I complained about itching and creamy off whitish discharge to my nurse few weeks ago, and she tested me for yeast. It came out negative. I also been tested for all STD's twice and they all came out negative. The symptoms went away then a couple days ago the symptoms came back, the white creamy discharge with no odor. It's very uncomfortable. The nurse also said that there might not have been enough yeast for it to be a positive result. What should I do?
