but just so you can relax for now...some women have that reading because of being around thier period. when we were doing urine samples in school the one girl who was just about to start had that. but with the follow tests that week she was fine.
the teacher explained its very common for women to have that when around thier period.
also you might of just had a mild uti that you didnt notice.
the stress of the fat burning and fasting on your kidneys can make a difference too.
do you get headaches alot?
nausea?
retain water in body when not pms-ing?
