Hi i am nearly 12 weeks pregnant and I have a UTI. I have been given antibiotics but have not been so good with taken them. I noticed today that my lower back to one side in incredibly painful. The pain seems to be getting worse as the day is going on. i am taking my antibiotics now but I am worried I have a kidney infection. Does anyone have any experience of this? Do I need more treatment or will the antibiotics for the UTI clear it up even if it has spread to kidneys? thankyou for any advice xxxx
