I am currently 18 years old and I have had vaginal discharge since forever, even before I started my period, I know that discharge is normal, I had the normal clear occasional discharge, it then gradually turned into a more white/mucus like discharge, which I have also heard is normal. I dont know if this change has to do with me starting on birth control when I was 15ish or not. After this the discharge became more frequent and uncomfortable, I'd have to go to the washroom every halfhour to 'clean up'. My discharge then turned a light yellow. Now my discharge is a greenish yellow color and looks the same as boogers do. finally I went to a clinic to get it looked at as well as get a pap smear. Everything came back negative! but I know the discharge I am experiancing is not normal, because I've had normal discharge before years ago. I wasn't satified so I went back to the same clinic 2 months later and again all was negative. I went to a dr after starting college and they tested me for gonorrhea, clamidia, trichomoniasis, yeast infection, and two bacterial infections, again all negative. I'ts really stressful and embarassing.. my boyfriend of 3 years is very supportive but It's hard because I am embarassed and dont want to have sex anymore because of this. I finally went to my family doctor and he did some cultures and tests, first they told me it was all negative, but then they called me back and gave me a prescription for a yeast infection, ive been tested for that 3 times and it was negative, but i tried the pills hoping they would work but nothing has changed! also there is a slight smell to the discharge and it gets strong if i dnt change my underwear at least twice a day, or go the the washroom to 'clean up'. I'm past the embarassing stage, and I just want this to go away.. what can I do PLEASE HELP!!!! I cant live with this any longer!!
