Hai mama, I understand, super stressful kan when you see a faint line! Samar-samar gitu biasanya sebab hormone masih rendah or masa pengambilan sampel tak optimal. A few of us tried testing lagi after 2-3 hari and dapat clearer result. But honestly, best to see your doctor or do a blood test (HCG) to confirm, that's the most reliable way. Jangan stress dulu, let the professionals check properly ya!
