I was diagnosed with a UTI last week and have been on Nitro-something since. I take my last pills tomorrow or Wednesday. The doctor said it would affect my tracking, but didn't say how. Does anyone know? Will it cause my ovulation tests to give bad results because it does my urine yellow? Or will it affect when Aunt Flow shows up? Hubby and I are trying to sway for a girl, so I need to cut off around 2-3 days before ovulation actually occurs, but if the test results are being affected, I might need to cut him off completely until after it passes and try again next month.
