Hi There I Am A 30 Year Old Female, I

Hi there I am a 30 year old female, I am pretty healthy, I recently went onto a pescatarian diet, for the past week or so I was experiencing incontinence, a urine sample showed no infection but ++ protein as well as ocassional abdominal cramping. I've noticed my urine is quite cloudy and I have to wait another 8 days for my ultrasound. Should I be concerned? Is this a kidney problem? Thank you!
