BV vs. yeast infection: how can I tell the difference?
BV usually brings a thin gray/white discharge, a strong fishy odor, and pH > 4.5, often worse after sex or a period, with little itch. Yeast usually brings intense vulvar itch/burn/redness and thick, clumpy (“cottage-cheese”) discharge with normal pH (≤4.5) and little or no odor. Don’t douche. See a clinician for testing if symptoms are new, severe, or keep coming back.
TL;DR
- Odor + thin discharge + higher pH → likely BV.
- Itch + clumpy discharge + normal pH → likely yeast.
- Keep care external-only, fragrance-free, and skip douching. Manage moisture. Red flags or recurrence → clinician.
BV vs Yeast Infection Symptoms (the 10-second snapshot)
BV: thin gray/white discharge, strong fishy/amine odor, pH commonly >4.5, minimal itch; odor often stronger after sex or during/after your period.
Yeast: thick clumpy discharge, intense vulvar itch/burn/redness/swelling, pH typically ≤4.5; odor mild/yeasty or none.
BV vs Yeast: Side-by-Side Comparison
| Symptom/Clue | BV | Yeast |
|---|---|---|
| Discharge | Thin, gray/white, coats vaginal walls | Thick, clumpy “cottage-cheese”; sometimes minimal |
| Odor | Strong fishy/amine; worse after sex/period | Little to none; sometimes faint “yeasty” |
| Itch/Burn | Mild or none | Often intense vulvar itch/burn; redness/swelling common |
| pH | Often > 4.5 | Usually ≤ 4.5 (normal) |
| Common triggers | New/multiple partners, semen (alkaline), menses, douching, smoking, flora shifts | Antibiotics, tight/damp clothing, high-friction days, pregnancy, estrogen shifts |
| After sex | Odor commonly stronger (semen raises pH) | Friction may worsen itch; odor not dominant |
| Prevention focus | Restore/maintain flora balance; skip douching; manage pH-disruptors | Keep area dry/cool; manage friction; plan around antibiotics with clinician |
| See a clinician | Strong odor, new partner, recurrence, pregnancy | Severe itch/swelling/pain, recurrence, pregnancy |
What Raises Your Risk
BV-leaning factors: douching; perfumed products on the vulva; staying in damp fabrics; alkaline semen exposure; new/multiple partners; cycle shifts.
Yeast-leaning factors: antibiotics (flora disruption); tight/occlusive leggings/underwear; heat/sweat; high-friction workouts; pregnancy; estrogen changes; not changing out of swimwear quickly.
pH and Why It Matters
Healthy vaginal pH typically sits around 3.8–4.5, dominated by Lactobacillus. BV tends to push pH above 4.5. Yeast often shows a normal pH. Home pH checks can hint, but diagnosis requires a clinician—especially if symptoms are new, severe, during pregnancy, or recurring.

What Helps (Without Disrupting pH)
Keep routine external-only and fragrance-free. Water is enough most days; if you prefer a cleanser, use a pH-considerate option sparingly and rinse well. Skip douching, powders, and perfumed sprays.
Recurrence and Prevention Basics
If symptoms repeat after sex, after your period, or after antibiotics, get evaluated. For BV-prone patterns, discuss condoms (semen is alkaline) and clinician-guided strategies. For yeast-prone patterns, plan around antibiotics and focus on moisture/friction control. Don’t keep self-treating cycles—get a diagnosis.
When to See a Clinician Now
Strong/foul odor, green/yellow discharge, pelvic or abdominal pain, fever, bleeding not related to your period, symptoms during pregnancy, or symptoms after a new partner. Testing and treatment decisions should come from a qualified clinician.
FAQs
Can BV be itchy?
It can, but BV is more known for odor and thin discharge. Intense itch points more toward yeast.
Can a yeast infection happen without discharge?
Yes. Some people mainly feel itch/burn/redness/swelling with little visible discharge.
Does semen cause BV?
Semen is alkaline and can raise pH, which may aggravate odor in BV-prone people. If you notice a pattern, consider condoms and talk to your clinician.
Does pH tell me for sure whether it’s BV or yeast?
pH is a clue, not a diagnosis. BV often has pH > 4.5; yeast usually has a normal pH. You still need clinical testing.
Can probiotics fix BV or yeast?
Evidence is mixed. Don’t self-treat persistent or severe symptoms; see a clinician for a diagnosis and plan.
How long should I wait before seeing a doctor?
If symptoms are new, severe, recurrent, during pregnancy, or accompanied by fever or pain, book an appointment now.
Conclusion
If you’re wondering how to tell the difference between BV and a yeast infection, look at the pattern: odor + thin discharge + higher pH leans BV; intense itch + clumpy discharge + normal pH leans yeast. Keep care external-only, fragrance-free, and handle moisture fast. If symptoms persist or repeat, see a clinician for testing and a plan that actually works.
