Most vaginal odor has a specific, fixable cause. Use the table below to match your symptom to the most likely explanation.
| Symptom | Most likely cause | See a doctor? |
|---|---|---|
| Fishy, positive test | Bacterial vaginosis (BV) | Yes — antibiotics needed |
| Fishy, negative test | Trich, pH reaction, diet | Request trich + PCR panel |
| Onion/sulphur | Diet, sweat bacteria, TMAU | Only if persistent + new |
| Yeasty/bread-like | Yeast overgrowth (Candida) | OTC first, then doctor |
| Post-sex only | Semen pH reaction or BV flare | If persists beyond 48h |
| After period | Blood pH disruption or BV | If persists beyond 3 days |
| Through pants, not underwear | Fabric/sweat amplification | No, unless other symptoms |
