For over two years now, I have been suffering from Chronic Urinary Tract infections. I am being treated for one now, the antibiotics usually seem to clear them up, but they always come back. Recently though, I've been noticing a yellowish discharge, it began this month, about two weeks before my periods due date. It doesn't have an unusual smell, and I'm not itchy down there, but I am alarmed by it and I just want to know what else it could be besides an STD. I went for an exam last Wed, and the Gyno didn't seem to notice the yellow discharge, she just said she noticed a white, milky discharge, but also said it could just be my normal discharge. I did have her check for STD's, and she said if everything turns out negative, then I won't hear from them. Does anyone know what I should do, or any possible reasons why I would be having a yellow discharge? I haven't had unprotected sex in probably over a year.
