I have been prescribed this for a suspected uti. Test was negative but have had symptoms for a while so the Dr feels its best to treat me in case there is a missed uti, which can be dangerous untreated. Ceflexin seems safe in general, but have also seen a couple of studies were done that indicated birth defect risks with it if taken in early pregnancy. I am 15 weeks so not sure this counts as early pregnancy for a start, and also the studies weren't really too large etc. I am just so worried, but also worried about not treating it im just trying to do whats best. Anyone had it? If you Google any antibiotic or medicine you will always find somewhere that its not safe
