Hello, The pain in the vagina is usually due to the sensitivity of the nerves and also of the descent of the presenting part as pregnancy advances leading to pelvic congestion and also radiating pain from the lax pubic joints which occurs as a preparation for delivery. Try taking rest in left lateral position as much as possible and elevate the foot end and also, report the matter to your consultant for further care. If the itching is on the skin, it will get relieved with application of calamine lotion or olive oil and if it is in the vagina, you need to get it examined by your consultant and treated if there is any infection. Wish you safe motherhood.
