STI.
  • Untreated chlamydia and gonorrhea can lead to pelvic inflammatory disease, which can affect fertility. Early testing and treatment lower that chance.
  • Severe pelvic pain, fever, or symptoms during pregnancy are reasons to be seen the same day.
  • In Los Angeles, the County Department of Public Health runs sexual health clinics that are free of patient charges, and several community clinics offer testing too.

Why most STIs cause no symptoms

Silence is the most common thing an STI does. The CDC's STI Treatment Guidelines (2021) note that most women with chlamydia have no symptoms, and the same is true of many women with gonorrhea and trichomoniasis. Herpes and HPV often pass without anyone noticing a sign. Early syphilis and HIV can be quiet, too.

This is not a personal failing or a sign of anything about your life. Infections in the cervix, throat or rectum often have no nerve endings that register discomfort. Symptoms that do appear can be mild, come and go, or look like other common conditions.

It also means a person can pass an infection on, or develop complications, without ever feeling ill. That is the main reason screening exists. Screening means testing when you feel fine, on a regular schedule that fits your life.

Why symptoms are easy to misread

Vaginal itching, discharge and burning with urination have many possible causes. These include yeast infections, bacterial vaginosis, urinary tract infections, irritation from soaps or fabrics, and hormone changes. Some of these are not sexually transmitted.

You cannot reliably tell the cause by how it looks or feels, and neither can a guess based on a partner's history. A clinician can examine you, collect a sample and test for the right things.

Local context

Los Angeles is a large city, and STIs are common here. The Los Angeles County Department of Public Health reports a 2024 chlamydia rate of 493 per 100,000 people (45,459 cases) and a gonorrhea rate of 252 per 100,000 (23,272 cases) in the county, excluding Long Beach and Pasadena. These figures are provisional. They describe how often infections are found, not who is at fault. They are a reminder that testing is a routine part of health care here.

Symptoms of an STD in women, infection by infection

The table below summarizes signs the CDC describes for common STIs. Having one of these signs does not mean you have a particular infection, and having none does not mean you are free of one. Only testing can say.

InfectionSigns that can appearOften silent?
ChlamydiaUnusual vaginal discharge, burning when urinating, bleeding between periods or after sex, lower abdominal pain, pain during sexYes, most often
GonorrheaIncreased or changed discharge, burning when urinating, bleeding between periods, pelvic painYes, often
TrichomoniasisFrothy or yellow-green discharge, odor, itching, irritation, discomfort when urinatingYes, often
Genital herpesPainful blisters or sores, tingling, itching, flu-like feelings with a first outbreakYes, often very mild
HPVGenital warts, or no signs at all; cervical changes are found on screeningYes, usually
SyphilisA firm, usually painless sore; later a rash, often on palms and solesYes, the sore can go unseen
HIVFever, sore throat, rash, swollen glands in the first weeks for some peopleYes, for years without testing

Chlamydia and gonorrhea

These bacterial infections often cause no signs. When they do, the CDC lists changes in discharge, a burning feeling when urinating, bleeding between periods or after sex, and pain in the lower belly or during sex. Both can also infect the throat or rectum, depending on the kind of sex a person has, and those sites often cause no symptoms either.

Both are curable with treatment from a clinician. That is one of the strongest reasons to test: a result gives you a clear path forward.

Trichomoniasis

Trichomoniasis is caused by a parasite. The CDC says many people with it have no symptoms, and that signs can take weeks or longer to appear. Itching, odor, a change in discharge and discomfort when urinating are the usual ones. It is curable with treatment from a clinician.

Herpes

Genital herpes can cause painful blisters or sores, but the CDC notes that many people have very mild signs or none, and may not know they have it. Outbreaks can come back. Herpes is not curable, but it is manageable, and clinicians can prescribe medicine that lowers outbreaks and the chance of passing it on.

HPV and cervical changes

Most HPV infections cause no symptoms, and the CDC says most clear on their own. Some types cause genital warts, and some can cause cell changes on the cervix that, over years, may lead to cancer. This is why cervical cancer screening matters. The USPSTF recommends regular screening for women from age 21 to 65, with the method and timing depending on age. HPV is not curable, but its effects are treatable and manageable.

Syphilis

The first sign of syphilis is often a single sore, called a chancre, which is usually painless. It can sit inside the vagina or on the cervix where no one sees it, then heal on its own. A later rash can show up on the palms or soles. Syphilis is curable with treatment from a clinician, and the earlier it is found, the better. In Los Angeles County, the Department of Public Health reports an early syphilis rate of 36 per 100,000 people in 2024.

HIV

Some people have a flu-like illness in the first few weeks after HIV infection. Many do not. After that, HIV can cause no signs for years. HIV is not curable, but the CDC says that with treatment people can live long, healthy lives, and that treatment that keeps the virus undetectable prevents sexual transmission to partners.

Other symptoms worth noting

  • Itching, sores, lumps or bumps on the vulva
  • Pain with sex or with a pelvic exam
  • Lower abdominal or pelvic pain that is new or persistent
  • Sore throat or rectal pain, discharge or bleeding after oral or anal sex

None of these proves anything on its own. Each is a good reason to ask a clinician for a visit and a test.

When to get an STD test for women

Routine screening

The CDC's 2021 guidelines, in line with the USPSTF, recommend:

  • Chlamydia and gonorrhea screening every year for sexually active women under 25.
  • The same yearly screening for older women with risk factors, such as a new partner, more than one partner, or a partner who has an STI.
  • HIV screening at least once for everyone aged 13 to 64 as part of routine care, and more often if there is ongoing chance of exposure. The USPSTF recommends HIV screening for ages 15 to 65.
  • Syphilis, HIV, hepatitis B and chlamydia testing for every pregnancy, with gonorrhea added for those at higher risk.

Your clinician may suggest a different schedule based on your history. Ask them what fits you.

Testing after a possible exposure

A new partner, a condom that broke, a partner who tells you they have an STI, or a partner whose status you do not know are all good reasons to book a visit. You do not need symptoms to ask for a test.

Window periods

A window period is the time between an exposure and the point a test can reliably detect an infection. It differs by infection and by test. For HIV, the CDC says a nucleic acid test can detect infection 10 to 33 days after exposure, an antigen/antibody lab test 18 to 45 days, and a rapid antigen/antibody test from a finger stick 18 to 90 days. Antibody-only tests take longer, 23 to 90 days.

For other infections, ask the clinician how long to wait and whether a repeat test is useful. A test done too early can miss an infection that is still too new to detect, which is why a clinician may suggest testing again later.

What testing involves

For many infections, testing is simple. Chlamydia, gonorrhea and trichomoniasis are often found with a urine sample or a swab, and the CDC says a vaginal swab you collect yourself is accurate for chlamydia and gonorrhea. Syphilis and HIV are usually found with a blood test. A sore may be swabbed for herpes. Throat and rectal swabs are used when sex involved those sites.

You do not have to have a full pelvic exam to be tested for many infections. Tell the clinician what kinds of sex you have had so they can pick the right tests.

Doxy-PEP and who it is for

In 2024, the CDC issued guidance on doxycycline taken after sex to lower the chance of some bacterial STIs. It applies to gay, bisexual and other men who have sex with men and to transgender women who have had a bacterial STI in the past year. The CDC says there is not enough evidence yet to recommend it for cisgender women. If you think it might apply to you, ask a clinician. A clinician decides whether it is right and how to use it.

" + "

Pelvic inflammatory disease and fertility

Pelvic inflammatory disease, or PID, is an infection of the uterus, fallopian tubes or ovaries. The CDC says it is often caused by untreated chlamydia or gonorrhea that has traveled up from the cervix.

PID can cause lower abdominal pain, fever, unusual discharge, pain during sex and bleeding between periods. It can also cause very mild signs or none, so some people do not know they have had it.

The concern is what scarring can do over time. The CDC says PID can lead to long-term pelvic pain, ectopic pregnancy (a pregnancy outside the uterus) and difficulty becoming pregnant. Not everyone who has an untreated infection develops PID, and not everyone who has PID has these effects. But treating the infection early lowers the chance, and this is a main reason clinicians encourage regular screening.

If PID is found, a clinician prescribes treatment. The CDC says prompt treatment helps protect the reproductive organs. If you are worried about fertility, you can ask your clinician about it. Testing is the step that lets treatment happen.

When to see a clinician the same day

Most STI questions can wait for a regular appointment. Some should not. Contact a clinician, urgent care or an emergency department promptly if you have:

  • Severe or sudden lower abdominal or pelvic pain
  • Fever or chills together with pelvic pain, unusual discharge or pain with sex
  • Nausea or vomiting along with pelvic pain
  • Pelvic pain or bleeding while pregnant, or any possible STI symptom during pregnancy
  • Dizziness or fainting with abdominal pain

Emergency care is the right choice for pain that is severe or getting worse fast, because other conditions, including ectopic pregnancy, can look similar.

After a possible HIV exposure

The CDC says post-exposure prophylaxis, or PEP, is HIV medicine started after a possible exposure, and it must begin within 72 hours to work. If this applies to you, contact a clinic, urgent care or emergency department right away. Do not wait for an appointment next week. Los Angeles County's Department of Public Health lists PEP among the services at its sexual health clinics, and its HIV hotline is 800-367-AIDS (2437).

Options for teens and young adults

California law, Family Code section 6926, lets a minor aged 12 or older consent to STI testing and treatment, according to the 2011 bill that amended it. Parents or guardians are not liable for payment for that care. The Department of Public Health's clinics tell patients 12 and older they can be tested and treated without their parents knowing.

Children's Hospital Los Angeles lists an STD service for youth aged 12 to 24 at 3250 Wilshire Blvd., 3rd Floor, Los Angeles, CA 90010, phone 1 (323) 361-7550, Monday through Friday according to the county. Its cost and walk-in policy are not listed there, so check with the hospital.

Free testing at home

The county's Division of HIV and STD Programs offers the I Know program: a free home test for chlamydia and gonorrhea for people with a vagina aged 12 to 44 who live in Los Angeles County. The kit, lab test and return postage are free, and results come online or by phone. The hotline is (800) 758-0880. A home kit is a screening step, so if the result is positive or you have symptoms, a clinician is the next stop.

The California Department of Public Health Office of AIDS has also offered free mailed HIV self-tests through its TakeMeHome program. Its available kits and eligibility may have changed, so check the program's site for current details.

After you test: results, treatment and partners

If a result is positive

A positive result is a medical finding. It says nothing about your character. Bacterial STIs and trichomoniasis are curable with treatment that a clinician prescribes. Herpes, HPV and HIV are not curable, but each is treatable or manageable, and a clinician can explain the options.

Follow the clinician's instructions carefully, and ask when to be re-tested. The CDC recommends re-testing for some infections a few months after treatment.

Telling partners

Partners may need testing and treatment too, even if they feel fine. California law lets clinicians provide expedited partner therapy, where treatment for chlamydia, gonorrhea or other STIs can be given to a partner without an exam, under Health and Safety Code section 120582, as the CDC's California page describes. Ask your clinician whether this applies to you.

Many people find the conversation easier with a plain script: "I tested positive for something and I want you to get tested too." Clinics and the health department can help with notification, often without naming you.

Reporting and privacy

California rules require laboratories to report chlamydia, gonorrhea, syphilis and acute HIV results to the local health department, and require providers to report gonorrhea, syphilis and HIV. Chlamydia has been reportable by laboratories only since October 2019. This reporting is how public health tracks and responds to infections, and it is not a public record of your name. If privacy worries you, ask the clinic how your information is handled.

Pregnancy

California requires everyone giving prenatal care to screen for syphilis. The California Department of Public Health guidance calls for three screens: at the first prenatal visit, in the early third trimester (about 28 weeks) and at delivery. In Los Angeles County, the Department of Public Health reported 102 congenital syphilis cases in 2024. Syphilis in pregnancy is treatable, and early testing protects the baby.

Prevention

The CDC lists several ways to lower the chance of an STI: condoms and dental dams used consistently, regular testing for you and partners, HPV vaccination, hepatitis B vaccination, and PrEP for HIV prevention. Los Angeles County clinics provide PrEP at no patient charge, and the California PrEP Assistance Program helps eligible residents with PrEP costs regardless of immigration status. The county's GetPrEPLA warmline is (213) 351-7699.

Next step

If you have been putting off a test, this is a good week to book it. Pick one option above, call the clinic, and ask what to bring. A test is a routine part of caring for your health.
