Hi I've been having thick yellow vaginal discharge for awhile now. Sometimes its darker at other times but still yellow. It sort of just hangs when I urinate. Ive been to the doctor mulitple times and everything has came back normal, including my blood tests. Its not itchy, burning nor does it have an odor. The doctor told me its normal but it doesn't look normal to me especially when the color goes from light to dark at times. Please help
