Aiyoo, I understand lah betapa confusing ni! A few of my mum friends went through something similar, bleeding during early pregnancy (implantation bleeding) boleh kelirukan orang. Tapi since your test line is still samar and you're experiencing nausea, I think you should cepat go see a doctor or get a blood test (beta hCG) because it's the only way to confirm betul-betul pregnant ke tak, urine tests boleh jadi inconclusive especially if it's very early. Don't wait lah, just go check so you can start your journey properly or settle your mind if it's not. Take care!
