I received a call from the dr a few hours ago, saying that I have a uti. they called in a prescription for me. when I picked it up, they didn't tell me anything about it, so I was doing some research on it. the meds that they gave me are nitrofurantoin mono-mcr 100mg. I found online that it's a class B med. a lot of people said it worked for them, and was safe, but others have said it caused a miscarriage. I really dont want to risk the baby. I mean, I am only 5 weeks and 4 days. but I want everything to be healthy! any input would be greatly appreciated!
