The other day at my 20wk appt my dr told me that there was protein that showed up in my urine & said it may be a possible urinary tract infection, but I don't think that's the case because whenever I pee it doesn't burn or hurt & I'm not itchy down there or anything, I think I'm starting to leak urine though when my bladder's full (sorry tmi).....so if that's not what it is, what else could it be?
