Aih, memang confusing kan situation macam ni! Based on what you shared, the faint lines and brown bleeding could be a few things, either very early pregnancy, hormonal changes, or maybe implantation bleeding, tapi honestly, since you're getting faint lines on two tests plus the symptoms (demam, tak sedap badan), I think you should pop by your doctor or clinic to do a blood test (beta hCG) to get a clearer answer, sebab urine tests can be tricky at early stages. A few of my mum friends had similar experiences and the blood test really confirmed things properly untuk mereka, jadi much better daripada guessing! Jangan stress sangat first, try to rest and see your doc soon, okay?
