I have recurrent vaginal bacterial infections. Often times when I medicate for the infection, I get a yeast infection...back and forth. What can I do to prevent these bacterial infections? I have just one partner (my husband). It seems that when we do have intercourse, I rapidly develop an infection. My symptoms are mild--discomfort in lower left side of pelvis (always the same pin point location), and annoying discharge. I go in for a pap smear when I start to feel fluish--or if I don t know if it s yeast or bacterial. I ve tested positive for both yeast and bacteria at the same time which I found odd. I had endometrial ablation about 7 years ago, so I don t get a period, but periodic spotting. I m 48.
