Cure for yeast infection?

Last night I started feeling some discomfort down below. Itchy, sensitive, no doubt the signs of a yeast infection, and I want to get rid of it asap so it doesn't get bad. What is the best, quickest way, to get rid of a yeast infection? I have an otc 7 day cream for it but was wondering if there was anything better. Will even consider an at home remedy if it works better. (side note :today I should have started my period but haven't yet)
