I Was Treated For UTI, A Week Later Treated For

I was treated for UTI, a week later treated for yeast infection, a week later I had sex and my vagina was red, swollen, and raw after sex. swelling went down after an hour. I returned for a pelvic exam today and was told my results came back negative for yeast infection or BV. Later today I look down there and there is white chunky discharge.
