3 days ago I was diagnosed with a UTI. The doctor put me on Macrobid 1 bid for 7days. but when i urinate in the morning, i checked the toilet and see tiny black bugs , shape of apple seed, and it was alive!! i fished it out of toilet, thinking it was blood. what the heck, why am i peeing bugs and how do i get rid of them? will macrobid take care of it or do i need something else?
