STD Symptoms in Women: Signs, When to Test and Where in Las Vegas

Many sexually transmitted infections (STIs) cause no symptoms in women. Others cause signs that look a lot like a yeast infection or a urinary tract infection. That is why this guide covers two things: the symptoms of an STD in a female body, and the testing that can find infections when nothing feels different.

It is written for anyone with a vagina, cervix or uterus, whatever their gender or orientation. It also covers what to do next and where to get tested in Las Vegas, including free and low-cost options.

Key takeaways

• Most infections can be present with no symptoms at all. A test is the only way to find out what is going on.
• Symptoms that can point to an STI include unusual discharge, burning when urinating, pelvic pain, pain during sex, bleeding between periods, sores, bumps or a new rash. Other common conditions can cause the same signs, so a clinician needs to sort them out.
• Chlamydia, gonorrhea, syphilis and trichomoniasis are curable with treatment from a clinician. HIV, herpes and HPV are not curable, but they are treatable or manageable.
• Untreated chlamydia and gonorrhea can lead to pelvic inflammatory disease (PID), which can affect fertility. Testing and treatment lower that chance.
• Severe pelvic pain, fever with pelvic pain, or a possible HIV exposure in the last 72 hours are reasons to be seen the same day.
• The Southern Nevada Health District runs a sexual health clinic with sliding-scale fees, and free Express Testing for people without symptoms.

Why most STIs in women are silent

The Centers for Disease Control and Prevention (CDC) says that chlamydia, gonorrhea, trichomoniasis, HPV, herpes and HIV can all be present without causing noticeable symptoms. In women, the infection often sits in the cervix, where nothing can be seen or felt from the outside.

That has two practical effects. First, not having symptoms does not tell you whether an infection is present. Only a test can answer that. Second, an infection can go unnoticed for months while it is still passed to a partner or slowly affects the reproductive organs.

This is not a personal failing. It is how these infections behave. Routine screening exists for exactly this reason.

The local numbers show why screening matters. The Nevada Division of Public and Behavioral Health, Office of State Epidemiology, reported 12,563 chlamydia cases in Clark County in 2023, a rate of 525.2 per 100,000 people. It reported 5,768 gonorrhea cases, a rate of 241.1 per 100,000. Those are only the cases that were tested for, found and reported. They are not a measure of anyone's personal risk.

Symptoms by infection

The table gives a quick overview, based on the CDC's STI Treatment Guidelines (2021) and CDC patient pages. Details for each infection follow it. Remember that a symptom list cannot diagnose anything. A clinician and a lab test can.

Infection	What some women notice	Outlook with care
Chlamydia	Often nothing. Sometimes unusual discharge or burning when urinating.	Curable with treatment from a clinician
Gonorrhea	Often nothing or mild signs: more discharge, burning when urinating, bleeding between periods.	Curable with treatment from a clinician
Trichomoniasis	Often nothing. Sometimes itching, burning, discharge or discomfort when urinating.	Curable with treatment from a clinician
Syphilis	A painless sore in stages, later a rash. Some stages have no signs.	Curable with treatment from a clinician
Genital herpes	Often nothing noticed. Sometimes blisters or sores, itching or pain.	Treatable and manageable, not curable
HPV	Usually nothing. Some types cause genital warts.	Often clears on its own. Related changes are treatable and monitored.
HIV	Some people have flu-like illness weeks after infection. Many have nothing.	Treatable and manageable, not curable

Chlamydia

The CDC says most people with chlamydia have no symptoms. When women do notice something, it may be an unusual vaginal discharge or a burning feeling when urinating. Chlamydia can also infect the throat or rectum, depending on sexual contact, and those infections are often silent too.

Gonorrhea

The CDC notes that gonorrhea symptoms in women are often mild and are easy to mistake for a bladder or vaginal infection. They can include more discharge than usual, burning when urinating and bleeding between periods. Many women have no symptoms.

Trichomoniasis

Trichomoniasis is caused by a parasite. The CDC says most people who have it do not know. Signs, when they appear, can include itching, burning, redness, a change in discharge, or discomfort when urinating. It is curable with treatment from a clinician.

Syphilis

The CDC describes syphilis in stages. The first stage is usually a firm, round, painless sore. In women, that sore can be inside the vagina or on the cervix, where it is easy to miss. The second stage can bring a rash, often on the palms of the hands and soles of the feet, along with fever, swollen glands, tiredness or patchy hair loss. Later stages may have no visible signs at all. Syphilis is curable with treatment from a clinician, and earlier treatment is better.

Genital herpes

Many people with herpes have mild symptoms or none, according to the CDC. When there are symptoms, they can include painful blisters or sores, itching, and burning when urine touches a sore. Outbreaks can come back. Herpes is not curable, but treatment from a clinician can shorten outbreaks and make them less frequent. The CDC does not recommend routine herpes blood testing for people without symptoms. A clinician can talk through whether a test makes sense for you.

HPV

HPV is very common. The CDC says most infections clear on their own, and most people never know they had it. Some types cause genital warts. Other types can cause cell changes on the cervix that, over time, can lead to cervical cancer if they are not found and followed. That is why cervical screening matters, and why it is part of the testing section below.

HIV

The CDC says some people have a flu-like illness, with fever, sore throat, rash, tiredness or swollen glands, within about two to four weeks of HIV infection. Others have no symptoms for years. The only way to know is a test. HIV is not curable, but treatment from a clinician lets people live long, healthy lives and prevents sexual transmission to partners when the virus stays undetectable.

Signs that are worth a test

If something feels different, a test is a reasonable next step. These are signs that clinicians commonly want to look into:

• Vaginal discharge that is new, or has a different color, amount or smell
• Burning or pain when urinating, or needing to urinate more often
• Bleeding between periods or after sex
• Pain during sex
• Pain or pressure in the lower belly or pelvis
• Sores, blisters, bumps or itching on or around the genitals, anus or mouth
• A new rash, especially on the palms or soles
• Swollen glands in the groin, or flu-like illness after a possible exposure
• A partner who tells you they were diagnosed with an STI

None of these signs proves an infection. Yeast infections, bacterial vaginosis, urinary tract infections, skin irritation and hormone changes can all cause similar problems. A clinician can examine you, run the right tests and tell you which it is. Guessing, or treating yourself for the wrong thing, can delay care.

It is also fine to test with no signs at all. In fact, that is when routine screening does the most good.

PID, fertility and pregnancy

Pelvic inflammatory disease

According to the CDC, untreated chlamydia and gonorrhea can spread from the cervix to the uterus, fallopian tubes and ovaries. That is called pelvic inflammatory disease, or PID. Signs can include lower belly pain, fever, pain during sex, unusual discharge and bleeding between periods. Some women have only mild signs, or none.

The CDC says PID can lead to long-term pelvic pain, ectopic pregnancy and difficulty getting pregnant. Scarring in the tubes is the usual reason. Not every untreated infection leads to PID, and not every case of PID affects fertility. But the risk is the reason clinicians encourage testing, and prompt treatment lowers it. PID is treated with antibiotics prescribed by a clinician, and earlier care is better.

If you have lower belly pain, do not wait to see if it passes. See the same-day section below.

Pregnancy

Some infections can affect a pregnancy or a baby. Syphilis is the best-known example, because it can pass to the baby during pregnancy. Nevada law reflects this. Under NRS 442.010, a syphilis test is required at the first prenatal visit and again in the third trimester (weeks 27 to 36). A test at delivery is required for women in certain groups, including those with no prenatal care. If you are pregnant or planning a pregnancy, tell your clinician about any symptoms or exposures, and ask which tests apply to you.

When to test and what a test for women involves

Routine screening

The CDC and the U.S. Preventive Services Task Force (USPSTF) recommend yearly chlamydia and gonorrhea screening for sexually active women under 25. For women 25 and older, they recommend it when there are risk factors, such as a new partner, more than one partner, or a partner who has an STI. The CDC also recommends that everyone aged 13 to 64 be tested for HIV at least once, and more often with ongoing exposure. Syphilis, hepatitis and other tests may be recommended depending on your history, and during pregnancy.

Many people find it easier to book a full panel than to guess which test they need. A clinician can help you choose, and you can say as much or as little about your history as you are comfortable with.

What a test for women involves

A std test for women is usually simple. Depending on the infection and your history, it may include:

• A urine sample or a vaginal swab for chlamydia and gonorrhea. The CDC notes a swab you collect yourself is accepted for these tests.
• A swab of the throat or rectum if those areas were exposed
• A blood draw, or a fingerstick, for HIV and syphilis
• A swab of a sore, if you have one, for herpes
• A vaginal swab for trichomoniasis

A pelvic exam is not always needed. Ask the clinic what to expect when you book.

Window periods

Soon after an exposure, a test may not detect an infection yet. The CDC lists these approximate windows for HIV: a nucleic acid test can detect HIV about 10 to 33 days after exposure, an antigen/antibody lab test on a blood draw about 18 to 45 days, and an antigen/antibody fingerstick test about 18 to 90 days. Antibody tests, including many self-tests, take about 23 to 90 days. If you test inside a window, a clinician may suggest testing again later. For other infections, ask the clinician how soon after an exposure to test.

Cervical screening and HPV

Cervical screening is separate from STI panels, and the two are often confused. The USPSTF recommends cervical cancer screening with a Pap test every three years for ages 21 to 29. For ages 30 to 65, the options are a Pap test every three years, an HPV test every five years, or both together every five years. The CDC recommends HPV vaccination for children at 11 or 12, with catch-up vaccination through age 26. A clinician can discuss vaccination after that age. If you are unsure when you last had a cervical screening, ask when you book.

Doxy-PEP

In 2024, the CDC issued guidance on doxycycline taken after sex to lower the chance of some bacterial STIs. The CDC's recommendation applies to gay and bisexual men and transgender women who had a bacterial STI in the past year. The CDC says there was not enough evidence to recommend it for cisgender women. If this is a question for you, a clinician can talk through the current guidance.

When to see a clinician the same day

Some situations should not wait for the next available appointment. Go to urgent care or an emergency room, or call a clinic and ask to be seen that day, if you have:

• Severe pain in the lower belly or pelvis
• Fever or chills together with pelvic pain, vaginal discharge or pain during sex
• Nausea or vomiting with pelvic pain, or pain on one side with a missed period or a positive pregnancy test
• Any of these symptoms while you are pregnant
• Heavy or unusual vaginal bleeding
• Sores or blisters with fever, or pain so strong it is hard to urinate

Possible HIV exposure is also time-sensitive. The CDC says post-exposure prophylaxis (PEP) works best when it is started as soon as possible, and no later than 72 hours after the exposure. If you may have been exposed in the last three days, call a clinic or go to an emergency department right away. The Southern Nevada Health District lists HIV PEP services and asks people to call (702) 759-1700. Calling early in the day gives you the most options.

If you are not sure whether something counts as urgent, call and describe what you are feeling. Staff can tell you how quickly to be seen.

Where to get tested in Las Vegas

You do not need a big budget to get a std test for women in Las Vegas. Several clinics offer free or sliding-scale testing. Details change, so call or check the clinic's page before you go. For a fuller comparison of options and costs, see our guide to STD testing in Las Vegas, or go straight to the local testing list.

Southern Nevada Health District Sexual Health Clinic

The Southern Nevada Health District (SNHD) runs a Sexual Health Clinic at two Las Vegas locations:

• Main facility: 280 S. Decatur Blvd., Las Vegas, NV 89107
• Fremont Public Health Center: 2830 E. Fremont St., Las Vegas, NV 89104

Both locations use the same phone number, (702) 759-1700. SNHD says walk-ins for STI testing and treatment are available until capacity is reached. At Fremont, it asks people to arrive by 5:30 PM so there is time for processing. Its services include STI and HIV testing, rapid HIV testing and treatment. PrEP and PEP are available by calling (702) 759-1700.

Fees are on a sliding scale. SNHD says charges are based on your income and the number of people in your household, and that you will not be turned away on the day of your visit because you cannot pay. Bring photo ID and proof of income if you can.

SNHD also offers free Express Testing, a walk-in service for people without symptoms. At the Decatur site it runs Monday to Thursday, 7:30 AM to 12 PM and 1 PM to 3:30 PM. At Fremont it runs on Fridays, 7:30 AM to 4 PM. If you have symptoms, SNHD directs you to the regular clinic visit rather than Express Testing. SNHD's own pages list slightly different clinic hours in different places, so confirm hours with the clinic before you go. Its page does not list which tests Express Testing includes, so ask when you call.

More details are on the Southern Nevada Health District sexual health clinic page.

Arlene Cooper Community Health Center at The Center

The LGBTQ Community Center of Southern Nevada runs this health center at 401 S. Maryland Parkway, Las Vegas, NV 89101. It serves people of every gender and orientation. The Center says HIV testing is free and STI screening is low cost, and that certain insurance is billed. Treatment for STIs is provided on site, and PrEP and PEP are listed among its services.

Appointments are highly encouraged, and walk-ins are available for a limited number of patients each day. Call 702-802-5432 for appointments. The health center lists Monday to Friday 8 AM to 6 PM and Saturday 7:30 AM to 4 PM, but the site footer shows different hours, so confirm before you go. See The Center's health center page.

Nevada Health Centers

Nevada Health Centers lists STD testing at two Las Vegas health centers:

• Martin Luther King Family Health Center: 1799 Mount Mariah Dr., Las Vegas, NV 89106. Phone: 702.383.1961 or 800.787.2568
• Nellis Family Medical Center: 691 N. Nellis Blvd., Las Vegas, NV 89110. Phone: 702.563.4662 or 800.787.2568

Nevada Health Centers says it offers a sliding-fee discount program based on family size and income. It also lists assistance with PrEP and PEP. The clinic pages do not say whether walk-ins are accepted, so call to ask about appointments. Learn more on the Nevada Health Centers reproductive health page.

UNLV students

The UNLV Student Health Center, inside the Student Recreation and Wellness Center at 4505 S. Maryland Pkwy., offers testing for sexually transmitted infections, including HIV testing, for students. The phone number is 702-895-3370. Its page does not list prices, so ask when you call. See the UNLV Student Health Center page.

At-home options through the health district

SNHD's Collect2Protect program offers at-home HIV self-test kits and mail-in, self-collect gonorrhea and chlamydia kits to Nevada residents. SNHD said at its 2020 launch that the HIV kits are free, and that the gonorrhea and chlamydia kits carry a fee. The current program page does not list prices, and it says insurance and Medicaid are not accepted. Results can take 7 to 10 business days after the lab receives the specimen. See the Collect2Protect page for current details. A mailed kit does not replace an in-person visit if you have pain, fever or other symptoms.

After the test: treatment, partners and privacy

Treatment

If a test finds a bacterial infection or trichomoniasis, a clinician can prescribe treatment that cures it. For HIV and herpes, treatment from a clinician manages the infection. Follow your clinician's instructions, and ask when to return for follow-up or retesting. The CDC also recommends retesting after treatment for some infections, because reinfection is common.

Partners

Telling a partner can feel hard, but it protects both of you. A clinician or the health department can explain options. Nevada allows expedited partner therapy, in which a clinician may provide treatment for a partner without seeing them first. The CDC lists it as permissible in Nevada as of March 16, 2009. Ask your clinician whether it applies to your situation.

Reporting and privacy

Under Nevada Administrative Code chapter 441A, health care providers must report cases of chlamydia, gonorrhea, syphilis and HIV to the local health authority. This is routine public health practice, and it is how counties track and respond to infections. Ask your clinic how your information will be handled if you have questions.

Age and consent

Nevada Revised Statutes 129.060 states that a minor may give express consent to examination and treatment for any sexually transmitted disease. The statute names no minimum age.

Next steps

If you have been thinking about getting tested, the most useful step is the first one. Pick a clinic from the list above, call, and ask about walk-in hours and costs. Testing is a routine part of health care. It is one of the most effective ways to protect your health and your future options.
