Severe fungal infection with intense itching during the last month of pregnancy is common and usually treatable safely, but you should avoid self-medicating, especially with oral antifungal tablets. The safest approach is to consult your doctor, who may prescribe pregnancy-safe topical antifungal creams or powders to apply locally, along with advice on keeping the area clean and dry, wearing loose cotton clothing, and avoiding moisture or tight garments. Do not scratch, as this can worsen the infection. Most cases improve well with proper treatment, but it is important to get the right medicine to ensure safety for both you and your baby.
