BV: When the Party Gets Hijacked
Bacterial vaginosis — or BV — is one of the most common vaginal conditions out there, and also one of the most misunderstood. It’s frustrating, it can be recurrent, and it rarely behaves like a neat, one-and-done infection.
If you’ve ever thought, “I treated this… so why does it feel like it’s back?” — you’re not imagining things. BV isn’t really about catching something. It’s about balance. And balance, especially in a vaginal microbiome, can be surprisingly delicate.
Let’s break it down — clearly, honestly, and without blaming your body.
What Is BV, Really?
BV happens when the vaginal microbiome gets out of balance.
Normally, the vagina is dominated by lactobacillus — helpful bacteria that keep the environment slightly acidic and protective. In BV, those protective bacteria decrease, and other bacteria (often anaerobic ones, like Gardnerella) overgrow.
That shift can lead to:
A strong or fishy odor
Thin gray or white discharge
Vaginal irritation or itching
Or… absolutely no symptoms at all
BV is not caused by being “unclean.”
It’s not a hygiene failure.
It’s a microbiome issue — and microbiomes are sensitive.
Let’s Explain This With a Metaphor
Your vagina is basically hosting a party 24/7.
The good bacteria — the Lactobacilli — are the hosts. They keep things tidy, manage the playlist, and make sure the snacks don’t run out. A few shady characters (aka other bacteria) are always hanging around too, but they’re regulars, and the hosts know how to keep them in check.
When the pH shifts, it’s like someone left the back door unlocked - and the part gets crashed.
The shady ones take their chance. They text all their rowdy friends, who show up uninvited and start taking over. Suddenly, the Lactobacilli are overwhelmed. The aux cord gets snatched. The playlist goes from soft indie to full chaos. The snack table is wrecked. Someone’s yelling. Someone’s crying. Someone’s doing the worm on the kitchen floor.
That’s BV.
It’s not that the invaders are inherently evil — they’re just not supposed to have that much power. And when they multiply too fast, the balance of the party gets thrown off. What was once a chill hang becomes a bacterial rave you did not RSVP to.
So Wait — What Even Is pH?
pH is a measure of how acidic or basic something is.
Soda is very acidic. Bleach is very basic. Those are extremes — but everything, including your vagina, has a pH.
The vaginal pH usually sits between 3.8 and 4.5, which is slightly acidic. That’s the ideal environment for Lactobacilli to thrive. When the pH rises (becomes more alkaline), the party hosts lose control of the guest list.
Your pH is your party’s vibe regulator. Keep it in range, and things stay calm. Let it drift too far, and the vibe gets hijacked.
What Can Shift the pH?
A lot of things. And they’re not always things you’d expect:
- Sex (semen is alkaline, and even saliva can shift your pH)
- New products like washes, wipes, or scented tampons
- Antibiotics that wipe out your good bacteria
- Stress (because of course)
- Hormonal changes
- Menstrual blood
- Tight or sweaty clothes that trap heat and moisture
- Menstrual products left in too long
- Even switching partners — not because anyone’s “dirty,” but because your body might just react differently to theirs
What Are the Signs of BV?
Your body might not throw a full tantrum, but here are the red flags to watch for:
- Gray or off-white discharge
- A strong, fishy odor (especially after sex)
- Itching or irritation
- Just feeling… off down there
How Is BV Diagnosed?
Sometimes, a provider will diagnose BV right in the exam room using classic criteria — things like vaginal pH, discharge appearance, microscopy (looking for “clue cells”), and odor.
But in real life, because of the pace and demands of modern medicine, many clinics rely on a vaginal swab that’s sent to a lab.
That swab doesn’t look for one specific bacteria. Instead, it evaluates the overall bacterial balance:
How much protective lactobacillus is present
How much BV-associated bacteria are present
The ratio between them
That’s why results often come back as:
Highly suggestive of BV
Indeterminate
Unlikely BV
This isn’t vague medicine. BV isn’t a yes-or-no infection — it exists on a spectrum, and these results reflect how far the balance has shifted.
In some clinics, you may also be offered a self-swab instead of a full pelvic exam. This involves inserting a swab into the vagina yourself to collect discharge, which is then analyzed the same way.
If speculums are uncomfortable for you — or you just don’t feel like having a full pelvic exam that day — it’s completely reasonable to ask about this option. Self-swabs can also be helpful when symptoms feel very clear-cut and it’s taking too long to get an appointment. In some cases, clinics can even schedule a quick nursing visit just for a swab.
Bottom line: you have options, and it’s okay to ask about them.
So… Is BV an STD?
Nope. BV isn’t an STI or STD. You don’t “catch” it in the traditional sense - it’s a shift in your own bacterial balance.
But! Certain partners can be more of a trigger than others.
Everyone’s chemistry is different, and your body might react to one partner in a way it doesn’t to another. Things like friction, saliva, semen, or even their personal hygiene habits can make a difference.
If you keep getting BV after sex, it’s okay to talk to your partner about what might help - like washing hands, genitals, or toys before use, or experimenting with different condoms, lubes, or hygiene routines. Sometimes, partner treatment might be necessary (more on this below!)
So How Do You Reset the Balance?
Start with your gyno. BV is incredibly common — and very treatable.
First-line treatment typically involves antibiotics that target the overgrowth of BV-associated bacteria, including:
Metronidazole — taken by mouth or used as a vaginal gel
Clindamycin — usually as a vaginal cream
In certain cases, alternatives like secnidazole or tinidazole
These treatments work well for many people — but not everyone. And needing a different option, a repeat course, or a longer plan does not mean you did anything wrong.
What doesn’t help:
- Douching (don’t do it — seriously)
- Overusing soaps or wipes
- Trying every “feminine wash” on the shelf
- Over-the-counter yeast infection treatments do not treat BV
The best thing you can do in addition to the above treatments is to let your vagina be. She’s got main character energy — she just needs a solid security team.
For some people - especially those dealing with recurrence - treatment may also include maintenance or adjunct strategies alongside antibiotics, which is where things like pH support or boric acid sometimes come in (more on that below).
If symptoms don’t improve, keep coming back, or don’t quite fit the textbook picture, that’s a reason to follow up — not to push through or self-blame.
Recurrence: Let’s Be Honest
BV is notorious for coming back.
Up to half or more of people experience recurrence within a year, even after proper treatment. This doesn’t mean you failed or did something wrong — it means microbiomes are influenced by hormones, sex, stress, antibiotics, and pH shifts.
Recurrent BV often needs:
Repeat or longer treatment
Maintenance strategies (such as weekly metronidazole gel or other over-the-counter products)
And sometimes a conversation about partners
What About Boric Acid?
When BV just won’t leave the group chat — especially if it keeps coming back — some people try boric acid suppositories. These little capsules aren’t antibiotics, but they can help rebalance your vaginal pH and microbiome temporarily - like a hard reset. You’ll insert one vaginally — usually for up to two weeks — but always follow the package directions or check with your provider.
A few notes:
- Boric acid is not for oral use — don’t swallow it
- It’s best as a short-term, not a daily habit
- If BV keeps coming back, talk to a provider to rule out other causes
Playing Defense: Products That Help
If BV keeps showing up uninvited, it’s worth thinking about how to prevent the next takeover.
The best defense is keeping the pH in the normal vaginal range. A pH-balancing gel can help restore a healthier environment after sex, your period, or a particularly sweaty day. It won’t treat an active infection, but it might stop one from forming in the first place. Lactic acid gel is another option to lower the pH back into the normal range. Because it’s an acid, it can cause a mild heat or tingling sensation - so we recommend discussing it with a provider first.
Another strategy is to restore a healthy bacterial balance. We recommend doing this after completing any antibiotics (as they could also kill probiotics) and once the correct pH has been restored. There are plenty of probiotics marketed for vaginal health, but if you want them to work, we recommend placing them directly where they are needed - in the vagina. There are vaginal probiotics suppositories or gels that can help re-introduce lactobacillus into the vagina safely.
Think of both of these as calling in a bouncer before the guests get rowdy.
What About Treating Partners?
This is an area where medicine is still catching up.
Traditionally, partners weren’t treated for BV. But newer research suggests that in cases of recurrent BV with the same partner, treating the partner may help reduce recurrence.
BV-associated bacteria can live on genital skin, and partners may re-introduce the same bacterial pattern after treatment. While partner treatment isn’t routine yet, it’s increasingly viewed as reasonable to discuss — and likely to become more common in the future.
If BV keeps coming back with the same partner, bring this up with your provider. It’s a valid, evolving conversation.
Final Thoughts
BV doesn’t make you dirty. It makes you human.
It’s incredibly common, annoyingly recurrent for some people, and wildly under-talked-about. Everyone’s vaginal microbiome is different — so what throws yours off might not bother someone else.
The goal isn’t perfection.
It’s understanding your triggers, building a toolkit that works for you, and stopping BV before the party gets out of control.
And if it keeps coming back? Don’t give up. Find a provider who’ll take your concerns seriously and work with you to get the vibe right again.
