What Causes Vaginal Smell During Pregnancy?

The reasons for vaginal odor vary from case to case. For some, it could be due to lifestyle changes during pregnancy, while for others, it could be a result of infections.

  1. Bacterial vaginosis: It is an infection that could occur in pregnant women. In the early stages of this infection, there is vaginal odor followed by itchiness. If the condition is bothering you a lot, you should see a gynecologist (1).

  1. Abnormal vaginal discharge: Odorless vaginal discharge is usually common during pregnancy. But when you get a strong odor, it could be due to infections that can be treated (3).
  1. Poor hygiene: Wearing tight clothes, using chemical-based products, wipes, sprays, and not bathing for several days could also lead to vaginal odor.
  1. Hormonal changes and diet: Like most other pregnancy changes, the vaginal odor could also be due to the hormonal imbalance during pregnancy. Fluctuation in hormone levels, combined with a change in the dietary patterns during pregnancy, could cause a foul-smelling vagina.
  2. Amniotic fluid leakage: Amniotic fluid is clear, thin, and typically odorless. If you experience amniotic fluid leakage, especially in the last trimester, and notice an unusual or foul smell, it might indicate an infection. A typical amniotic fluid smell may signal a meconium stain or fluid leak during labor. In such cases, seek immediate medical attention (4).

In addition, to the causes mentioned above, a foul vaginal odor could also suggest vaginitis, which is a vaginal infection.

Types of Vaginitis

Vaginitis is a vaginal inflammation that can cause burning sensations, itching, an unpleasant odor, or increased vaginal discharge. Common types of vaginitis include:

  • Yeast Infections: Caused by fungal overgrowth; its symptoms include vaginal burning, irritation, and thick white discharge.
  • Atrophic Vaginitis: A noninfectious condition linked to low estrogen, causing vaginal itching, abnormal discharge, and dryness.
  • Bacterial Vaginosis: A condition resulting from a bacterial overgrowth, leading to vaginal burning, a fishy odor, and discomfort.
  • Trichomoniasis: A sexually-transmitted vaginal infection caused by an organism (parasite). Its symptoms include increased and foul-smelling vaginal discharge (5).
