Group B Strep

I just had my 6 week check up and initial consult two days ago and my Dr left me a message saying everything came back normal except for GBS in my urine culture, meaning I have a UTI caused by GBS right now. I have a lot of drug allergies so there isn't a lot I can take and I'm terrified to take any antibiotics in the first trimester. Of course all I've read are all the risks and scary things and now I'm an emotional and anxiety ridden mess! Any advice? Anyone else been here?
