STD-Yeast Infection? Hi. I was wondering if their was any STDs' that does not have to be associated with or necessarily have symptoms with bumps, rashes, etc around the private area. I'm having a lot of symptoms of STDs' including Trichomonas, Vaginitis, and Pelvic Inflammatory Disease. I've also got a yeast infection right now, and I've had a UTI that keeps coming back. Any ideas? I went to the doctor today, got a papsmear, blood test, and urine test to make sure everything was ok. I'm not sure when I'll get the results back, but I was wondering if someone might could tell me something. 
Some of my symptoms are:

-fever (100-101 degrees F)
-chills
-nausea
-vomiting
-lower-middle back pains (going on 3-4 months now)
-white, cleary, sometimes brown, gooy discharge (before I started the over-the-counter yeast infection treatmeant)
-have noticed a few bumps down there
-itching down there
-burning down there
-rapid pulse (116---UP TO 100 is normal for kids ages 12 to adults)
