Vaginal discharge is not a problem to solve — it's a sign your body is working. The vagina is a self-cleaning organ, and discharge is how it removes old cells, maintains moisture, and protects against infection.
Discharge is primarily composed of mucus produced by cervical cells, mixed with vaginal fluid, dead epithelial cells, and bacteria from your vaginal microbiome. What's "normal" varies from person to person.
The Color Guide
Clear
Your vagina is healthy and well-lubricated. Clear discharge increases during ovulation, sexual arousal, exercise, and pregnancy. It may be thin and watery or thick and stretchy.
White or Creamy
Natural lubrication and cleaning process. Common at the beginning and end of your menstrual cycle. Exception: thick, clumpy cottage-cheese texture with itching may indicate a yeast infection.
Light Yellow
Often completely normal — discharge can take on a yellowish tint when exposed to air. If bright or dark yellow with strong odor or irritation, consult a healthcare provider.
Dark Yellow or Yellow-Green
Often a sign of infection — particularly STIs like chlamydia, gonorrhea, or trichomoniasis. May be accompanied by strong odor, pelvic discomfort, or burning during urination.
Green
Almost always a sign of infection. Trichomoniasis is the most common cause, producing frothy, greenish-yellow discharge with a strong odor. Left untreated, these infections can lead to PID.
Gray
The signature of bacterial vaginosis (BV) — the most common vaginal infection in women aged 15–44. Produces thin, grayish-white discharge with a distinctive fishy odor. Requires antibiotic treatment.
Pink
Typically blood-tinged — common at the beginning or end of your period, during ovulation, or after intercourse due to minor cervical irritation. Can also indicate implantation bleeding.
Brown or Dark Red
Old blood. When blood oxidizes it turns brown. Commonly appears at the beginning or end of your period, during implantation, or as breakthrough bleeding on hormonal contraceptives.
When to Seek Care
Gray, green, or bright yellow discharge; a strong or fishy odor; cottage-cheese texture with itching; discharge with pelvic pain, painful sex, or burning urination; and any sudden, significant change from what's normal for you — all warrant a healthcare visit.
Discharge is proof that your vagina is working. Clear, white, and pale yellow are almost always normal. Gray, green, and bright yellow are signals to see a provider. Learn what's normal for your body throughout your cycle, and you'll know exactly when something has changed — and when it's just Tuesday.
