Dear Doctors, I am a 20 year old female and I am 17 weeks pregnant. I have been having pain on the lower left side of my back. It hurts when I am walking, sleeping on that side, or if I cough. I am worried I might have a kidney infection. My pee has been cloudy, but I have had no pain urinating. I am wondering if that is possible or if something else could be wrong. Thank you so much for your time.
