Antibiotics & TTC

I'm increasingly becoming depressed over this situation. I went to see my doctor due to lower abdominal pain and back pain. No other symptoms or indication of problem. Took a urine culture and I'm awaiting results, but until then I'm currently on a antibiotic (Cirpofloxacin, a quinolone antibiotic), which if infection is indicated I will continue to be on for nearly 2 weeks. My fertile week is next week and everything I've read online points to unlikely to ovulate or risk of miscarriage. Another month of disappointment. Can anyone relate or have any similar experiences?
