Hello- I have a question regarding an antibiotic I was prescribed when I was 6 weeks pregnant. I had a severe UTI and went to the ER and was given Bactrim. I'm worried about the adverse affects because after reading several articles online, they had all mentioned the drugs risks. I know that the neural tube is supposed to close during the first 4-5 weeks and I'm worried, since Bactrim blocks the absorption of folic acid, that the antibiotic may have interfered with the baby's development. I'm so nervous. Any help would be appreciated!
