My doctor suggested taking cranberry pills daily. I've never had a UTI before this pregnancy. I didn't have any symptoms when I found out I had one. Took antibiotics for a week and it didn't go away. I then had to take another type of antibiotics for a week. To prevent any future problems, I take cranberry pills every day. Also, if you're prone to yeast infections or bacterial infections, my doctor suggested taking probiotics. I take those every day too.
