Microbid symptoms and conditions

YAZ AND UTI'S I have been on Yaz for a few years, and I had been getting bladder infections every time I had sex. My gyn instructed me to take microbid every time before I had sex, and I went to a urologist that said if the microbid was working then we would keep up with that. Recently I made an appointment with a uro/gyn. She instructed me to get an ultrasound on my kidneys because polycystic kidneys run in my family. She also instructed me to take a different birth control pill. Yaz has a diahretic in it and that can cause bladder infections. Since December I have been on a different birth control and have been bladder infection free!
