It's one of the most common reasons women see a gynecologist, and one of the least talked about. So let's talk about it.
Many of us grew up with mixed messages about our bodies: that we should smell like flowers down there, that discharge means something is wrong, that a little extra washing can't hurt. None of that is true, and some of it can actually cause the problems we're trying to avoid.
Here's what healthy looks like, the signs worth getting checked, and the habits that help your body take care of itself.
First, what's normal
The vagina cleans itself. It's home to a community of healthy bacteria, mostly Lactobacillus, that keep it slightly acidic and help keep harmful bacteria in check.
- Discharge is normal. Healthy discharge is usually clear to white, and it changes through your cycle: thinner and stretchier around ovulation, thicker at other times.
- A mild scent is normal. A healthy vagina has its own natural scent. It isn't supposed to smell like nothing, or like perfume.
- Changes happen. Your period, sex, pregnancy, birth control, antibiotics and menopause can all shift what's normal for you.
Bacterial vaginosis: common, and more common for us
Bacterial vaginosis, or BV, happens when that healthy balance of bacteria gets thrown off. It's the most common vaginal condition in women of reproductive age, and in a large national study, about half of Black women had it, compared with about 29% of women overall.
Researchers are still working out why. Differences in vaginal bacteria, douching and other habits, stress, and gaps in care likely all play a part. What matters most is that BV is common, it's treatable, and it's nothing to be embarrassed about.
Signs of BV can include:
- Thin, gray or white discharge
- A strong, fishy odor, often stronger after sex
- Sometimes itching or burning, though many women have no symptoms at all
BV isn't considered a sexually transmitted infection, but it's linked to sex, and new partners can make it more likely. Left untreated, it can raise your risk of STIs, including HIV, and of complications during pregnancy. It's treated with prescription antibiotics, as a pill or a gel.
BV comes back for many women within a few months. If that's happening to you, ask your provider about longer treatment plans. A 2025 study also found that treating male partners at the same time cut the chance of BV coming back, so it's worth asking whether that makes sense for you.
BV or a yeast infection?
They're easy to mix up, and treating the wrong one won't help.
- BV: thin, gray or white discharge with a fishy odor. Itching is usually mild or absent.
- Yeast infection: thick, white discharge, often described as looking like cottage cheese, with little or no odor. Itching, burning and redness are common.
Over-the-counter yeast treatments won't treat BV. If it's your first time with these symptoms, if you're not sure which it is, or if treatment hasn't worked, see a provider for a quick test.
Habits that help
- Skip the douche. Douching washes away the good bacteria and is one of the clearest risk factors for BV. Your body doesn't need it.
- Keep it simple. Warm water on the outside (the vulva) is enough. Skip scented washes, sprays, wipes and bath products down there.
- Choose breathable underwear, like cotton, and change out of sweaty workout clothes or wet swimsuits soon.
- Use condoms, which can help lower the risk of BV as well as STIs.
- Be wary of quick fixes. Boric acid, probiotics and home remedies are all over social media. Some may have a place, but talk to your provider before trying them, especially if you're pregnant.
When to get checked
Make an appointment if you notice:
- A change in the color, amount or smell of your discharge
- Itching, burning or irritation that doesn't go away
- Pain during sex or when you pee
- Bleeding between periods or after sex
- Symptoms that keep coming back
If you're pregnant and notice any of these, call your provider promptly.
And if you've been brushed off before, it's okay to say exactly what you need: "This keeps coming back, and I'd like to talk about why and what else we can try."
The through line
Your body knows how to care for itself, and most of the time the best thing you can do is let it. When something feels off, don't wait it out or try to wash it away. Get it checked. It's common, it's treatable, and you deserve answers.
