Girls, hi everyone, our vulva is itching and burning. And today it's been hurting for two days now since around 10 pm. It's crying and crying even though it already had an accident during the day. Yesterday it went number two twice, the first one very watery, the second one thicker. Has anyone experienced this? What should I do? To the doctor on Wednesday.
