It is very common to experience vaginal itching during pregnancy due to hormonal changes. If the itching is due to a yeast infection, mild topical antifungal creams like clotrimazole or miconazole are generally safe to use. However, because you also have a genital cyst, it is crucial to consult your OB/GYN or midwife before starting any treatment. They can safely evaluate the cyst and prescribe the exact treatment you need. For immediate comfort, wear loose cotton underwear, apply a cool compress to the area, and avoid scented soaps. Please contact your doctor for a quick, safe evaluation.
