little help please

So I thought I had a yeast infection but now I'm thinking it's trichomoniasis. I was treating myself like yeast and nothing has changed . I have a white milky discharge, slight itch, frequent urine, and a weird oder (like bad breath). I don't have time to go to doctor between work and getting back into school next month. I have scheduled doc appointments for my birth control and I can't wait for my next date. Can cranberry pills help.? Or maybe monistat?
