Vaginal infections in pregnancy are very common, because hormonal changes can alter the natural vaginal flora. These infections may cause itching, burning, abnormal discharge, foul smell, discomfort during urination or intercourse. As a Gynaecologist with 27+ years of clinical experience, I assure women that most infections are treatable and do not harm the baby if managed early.
This complete 2025 medical guide explains types of vaginal infections, symptoms, causes, risks, safe treatment options, home care measures and when to seek urgent medical attention.
Why Vaginal Infections Are Common in Pregnancy
Pregnancy hormones (estrogen and progesterone) increase natural vaginal moisture and change pH levels, which can increase the growth of certain organisms.
Common Types of Vaginal Infections in Pregnancy
1. Yeast Infection (Candidiasis)
Most common. Caused by overgrowth of the fungus Candida.
- Thick white discharge (curd-like)
- Intense itching
- Burning sensation while urinating
- Redness & swelling
2. Bacterial Vaginosis (BV)
Caused by imbalance of normal bacteria.
- Thin grey/white discharge
- Fishy odour
- Mild itching or burning
3. Trichomoniasis
A sexually transmitted infection (STI).
- Yellow-green discharge
- Foul smell
- Pain during urination
4. Urinary Tract Infection (UTI)
A separate condition but often mistaken for vaginal infection due to similar symptoms.
