Hi! I am 18 and have been dealing with a very sour, like enough to make you gag or cringe, vaginal discharge for about the last two months. It won t go away no matter what I try. Better diet, more water. It just doesn t want to go away. It has never been like this before. It doesn t itch or smell strongly. And it s kind of milky white and sometimes slightly clumpy. I don t know what to do or what it might be.
