I was prescribed Bactrim for a UTI approximately 2 days after I conception. I found out I was pregnant 3-4 weeks later so I’ve only just started taking folic acid supplements now. I’ve read online that Bactrim effects folic acid levels and can lead to Neural Tube Defects. I’m very worried and worried if anyone else has knowledge on Bactrim and taking folic acid supplements late. Thanks in advance.
