Vaginal itching problemsss?

im pretty sure i have a yeast infection as i have an itchy vagina and a thick white discharge but i cant get to the doctors for another 2 days and i literally have no money to buy anything from the chemist to ease my itching. the itching is driving me crazzy. what can i do for tonight and tomorrow to ease the itching. any creams or anything i am likely to have at home?
