Some sexually transmitted infections, including trichomoniasis, can cause changes in vaginal discharge and odor.
Trichomoniasis is a sexually transmitted infection caused by a parasite. Some women experience a strong-smelling discharge that may appear yellowish or greenish, along with itching, irritation, burning during urination, or discomfort during sex. However, some people have few or no symptoms.
Other sexually transmitted infections may also cause vaginal or pelvic symptoms, although odor alone cannot tell you which infection is present.
If you have a new sexual partner, have had unprotected sex, notice unusual discharge, experience pain or burning, or are concerned about exposure to an STI, consider speaking with a healthcare professional about appropriate STI testing.
Getting tested is a normal part of sexual and reproductive health. Many infections can be treated effectively when identified early.
What Is a Normal Vaginal Smell?
A healthy vagina does not have to be completely odorless.
It may have a mild, slightly acidic, musky, or metallic scent depending on the time of the menstrual cycle, physical activity, sexual activity, hormones, and natural vaginal bacteria.
The important thing is a significant change from your normal.
A sudden strong odor that persists, especially when accompanied by unusual discharge, itching, burning, pain, bleeding, or irritation, deserves attention.
What You Should Do If Your Vagina Smells Unusually Bad
Start by avoiding products that can disturb the natural vaginal environment.
Do not douche or wash inside the vagina. Avoid scented sprays, perfumed wipes, fragranced soaps, and deodorizing products designed for the vagina. These products can irritate sensitive tissue and interfere with the natural bacterial balance.
Wash the external vulva gently with warm water. If you use soap, choose a mild, fragrance-free product and keep it on the external area rather than inside the vagina.
Wear breathable underwear and change underwear after heavy sweating or exercise. Avoid remaining in wet swimsuits or damp workout clothes for long periods.
If the odor continues despite these measures, schedule an appointment with a gynecologist or healthcare professional. Depending on your symptoms, they may perform an examination and recommend vaginal testing, STI testing, or other diagnostic tests.
Avoid repeatedly treating yourself based only on symptoms. BV, yeast infections, trichomoniasis, and other conditions can look similar but require different treatments.
When Should You See a Doctor?
You should consider medical evaluation if the odor is strong, persistent, or noticeably different from your usual vaginal scent.
Seek professional care particularly if the odor occurs together with:
- Unusual vaginal discharge
- A fishy or foul-smelling odor
- Severe itching or burning
- Pain during sex
- Burning while urinating
- Pelvic or lower abdominal pain
- Unexplained vaginal bleeding
- Sores, blisters, or significant irritation
- Fever or feeling generally unwell
- Symptoms after possible STI exposure
- Repeated vaginal infections
If you are pregnant and develop a new strong vaginal odor, unusual discharge, bleeding, pelvic pain, fever, or other concerning symptoms, contact your healthcare professional promptly.
Severe pelvic pain, fever, fainting, heavy bleeding, or feeling seriously ill warrants urgent medical attention.
