So I know this is really off topic, but I also know many pregnant women get these while pregnant so they might be able to help me. Apparently I have a UTI in addition to the other problems, and I was wondering what they can also cause. I've been cramping and getting back pain where my kidneys are. (They also said I have an upper kidney infection) And the doctor said it can cause vomiting and nausea. Has anyone else ever heard of this? I thought it just caused problems with urination and nothing else. How would it even affect the rest of the body?
