Yeast Infection During Pregnancy: Symptoms, Causes, and Safe Treatments

Yeast infections are common during pregnancy—especially in the second trimester—when hormonal changes make it easier for yeast to grow in the vaginal area. While these infections don’t usually affect your baby, they can cause discomfort and become harder to treat during pregnancy.

Here’s what you need to know about yeast infections during pregnancy, including symptoms, causes, safe treatment options, and when to call your doctor.

Why Are Yeast Infections Common During Pregnancy?

Pregnancy causes hormonal shifts that change the balance of yeast and bacteria in the vagina. Estrogen levels rise, and vaginal fluids contain more sugar—providing a better environment for yeast to grow.

This imbalance often leads to vaginal candidiasis, commonly known as a yeast infection. Women are more likely to experience this in the second trimester, when hormonal activity is particularly high.

Symptoms of a Yeast Infection While Pregnant

If you have a yeast infection, you may notice:

• Thick, white vaginal discharge (often described as cottage cheese-like)
• Vaginal itching, burning, or soreness
• Redness or swelling of the vulva
• Pain during urination or intercourse
• A mild odor

These symptoms can resemble those of other conditions, like bacterial vaginosis or sexually transmitted infections, which is why proper diagnosis is essential.

Is a Yeast Infection Dangerous During Pregnancy?

Yeast infections are generally not dangerous to your baby, but they can:

• Cause discomfort and irritation
• Lead to oral thrush in newborns if untreated
• Persist longer or return more frequently during pregnancy

To prevent complications or recurrence, it's important to treat infections promptly and safely.

Safe Yeast Infection Treatments During Pregnancy

Not all yeast infection medications are safe during pregnancy. Always consult your doctor before starting any treatment.

Safe Treatment Options:

• Vaginal creams or suppositories with clotrimazole or miconazole (e.g., Monistat)
• Topical antifungal creams like Nystatin
• Prescription vaginal treatments, if over-the-counter options don’t help

Oral medications like Diflucan (fluconazole) are not recommended during pregnancy due to potential risks to the baby.

How Long Does It Take to Clear Up?

Most yeast infections resolve within 10–14 days of starting treatment, but pregnant women may need longer to feel fully symptom-free.

Prevention Tips for Yeast Infections in Pregnancy

To reduce your risk of yeast infections during pregnancy:

• Wear cotton underwear and avoid tight, synthetic fabrics
• Avoid douching and scented soaps or feminine sprays
• Change out of wet swimsuits or gym clothes promptly
• Always wipe front to back after using the restroom
• Avoid hot tubs and overly long baths
• Maintain healthy blood sugar levels (especially if you have gestational diabetes)

When to See a Doctor

Call your doctor if:

• Symptoms don’t improve after three days of treatment
• You’re unsure whether your symptoms are from a yeast infection
• You’ve never had a yeast infection before
• Symptoms return after treatment

Your provider may take a simple vaginal swab to confirm the diagnosis and ensure the right treatment is prescribed.
