Scared to do a second course of antibiotics

I have a UTI and was put on an antibiotic but ended up making me sick, I was on it for a week and was told to stop. Well it came back and I'm scared I will have to be put on a second treatment being that I am still in my first trimester. Is there anyway to get rid of it naturally?
