How to Decode Your Vaginal Discharge
Vaginal discharge? Find out what normal discharge looks like as well as potential infections and other problems.
Any type of vaginal discharge can seem concerning — but it’s not always a sign of a problem.

“Vaginal discharge can be normal or abnormal,” says Ob/Gyn Oluwatosin Goje, MD. “Not every vaginal discharge means something.”
Understanding what may cause different colors of vaginal discharge can help determine whether it means trouble and how best to treat the problem, if there is one.
Your normal discharge may vary from clear to milky white. But Dr. Goje says a whitish discharge could signal one of two common things:
Vaginal discharge may sometimes change consistency and color during your menstrual cycle. During ovulation, the body can produce a thicker, white, stretchy discharge.
Tip: Keep an eye on your monthly discharge so you know what’s normal for you.
Tip: You can treat it with over-the-counter drugs, such as tioconazole (Monistat®), or with a prescription pill called fluconazole (Diflucan®) or prescription vaginal creams called terazol or clotrimazole. If these don’t work, Dr. Goje says your doctor can test to see whether a fungus other than Candida albicans is present. Vaginal itching could also be caused by an allergic reaction, so let your healthcare provider know if medication does not help your symptoms.
This infection is the most common cause of vaginal discharge. Nearly 30% of women of child-bearing age get it. It often causes an increase in a vaginal discharge that is thin and grayish-white with a foul-smelling, unpleasant fish odor. The discharge and odor are most notable after sex, or you might notice them before and after your period, Dr. Goje says.
Tip: Two vaginal ointments — metronidazole gel and clindamycin cream — can treat the infection. Oral forms of the drugs are also effective. If you have been treated more than three times in a year for BV, consider wearing condoms with sexual intercourse, Dr. Goje says.
This shows up most often in post-menopausal women whose estrogen levels have dropped. The vagina atrophies when the vaginal skin or wall thins out, becoming red and inflamed. A yellow to greenish-yellow discharge appears, and sex is sometimes painful.
Tip: Treatment of DIV can be with clindamycin ointment or steroid ointment in the vagina, but needs a doctor’s prescription. Also, treatment with estrogen cream can relieve itching, burning and pain from vaginal atrophy, Dr. Goje says.
Up to 70% of those with this sexually transmitted infection don’t notice symptoms. But for women who do, an odd-smelling, greenish-yellow discharge that is sometimes frothy is often one of them. Women can also have itching, burning, soreness and redness, along with painful urination.
Tip: As with bacterial vaginosis, a single dose of metronidazole or tinidazole pill by mouth should cure this infection. Some women may need prolonged treatment for five to seven days.
If you notice any of these types of discharge — or any that’s unusual for you — see your doctor or your gynecologist.
Be prepared to discuss the color, consistency and smell of the discharge, as well as any itching and whether it appears related to having sex or your menstrual cycle.
If the first round of treatment doesn’t relieve your symptoms, ask your doctor for more tests.
“There are many tests out there that labs can run to make a diagnosis of an infection,” Dr. Goje says. “I also often recommend that patients keep a diary of their vaginal discharge so they know what’s normal and abnormal for themselves.”
