Hi, I am 18 weeks pregnant. last month I was treated for UTI with amoxillin for 5 days, and get culture done after that which showed no growth. But for last a few days, i got UTI again with diarrhea, along with some Ca Oxalate. after urine routine report, my doctor said that there was some growth of bacteria which caused diarrhea as well. i got treated with salines and antibiotics for one day. Now my doctor prescribed me taxim 200mg, celin, Vibact, and econorm for 5 days. How much safe to have antibiotics in pregnancy? How should i prevent this to happen for next time?
