Do I have a yeast infection?
A vaginal yeast infection is a common overgrowth of Candida — it is not a sexually transmitted infection, and most people get one at some point. Answer a few questions about your symptoms and risk factors to see how concerned to be and what to do next. This is a guide, not a diagnosis.

Many infections are silent. A low result here doesn't rule vaginal yeast infection out. If you've had a new partner or any concern, testing is the only way to be sure.
About vaginal yeast infection
What is vaginal yeast infection?
Itchy, sore, and wondering if it's a yeast infection? You're in very common company — roughly three in four women get at least one in their lifetime, and many get several. It happens when Candida, a fungus that already lives quietly in the body, tips out of balance and overgrows. That overgrowth, not anything you caught, is what brings on the familiar itch and thick white discharge.
Here's the catch worth knowing: yeast gets blamed far more often than it's actually to blame. Studies find fewer than a third of people self-treating for yeast really have it — bacterial vaginosis and trichomoniasis can feel similar but need completely different treatment. So this check helps you read your symptoms, but a quick clinic test is the only way to be certain, especially the first time around.
Screening guidance
Who should get tested for vaginal yeast infection?
Because vaginal yeast infection is often silent, the CDC recommends routine screening for the groups most likely to have it — not just people with symptoms.
-
1
It's your first time with these symptoms
Intense itch plus thick white discharge can also be BV or trich, which look alike but need different medicine — a clinician sorts out which one it is before you treat.
-
2
It keeps coming back
Four or more episodes in a year is worth a proper workup — a culture can pin down the exact species and check for a trigger like uncontrolled blood sugar.
-
3
You have diabetes or a weakened immune system
High blood sugar feeds Candida, and a weakened immune system makes infections more frequent and stubborn — both deserve a clinician's eye.
-
4
Over-the-counter antifungals didn't work
If symptoms don't clear or quickly return, the diagnosis may be off or the yeast may resist the usual treatment — get it checked rather than re-treating blindly.
Timing
When a vaginal yeast infection test is reliable
There's no waiting period here — a yeast infection isn't something you catch on a set date, so there's nothing to count days from. It shows up when the overgrowth starts causing symptoms, often within days of a trigger like antibiotics. The moment to get checked is simply when symptoms appear, especially for a first or recurring episode.
Don't self-treat a first-ever episode, an unclear case, or anything where an STI is possible — a quick pH check and a look under the microscope settle it in minutes.
U.S. data
Vaginal yeast infection in the United States
Vaginal candidiasis is extremely common across all demographics. Approximately 75% of women will have at least one confirmed episode in their lifetime; 40–45% will experience two or more. Approximately 5–8% of reproductive-age women develop recurrent VVC (4+ confirmed episodes per year), a condition that significantly impairs quality of life. VVC rates are highest during pregnancy and in women with uncontrolled diabetes or HIV. Non-albicans Candida species account for a growing proportion of cases, particularly in recurrent and treatment-resistant presentations.

Vaginal yeast infection questions
Common questions about vaginal yeast infection and vaginal yeast infection testing, answered.
Is a yeast infection an STD?
No. Yeast infections aren't sexually transmitted — the fungus is normally present and simply overgrows, often after antibiotics, hormonal changes, or when blood sugar is high. Partners don't usually need treatment.
How do I know it's yeast and not BV?
Yeast typically causes intense itching with a thick, white, odorless 'cottage-cheese' discharge. BV causes a thin, gray discharge with a fishy smell and little itching. Since they're treated differently, it helps to confirm — especially the first time.
What triggers yeast infections?
Common triggers are recent antibiotics, pregnancy or hormonal changes, uncontrolled diabetes, and a weakened immune system. They're not a sign of poor hygiene.
When should I see a clinician instead of using an over-the-counter treatment?
See a clinician for a first-ever episode, if you're pregnant or immunocompromised, if symptoms don't clear with over-the-counter antifungals, or if this keeps happening — because the symptoms can be mistaken for something else.
What does it mean if I keep getting yeast infections?
Four or more in a year is 'recurrent' and worth a clinician's workup — to confirm it's yeast, identify the species, and check for an underlying cause like diabetes. A longer treatment plan usually helps.
Trust & transparency
How this assessment works
-
Grounded in public-health guidance
The questions — and how heavily each answer counts — follow the risk factors and symptoms the CDC and WHO describe for Yeast.
-
A risk guide, not a diagnosis
Your answers produce a risk level — how concerned to be — and flag anything that needs urgent care. Only a lab test can confirm or rule out an infection.

Private by design
It runs in your browser. We never ask for your name, email, or anything that identifies you.
