Vaginal itching..

So laat night i took a shower and put on a fresh new underwear and it started like itching down there and it felt like a rash also so i just put a cold babywipe which made it feel waaay better . & this morning babydaddy wanted to have sex and it was type burning me! And it felt itchy inside and i do have white thick discharge but it burns and itches ans it doesnt hurt or burn when i pee tho, and i dont wanna wait till monday to get checked out! Can i use monistat? If so which one ? Or what yall think it might be ?😓😓
