I had a normal period July 8, yet I got really sick all last week with what I thought might be pregnancy symptoms (breast soreness to an extreme (which I never get monthly), dizziness, nausea, stomach pains, diarrhea, fatigue). I had a urine test done @ clinic July 30 which came back negative - the dr. assured me I wasn't pregnant. I have IBS/reflux and treated myself for that and am feeling better so...maybe it was only that all along. BUT the breast pain is lasting! Does anyone know how soon the urine tests can detect pregnancy? IF you haven't missed a period yet, will the urine test still be definitive? I haven't missed any periods and am due August 8. I would love thoughts - thanks!
