Some vaginal discharge is normal during pregnancy, but a strong or foul smell might be a sign of an infection that needs evaluation.
During pregnancy, it is very common to have some vaginal discharge because of the extra hormones and blood flow. This discharge is usually thin and white, and it might have a slight odor. However, if you notice that the discharge has a strong, unpleasant smell, it could mean that there is an infection, such as bacterial vaginosis or aerobic vaginitis. Research has shown that what is considered pathological vaginal discharge in pregnant women sometimes comes with symptoms like discomfort and may lead to adverse pregnancy outcomes, although not all cases lead to complications. Symptoms to watch for include itching, redness, or irritation along with the odor. Since infections can change the normal balance of bacteria, it is important to consult with a healthcare provider. They can check if an infection is present and offer treatments if needed. Remember, while changes in discharge can be normal during pregnancy, a noticeable foul smell should prompt a professional evaluation to help ensure your well-being and that of your baby.
