BV in Pregnancy: Risks, Symptoms, and Safe Treatment Options
Pregnancy is supposed to be a magical time—but for me, it came with more than just morning sickness and weird food cravings. Around my second trimester, I began noticing an unusual odor and discomfort that wasn’t normal. It turned out to be bacterial vaginosis (BV). If you’re pregnant and reading this with similar symptoms, you’re not alone. Understanding BV during pregnancy is critical—not just for your comfort, but also for your baby’s health.
Why BV Matters So Much During Pregnancy
BV is a common vaginal condition caused by an imbalance of bacteria in the vagina. But in pregnancy, this imbalance can have more serious implications. According to NIH, BV is associated with an increased risk of premature birth, low birth weight, and even miscarriage.
The Risk of Preterm Labor
Several studies point out that BV, especially when left untreated, can increase the likelihood of preterm labor. That was something my OB-GYN warned me about after my diagnosis. The bacteria produce harmful byproducts that may trigger uterine contractions early.
Impact on the Placenta
There’s also concern over BV-related inflammation possibly affecting the placenta, reducing nutrient flow to the fetus. That’s why routine prenatal check-ups are essential—and why you shouldn’t dismiss symptoms like odor, discharge, or discomfort as “normal pregnancy things.”

How BV in Pregnancy Feels Different
BV symptoms during pregnancy might present differently than when you’re not expecting. I remember noticing a watery, grayish discharge that didn’t itch or burn—different from yeast infections I’d had in the past.
- Strong, fishy vaginal odor, often more noticeable after intercourse
- Increased vaginal discharge—thin, gray, or white in color
- Occasional pelvic discomfort, especially in later pregnancy stages

What Caught Me Off Guard
I didn’t feel any pain, no burning, no itching. That’s what made it tricky—I almost ignored it. Thankfully, a midwife friend suggested I get it checked. That saved me a lot of stress down the road.

Should You Be Worried About Your Baby?
It’s natural to panic when you hear your baby might be at risk. I sure did. But early detection and treatment go a long way. While the presence of BV doesn’t guarantee complications, it *can* heighten risks if ignored.
Miscarriage Risk and BV
While rare, research from institutions like Mayo Clinic has connected untreated BV with a slightly increased risk of second-trimester miscarriage. It’s not a common outcome, but it’s a valid concern if left unchecked.
Explore the link between BV and miscarriage in more detail in our article BV Miscarriage Risk Facts.
What Helped Me Stay Calm
My care team reassured me that with timely treatment, the prognosis was excellent. I went on metronidazole for a few days, and symptoms subsided quickly. Of course, always consult your OB-GYN before taking any medication.

Treatment Options for BV During Pregnancy
Once I was diagnosed, the first question that popped into my head was, “Is it even safe to treat BV while pregnant?” Thankfully, yes. There are pregnancy-safe antibiotics that your doctor can prescribe to help restore your vaginal flora without putting your baby at risk.
Commonly Prescribed Treatments
Doctors typically recommend one of the following:
- Metronidazole – Often prescribed as an oral tablet or vaginal gel
- Clindamycin – Another safe option, though some women may experience side effects like irritation

How Long Does It Take to Clear Up?
On average, most women experience relief within 7–10 days of starting treatment. In my case, symptoms like odor and discharge disappeared in under a week. That said, it’s crucial to finish the entire course of medication—even if you feel better sooner.

Should Your Partner Be Treated Too?
This was a tricky topic during my OB visit. I asked if my husband needed treatment too. The answer? Usually, no—unless there’s repeated reinfection. But open communication and hygiene can help prevent recurrence.

Natural Remedies: Are They Safe in Pregnancy?
Like many moms-to-be, I was cautious about medications and turned to Google for natural BV remedies. Some options can help—but always consult your provider before trying anything, especially during pregnancy.
Probiotics: A Gentle Support
Adding probiotics to my routine (especially lactobacillus-rich supplements) seemed to support my treatment. They help restore healthy vaginal bacteria and are generally safe when taken orally.
Home Remedies to Be Careful With
I came across suggestions like apple cider vinegar and tea tree oil. While these might work for some outside of pregnancy, I avoided them due to a lack of safety evidence in expecting mothers.

Recurring BV During Pregnancy: What If It Comes Back?
One of my biggest fears was a relapse. BV is notorious for returning—even during pregnancy. And yes, it did return once during my third trimester, which meant another round of antibiotics.
What Causes Recurrence?
There are a few possible triggers:
- Hormonal changes affecting vaginal pH
- Sexual activity without barrier protection
- Inconsistent treatment or not finishing medication
How I Prevented a Second Relapse
After the second flare-up, I became vigilant: breathable underwear, no scented hygiene products, and regular probiotic intake. It helped. I stayed BV-free until delivery.
Explore strategies in Long-Term Solutions for BV and learn about BV Relapse After Antibiotics.
Can Diet Play a Role?
Absolutely. I cut back on sugar and added more fermented foods. Sugar can feed harmful bacteria, tipping the balance in the wrong direction.
Check out what to eat and avoid in our BV Diet Guide:

When to Call Your Doctor Immediately
Even if you’re already being treated for BV, there are signs that shouldn’t be ignored. During my third trimester, I noticed a subtle change in my discharge—slightly greenish, with pelvic cramping. I didn’t wait. I called my OB right away, and it was the right move.
Red Flags to Watch For
- Foul-smelling discharge that changes suddenly
- Pelvic or abdominal pain not related to contractions
- Spotting or bleeding with unusual vaginal symptoms
- Burning during urination combined with discharge
These signs can indicate more than just BV—they might point to infections like UTIs or even preterm labor triggers. For a more accurate diagnosis at home, you can refer to Home Test for BV Accuracy, although nothing replaces a professional assessment.

BV vs Yeast Infection During Pregnancy: Know the Difference
The tricky part? BV and yeast infections are both common during pregnancy—and both can feel similar. I initially assumed I had a yeast infection. It wasn’t until the fishy odor became obvious that I realized something was off.
Quick Symptom Comparison
| Symptom | BV | Yeast Infection |
|---|---|---|
| Discharge Color | Thin, gray/white | Thick, white (cottage cheese) |
| Odor | Fishy, especially after sex | Little to none |
| Itching | Rare | Common and intense |
| Pain or Burning | Mild or absent | Often present |

Helpful Lifestyle Adjustments I Swear By
During the later stages of pregnancy, I adopted small lifestyle tweaks that helped me feel more in control—even with a BV diagnosis. These weren’t just helpful for healing but also boosted my confidence.
My Daily BV-Friendly Routine
- Switched to unscented soap and stopped using feminine sprays
- Wore loose-fitting cotton underwear and avoided synthetic fabrics
- Wiped front to back religiously and stayed hydrated
- Ate plain yogurt or kefir daily for gut and vaginal health
- Used pads instead of tampons when needed (less irritation)
These changes are echoed in our guide on Safe Sex Tips to Avoid BV and BV Prevention Tips.
Can Hormones Alone Trigger BV?
There’s growing evidence that hormonal fluctuations during pregnancy may contribute to BV onset. While the exact mechanism isn’t fully understood, shifting estrogen and pH levels likely play a role.

Wrapping It All Up: You’re Not Alone in This
Dealing with BV during pregnancy isn’t just a medical issue—it’s emotional, confusing, and sometimes scary. I’ve been there, and I hope sharing my story makes you feel less alone. With the right care, BV can be managed effectively without harming your baby or your peace of mind.
Remember, knowledge and proactive care are your best defenses. Always trust your instincts, stay informed, and don’t hesitate to speak up if something doesn’t feel right.
