I am 31 wks pregnant. I have been battling kidney stones for two years prior. I have recently learned that my urinary problems is because of the bug citrobacter korseri- which is latching onto my current kidney stones. I am on my 2nd round of macrobid- now 100mg 2x day for 14 days. I am ordered to do yet another urine analysis and culture in 10 days of start up. I also am restricted as far as fluids- no oj, cran juice. Strictly distiller water. But am taking my prenatal, folic acid, vitamin bcomplex, and acidofulus 3x day. I have been reading alot, and am concerned with taking this medication and also this bacterial infection being spread to my baby boy. And advice? Suggestions? I will b seeing a urologist when the pregnancy is over, until then no one will touch me for the remOval of the stones.
