Hello, I have had yeast infection before which cleared up by itself. Recently I had taken the emergency I pill after having unprotected sex. My boyfriend had used oil as a lubricant which immediately I started experiencing burning sensation. The burning sensation left but not I have itching and a foul smell from my vagina. The color is also very light slightly yellow discharge which is white also at the same time. I don't understand why it's not cleared off by itself.
