Blood in urine
I just started taking macrobic...and I started my menstrual cycle when I already had it this month. Is something wrong? ## Did you mean Macrobid,the antibiotic containing Nitrofurantoin? Is the blood in your urine or is it menstrual? If you use a form of female contraceptive and take antibiotics, they can affect the efficacy and this may cause breakthrough bleeding. ## My husband's urine has blood in it. What can he use to clear that blood out?
